看到标题你可能会觉得奇怪 推送消息提示框不是系统自己弹出来的吗？ 为什么还要自己自定义呢？
因为项目需求是这样的：最近需要做 远程推送通知 和一个客服系统 包括店铺客服和官方客服两个模块 如果有新的消息推送的时候 如果用户当前不在客服界面的时候 要求无论是在app前台 还是app退到后台 顶部都要弹出系统的那种消息提示框
这样的需求 我们就只能自定义一个在app内 弹出消息提示框
实现步骤如下：
1.我们自定义一个view 为 STPushView 推送消息的提示框view
#import <UIKit/UIKit.h> #import "STPushModel.h" @interface STPushView : UIView /** *推送数据模型 */ @property(nonatomic,strong) STPushModel *model; +(instancetype)shareInstance; + (void)show; + (void)hide; @end
#import "STPushView.h" #import "AppDelegate.h" @interface STPushView() @property (nonatomic, weak) UIImageView *imageV; @property (nonatomic,weak ) UILabel *timLabel; @property (nonatomic,weak ) UILabel *content; @end @implementation STPushView static STPushView *_instance = nil; +(instancetype)shareInstance { static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{ _instance = [[STPushView alloc] init]; }); return _instance; } +(instancetype) allocWithZone:(struct _NSZone *)zone { if (!_instance) { _instance = [super allocWithZone:zone]; } return _instance ; } - (instancetype)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { self.backgroundColor = CUSTOMCOLOR(15, 14, 12); CGFloat margin = 12; UIImageView *imageV = [[UIImageView alloc] init]; imageV.userInteractionEnabled = NO; imageV.image = [UIImage imageNamed:@"logo"]; imageV.layer.cornerRadius = 5; [self addSubview:imageV]; self.imageV = imageV; [imageV mas_makeConstraints:^(MASConstraintMaker *make) { make.left.equalTo(self).offset(margin); make.centerY.equalTo(self.mas_centerY); make.width.mas_equalTo(30); make.height.mas_equalTo(30); }]; UILabel *titleLabel = [[UILabel alloc] init]; titleLabel.textColor = [UIColor whiteColor]; titleLabel.font = [UIFont boldSystemFontOfSize:12]; titleLabel.text = @"121店官方客服"; [self addSubview:titleLabel]; [titleLabel mas_makeConstraints:^(MASConstraintMaker *make) { make.left.equalTo(imageV.mas_right).offset(margin); make.top.equalTo(self.mas_top).offset(margin); make.height.mas_equalTo(16); }]; [titleLabel sizeToFit]; UILabel *timLabel = [[UILabel alloc] init]; timLabel.font = [UIFont systemFontOfSize:12]; timLabel.userInteractionEnabled = NO; timLabel.textColor = [UIColor whiteColor]; timLabel.text = @"刚刚"; timLabel.textColor = [UIColor lightGrayColor]; [self addSubview:timLabel]; self.timLabel = timLabel; [timLabel mas_makeConstraints:^(MASConstraintMaker *make) { make.left.equalTo(titleLabel.mas_right).offset(margin); make.top.equalTo(self.mas_top).offset(margin); make.width.mas_lessThanOrEqualTo(40); make.height.mas_equalTo(16); }]; UILabel *content = [[UILabel alloc] init]; content.numberOfLines = 2; content.font = [UIFont systemFontOfSize:13]; content.textColor = [UIColor whiteColor]; content.userInteractionEnabled = NO; [self addSubview:content]; self.content = content; [content mas_makeConstraints:^(MASConstraintMaker *make) { make.left.equalTo(imageV.mas_right).offset(margin); make.top.equalTo(titleLabel.mas_bottom).offset(-3); make.right.equalTo(self.mas_right).offset(-margin); make.height.mas_equalTo(35); }]; UIView *toolbar = [[UIView alloc] init]; toolbar.backgroundColor = CUSTOMCOLOR(121, 101, 81); toolbar.layer.cornerRadius = 3; [self addSubview:toolbar]; [toolbar mas_makeConstraints:^(MASConstraintMaker *make) { make.width.mas_equalTo(35); make.height.mas_equalTo(6); make.centerX.equalTo(self.mas_centerX); make.bottom.equalTo(self.mas_bottom).offset(-2); }]; } return self; } - (void)setModel:(STPushModel *)model { _model = model; self.timLabel.text = @"刚刚"; self.content.text = model.content; } + (void)show { [UIApplication sharedApplication].statusBarHidden = YES; STPushView *pushView = [STPushView shareInstance]; pushView.hidden = NO; AppDelegate *app = (AppDelegate*)[UIApplication sharedApplication].delegate; [app.window bringSubviewToFront:pushView]; [UIView animateWithDuration:0.25 animations:^{ pushView.frame = CGRectMake(0, 0, SCREEN_WIDTH, pushViewHeight); dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ [UIView animateWithDuration:0.25 animations:^{ pushView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight); } completion:^(BOOL finished) { [UIApplication sharedApplication].statusBarHidden = NO; pushView.hidden = YES; }]; }); }]; } + (void)hide { STPushView *pushView = [STPushView shareInstance]; [UIView animateWithDuration:0.25 animations:^{ pushView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight); } completion:^(BOOL finished) { [UIApplication sharedApplication].statusBarHidden = NO; pushView.hidden = YES; }]; } @end
上面pushView需要一个模型 实现代码如下
// push 推送的model 推送过来的数据如下： /** content = dsfdsnfds; id = 5077; mid = 1270339; title = dsfdsnfds; url = "3"; urlType = 3; **/ #import <Foundation/Foundation.h> @interface STPushModel : STBaseModel<NSCoding> //STBaseModel 是一个继承自NSObject的类 我主要是在这个类中实现了字典转模型的功能 你可以直接修改为NSObject /***id**/ @property (copy,nonatomic) NSString* recordId; /***标题**/ @property (copy, nonatomic) NSString *title; /***url**/ @property (copy, nonatomic) NSString *url; /***url 类型**/ @property (copy, nonatomic) NSString* urlType; /***图标的高度**/ @property (assign,nonatomic) NSString * mid; /***推送内容**/ @property (copy, nonatomic) NSString* content; @end
因为涉及到好几个页面需要使用同样的推送消息数据 进行判断而处理相应的业务 所有我对此模型做了归档处理
#import "STPushModel.h" @implementation STPushModel /** * 保存对象到文件中 * * @param aCoder <#aCoder description#> */ -(void)encodeWithCoder:(NSCoder *)aCoder { [aCoder encodeObject:self.recordId forKey:@"recordId"]; [aCoder encodeObject:self.title forKey:@"title"]; [aCoder encodeObject:self.url forKey:@"url"]; [aCoder encodeObject:self.urlType forKey:@"urlType"]; [aCoder encodeObject:self.mid forKey:@"mid"]; [aCoder encodeObject:self.content forKey:@"content"]; } /** * 从文件中读取对象 * * @param aDecoder <#aDecoder description#> * * @return <#return value description#> */ -(id)initWithCoder:(NSCoder *)aDecoder { //注意：在构造方法中需要先初始化父类的方法 if (self=[super init]) { self.recordId=[aDecoder decodeObjectForKey:@"recordId"]; self.title=[aDecoder decodeObjectForKey:@"title"]; self.url=[aDecoder decodeObjectForKey:@"url"]; self.urlType=[aDecoder decodeObjectForKey:@"urlType"]; self.mid=[aDecoder decodeObjectForKey:@"mid"]; self.content= [aDecoder decodeObjectForKey:@"content"]; } return self; } @end
做好了上面的准备工作之后 接下来我们就需要 APPdelegate里面注册远程推送通知 并且监听推送消息
这里以个推为例子：
第一步在下面的方法中 实现个推的注册方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // 注册个推推送服务 [[GeTuiApilmpl sharedInstance] geTuiRegister]; }
GeTuiApilmpl 是一个单例类 专门用于注册个推的推送方法 实现代码如下：
#import <Foundation/Foundation.h> #import "GeTuiSdk.h" @interface GeTuiApilmpl : NSObject <GeTuiSdkDelegate> + (GeTuiApilmpl *) sharedInstance; - (void) geTuiRegister; @end
#import "GeTuiApilmpl.h" @implementation GeTuiApilmpl + (GeTuiApilmpl *) sharedInstance{ static id instance = nil; static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{ instance = [[self alloc] init]; }); return instance; } - (id)init { self = [super init]; if (self) { NSString *path = [[NSBundle mainBundle] pathForResource:@"libGexin" ofType:@"plist"]; NSDictionary *dic = [NSDictionary dictionaryWithContentsOfFile:path]; [GeTuiSdk startSdkWithAppId:[dic objectForKey:@"GT_APPID"] appKey:[dic objectForKey:@"GT_APPKEY"] appSecret:[dic objectForKey:@"GT_APPSECRET"] delegate:self]; } return self; } #pragma mark - GeTuiSdkDelegate /** SDK启动成功返回cid */ - (void)GeTuiSdkDidRegisterClient:(NSString *)clientId { // [4-EXT-1]: 个推SDK已注册，返回clientId NSLog(@"n>>>[GeTuiSdk RegisterClient]:%@nn", clientId); } /** SDK遇到错误回调 */ - (void)GeTuiSdkDidOccurError:(NSError *)error { // [EXT]:个推错误报告，集成步骤发生的任何错误都在这里通知，如果集成后，无法正常收到消息，查看这里的通知。 