本文实例为大家分享了IOS网络嗅探工具，供大家参考，具体内容如下
一、效果图
二、工程图
三、代码
AppDelegate.h
#import <UIKit/UIKit.h> #import "Reachability.h" @interface AppDelegate : UIResponder <UIApplicationDelegate> { Reachability *reachability; BOOL WarningViaWWAN; } @property (strong, nonatomic) UIWindow *window; - (void)ReachabilitySniff:(Reachability*) curReach; - (void)ReachabilitySniffNotification:(NSNotification* )notification; - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex; @end
AppDelegate.m
#import "AppDelegate.h" #import "RootViewController.h" @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. RootViewController *rootVC=[[RootViewController alloc]init]; UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:rootVC]; self.window.rootViewController=nav; //启动网络嗅探功能 WarningViaWWAN = TRUE; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(ReachabilitySniffNotification:) name:kReachabilityChangedNotification object:nil]; if (!reachability) { reachability = [Reachability reachabilityForInternetConnection]; } [reachability startNotifier]; [self performSelector:@selector(ReachabilitySniff:) withObject:reachability afterDelay:20]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } #pragma mark -网络嗅探 - (void)ReachabilitySniffNotification:(NSNotification* )notification { Reachability* curReach = [notification object]; [self performSelector:@selector(ReachabilitySniff:) withObject:curReach afterDelay:2]; } - (void)ReachabilitySniff:(Reachability*) curReach { NSLog(@"ReachabilitySniffNewWorkStatus"); if (!curReach) { return; } NetworkStatus status = [curReach currentReachabilityStatus]; switch (status) { case ReachableViaWiFi: { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"您正在使用WiFi网络" message:Nil delegate:self cancelButtonTitle:Nil otherButtonTitles:@"本次不再提醒",@"知道了", nil]; [alert show]; break; } case ReachableViaWWAN: { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"您正在使用移动网络，运营商会收取流量费，建议使用WiFi网络" message:Nil delegate:self cancelButtonTitle:Nil otherButtonTitles:@"本次不再提醒",@"知道了", nil]; [alert show]; break; } case NotReachable: { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"没有网络" message:Nil delegate:self cancelButtonTitle:Nil otherButtonTitles:@"本次不再提醒",@"知道了", nil]; [alert show]; break; } } }