NSLog(@"n>>>[GexinSdk error]:%@nn", [error localizedDescription]); } /** SDK收到透传消息回调 */ - (void)GeTuiSdkDidReceivePayload:(NSString *)payloadId andTaskId:(NSString *)taskId andMessageId:(NSString *)aMsgId andOffLine:(BOOL)offLine fromApplication:(NSString *)appId { // [4]: 收到个推消息 NSData *payload = [GeTuiSdk retrivePayloadById:payloadId]; NSString *payloadMsg = nil; if (payload) { payloadMsg = [[NSString alloc] initWithBytes:payload.bytes length:payload.length encoding:NSUTF8StringEncoding]; } NSString *msg = [NSString stringWithFormat:@" payloadId=%@,taskId=%@,messageId:%@,payloadMsg:%@%@", payloadId, taskId, aMsgId, payloadMsg, offLine "<离线消息>" : @""]; NSLog(@"n>>>[GexinSdk ReceivePayload]:%@nn", msg); /** *汇报个推自定义事件 *actionId：用户自定义的actionid，int类型，取值90001-90999。 *taskId：下发任务的任务ID。 *msgId： 下发任务的消息ID。 *返回值：BOOL，YES表示该命令已经提交，NO表示该命令未提交成功。注：该结果不代表服务器收到该条命令 **/ [GeTuiSdk sendFeedbackMessage:90001 taskId:taskId msgId:aMsgId]; } /** SDK收到sendMessage消息回调 */ - (void)GeTuiSdkDidSendMessage:(NSString *)messageId result:(int)result { // [4-EXT]:发送上行消息结果反馈 NSString *msg = [NSString stringWithFormat:@"sendmessage=%@,result=%d", messageId, result]; NSLog(@"n>>>[GexinSdk DidSendMessage]:%@nn", msg); } /** SDK运行状态通知 */ - (void)GeTuiSDkDidNotifySdkState:(SdkStatus)aStatus { // [EXT]:通知SDK运行状态 NSLog(@"n>>>[GexinSdk SdkState]:%unn", aStatus); } /** SDK设置推送模式回调 */ - (void)GeTuiSdkDidSetPushMode:(BOOL)isModeOff error:(NSError *)error { if (error) { NSLog(@"n>>>[GexinSdk SetModeOff Error]:%@nn", [error localizedDescription]); return; } NSLog(@"n>>>[GexinSdk SetModeOff]:%@nn", isModeOff "关闭"); } -(void)geTuiRegister{ }
然后再appDelegate 调用注册远程推送的方法
/** 注册用户通知 */ - (void)registerUserNotification { /* 注册通知(推送) 申请App需要接受来自服务商提供推送消息 */ // 判读系统版本是否是“iOS 8.0”以上 if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 || [UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]) { // 定义用户通知类型(Remote.远程 - Badge.标记 Alert.提示 Sound.声音) UIUserNotificationType types = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound; // 定义用户通知设置 UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; // 注册用户通知 - 根据用户通知设置 [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; [[UIApplication sharedApplication] registerForRemoteNotifications]; } else { // iOS8.0 以前远程推送设置方式 // 定义远程通知类型(Remote.远程 - Badge.标记 Alert.提示 Sound.声音) UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; // 注册远程通知 -根据远程通知类型 [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes]; } }
然后再设置了窗口的跟控制器 之后 调用：addPushView方法 添加 消息提示框STPushView: addPushView实现代码如下
#pragma mark 推送信息展示 //添加推送view - (void)addPushView { STPushView *topView = [STPushView shareInstance]; topView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight); [_window addSubview:topView]; self.topView = topView; topView.hidden = YES; UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hudClick)]; UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(pan:)]; [topView addGestureRecognizer:tap]; [tap requireGestureRecognizerToFail:pan]; topView.gestureRecognizers = @[tap,pan]; } #pragma mark addPushView相关事件 - (void)hudClick { self.topView.userInteractionEnabled = NO; [UIView animateWithDuration:0.25 animations:^{ self.topView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight); }completion:^(BOOL finished) { [UIApplication sharedApplication].statusBarHidden = NO; [self hudClickOperation]; }]; } - (void)hudClickOperation { [self push:nil]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ self.topView.userInteractionEnabled = YES; }); } - (void)pan:(UIPanGestureRecognizer*)pan { CGFloat distance = pushViewHeight-(pushViewHeight-[pan translationInView:self.window].y); if (distance<-20) { [UIView animateWithDuration:0.25 animations:^{ self.topView.frame = CGRectMake(0, -pushViewHeight, SCREEN_WIDTH, pushViewHeight); }completion:^(BOOL finished) { [UIApplication sharedApplication].statusBarHidden = NO; }]; } } //显示pushView - (void)displayPushView { [STPushView show]; }
上面push方法的实现代码如下： 处理逻辑 是根据我自己的项目中需求定的 在这里实现你需要处理的代码
- (void)push:(NSDictionary *)params{ STPushModel *model = [ NSKeyedUnarchiver unarchiveObjectWithFile:KRAPI_PUSH_DATA]; //如果是h5 if ([model.urlType isEqualToString:@"h5"]) { BOOL isStore = [[AnalysisUrl sharedInstance] analysisWebUrl:model.url]; BOOL isGoods = [[AnalysisUrl sharedInstance] analysisGoodsIdWebUrl:model.url]; BOOL isRedBag =[[AnalysisUrl sharedInstance] analyredBagWebUrl:model.url]; BOOL istrace =[[AnalysisUrl sharedInstance] analytraceWebUr:model.url]; BOOL islog =[[AnalysisUrl sharedInstance] analylogWebUrl:model.url]; if (isStore || isGoods) { [[WYPageManager sharedInstance] pushViewControllerWithUrlString:model.url currentUrlString:TRAKER_URL_INDEX]; }else if (isRedBag) { RedBageViewController * regBag =[[RedBageViewController alloc]init]; NSArray *array = [model.url componentsSeparatedByString:@"="]; NSString * string = [array lastObject]; regBag.messageID = string; regBag.redType = @"coupon"; UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController; UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex]; // 跳转到对应的控制器 regBag.hidesBottomBarWhenPushed = YES; [pushClassStance pushViewController:regBag animated:YES]; return; }else if (istrace) { RedBageViewController * regBag =[[RedBageViewController alloc]init]; NSString * string = [StrUtils getIdFromURLString:model.url interceptString:@"/trace/"]; regBag.messageID = string; regBag.redType = @"trace"; UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController; UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex]; // 跳转到对应的控制器 regBag.hidesBottomBarWhenPushed = YES; [pushClassStance pushViewController:regBag animated:YES]; return; }else if (islog) { RedBageViewController * regBag =[[RedBageViewController alloc]init]; NSString * string = [StrUtils getIdFromURLString:model.url interceptString:@"/log/"]; regBag.messageID = string; regBag.redType = @"log"; UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController; UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex]; // 跳转到对应的控制器 regBag.hidesBottomBarWhenPushed = YES; [pushClassStance pushViewController:regBag animated:YES]; return; } else{ if (![model.url isEqualToString:@""]) { UIStoryboard *setStoryboard = [UIStoryboard storyboardWithName:@"UserCenter" bundle:nil]; TotalWebViewController *setVC = [setStoryboard instantiateViewControllerWithIdentifier:@"TotalWebViewController"]; setVC.shopUrl = model.url; setVC.shopTitle = [model.title isEqualToString:@""] " : model.title; UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController; UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex]; setVC.hidesBottomBarWhenPushed = YES; [pushClassStance pushViewController:setVC animated:YES]; } } }else if ([model.urlType isEqualToString:@"native"]){ if ([model.url isEqualToString:@"1"]) { //一元体验购 已经删除 }else if ([model.url isEqualToString:@"2"]){ if (([[STCommonInfo getAuthType] intValue] != 1)) { [self createGroundGlass]; }else{ STProFitViewController *vc = [[STProFitViewController alloc] init]; UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController; UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex]; vc.hidesBottomBarWhenPushed = YES; [pushClassStance pushViewController:vc animated:YES]; } }else if ([model.url isEqualToString:@"3"]){ if (([[STCommonInfo getAuthType] intValue] != 1)) { [self createGroundGlass]; }else{ MessageMainVC *messageVC = [[MessageMainVC alloc] init]; messageVC.hidesBottomBarWhenPushed = YES; UITabBarController *tabVC = (UITabBarController *)self.window.rootViewController; UINavigationController *pushClassStance = (UINavigationController *)tabVC.viewControllers[tabVC.selectedIndex]; [pushClassStance pushViewController:messageVC animated:YES]; } }else if ([model.url hasPrefix:@"http://"]&&([model.url rangeOfString:@"client"].location!=NSNotFound)){ //跳转到客服接 界面 NSString *orgIdString =[[AnalysisUrl sharedInstance] extractOrgId:model.url]; NSString *siteIdString = [[AnalysisUrl sharedInstance] extractOrgIdStoreId:model.url]; [[WYPageManager sharedInstance] pushViewController:@"TLChatViewController" withParam: @{ @"title_nameString":@"官方客服", @"orgIdString":orgIdString, @"siteIdString":siteIdString, @"currentURL":model.url } animated:YES]; } } }
然后再AppDelegate 实现以下方法
/** 自定义：APP被“推送”启动时处理推送消息处理（APP 未启动--》启动）*/- (void)receiveNotificationByLaunchingOptions:(NSDictionary *)launchOptions { if (!launchOptions) return; /* 通过“远程推送”启动APP UIApplicationLaunchOptionsRemoteNotificationKey 远程推送Key */ NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; if (userInfo) { NSLog(@"n>>>[Launching RemoteNotification]:%@", userInfo); } } #pragma mark - 用户通知(推送)回调 _IOS 8.0以上使用 /** 已登记用户通知 */ - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { // 注册远程通知（推送） [application registerForRemoteNotifications]; } #pragma mark - 远程通知(推送)回调 /** 远程通知注册成功委托 */ - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSString *myToken = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]]; myToken = [myToken stringByReplacingOccurrencesOfString:@" " withString:@""]; NSUserDefaults *kr = [NSUserDefaults standardUserDefaults]; [kr setValue:myToken forKey:@"deviceToken"]; [kr synchronize]; [GeTuiSdk registerDeviceToken:myToken]; [[PostDeviceToken sharedInstance] postUpDeviceToken]; NSLog(@"n>>>[DeviceToken Success]:%@nn", myToken); } /** 远程通知注册失败委托 */ - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { [GeTuiSdk registerDeviceToken:@""]; NSLog(@"n>>>[DeviceToken Error]:%@nn", error.description); } #pragma mark - APP运行中接收到通知(推送)处理 /** APP已经接收到“远程”通知(推送) - 透传推送消息 */ - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler { // 处理APN NSLog(@"n>>>[Receive RemoteNotification - Background Fetch]:%@nn", userInfo); completionHandler(UIBackgroundFetchResultNewData); NSString *payLoadString = [[MyPrevent sharedInstance] dictionary:userInfo objectForKey:@"payload"]; [[SpotPunch sharedInstance] spotPunch:@"999.999.1" pointTwo:@"21" info:payLoadString]; // NSUserDefaults *kr = [NSUserDefaults standardUserDefaults]; if (!([[STCommonInfo getAuthType] intValue] != 1)) { NSData *jsonData = [payLoadString dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *jsonDic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil]; STPushModel *model = [STPushModel modelObjectWithDict:jsonDic]; [NSKeyedArchiver archiveRootObject:model toFile:KRAPI_PUSH_DATA]; //如果应用程序在前台 就显示客服提示框 if (application.applicationState == UIApplicationStateActive) { self.topView.model = model; [self displayPushView]; //此方法 的实现 在上一步中 就是展示提示框出来 } } }
然后这些工作做好了之后 就是你需要在个推的后台 配置推送证书 这个配置的步骤 大家可以到个推官网去参考文档 配置
这里我假设 你已经配置到证书了 经过上面的步骤 我们的远程推送通知的方法 基本完成 现在我们运行 测试下 你会发现即使在前台 有新消息推送的时候 顶部也会弹出和系统一样的提示框 点击 跳转到对应的页面的方法逻辑根据你的需要 去做跳转处理
测试效果如下：
用户在后台 收到的消息提示如下：
用户在前台 收到的消息提示如下：
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持查字典教程网。
