大家都是知道使用宏不仅方便，而且可以提高开发效率。下面总结了iOS开发过程中的一些常用宏，会持续的往里面添加。
Objective-C
//字符串是否为空 #define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO ) //数组是否为空 #define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0) //字典是否为空 #define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0) //是否是空对象 #define kObjectIsEmpty(_object) (_object == nil || [_object isKindOfClass:[NSNull class]] || ([_object respondsToSelector:@selector(length)] && [(NSData *)_object length] == 0) || ([_object respondsToSelector:@selector(count)] && [(NSArray *)_object count] == 0)) //获取屏幕宽度与高度 #define kScreenWidth ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width) #define kScreenHeight ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.height) #define kScreenSize ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? CGSizeMake([UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale,[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale) : [UIScreen mainScreen].bounds.size) //一些缩写 #define kApplication [UIApplication sharedApplication] #define kKeyWindow [UIApplication sharedApplication].keyWindow #define kAppDelegate [UIApplication sharedApplication].delegate #define kUserDefaults [NSUserDefaults standardUserDefaults] #define kNotificationCenter [NSNotificationCenter defaultCenter] //APP版本号 #define kAppVersion [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"] //系统版本号 #define kSystemVersion [[UIDevice currentDevice] systemVersion] //获取当前语言 #define kCurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0]) //判断是否为iPhone #define kISiPhone (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) //判断是否为iPad #define kISiPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) //获取沙盒Document路径 #define kDocumentPath [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject] //获取沙盒temp路径 #define kTempPath NSTemporaryDirectory() //获取沙盒Cache路径 #define kCachePath [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject] //判断是真机还是模拟器 #if TARGET_OS_IPHONE //真机 #endif #if TARGET_IPHONE_SIMULATOR //模拟器 #endif //开发的时候打印，但是发布的时候不打印的NSLog #ifdef DEBUG #define NSLog(...) NSLog(@"%s 第%d行 n %@nn",__func__,__LINE__,[NSString stringWithFormat:__VA_ARGS__]) #else #define NSLog(...) #endif //颜色 #define kRGBColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0] #define kRGBAColor(r, g, b, a) [UIColor colorWithRed:(r)/255.0 green:(r)/255.0 blue:(r)/255.0 alpha:a] #define kRandomColor KRGBColor(arc4random_uniform(256)/255.0,arc4random_uniform(256)/255.0,arc4random_uniform(256)/255.0) #define kColorWithHex(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16)) / 255.0 green:((float)((rgbValue & 0xFF00) >> 8)) / 255.0 blue:((float)(rgbValue & 0xFF)) / 255.0 alpha:1.0] //弱引用/强引用 #define kWeakSelf(type) __weak typeof(type) weak##type = type; #define kStrongSelf(type) __strong typeof(type) type = weak##type; //由角度转换弧度 #define kDegreesToRadian(x) (M_PI * (x) / 180.0) //由弧度转换角度 #define kRadianToDegrees(radian) (radian * 180.0) / (M_PI) //获取一段时间间隔 #define kStartTime CFAbsoluteTime start = CFAbsoluteTimeGetCurrent(); #define kEndTime NSLog(@"Time: %f", CFAbsoluteTimeGetCurrent() - start)
1.定义尺寸类的宏
DimensMacros.h //状态栏高度 #define STATUS_BAR_HEIGHT 20 //NavBar高度 #define NAVIGATION_BAR_HEIGHT 44 //状态栏 ＋ 导航栏 高度 #define STATUS_AND_NAVIGATION_HEIGHT ((STATUS_BAR_HEIGHT) + (NAVIGATION_BAR_HEIGHT)) //屏幕 rect #define SCREEN_RECT ([UIScreen mainScreen].bounds) #define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width) #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height) #define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATION_BAR_HEIGHT - STATUS_BAR_HEIGHT) //屏幕分辨率 #define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale)) //广告栏高度 #define BANNER_HEIGHT 215 #define STYLEPAGE_HEIGHT 21 #define SMALLTV_HEIGHT 77 #define SMALLTV_WIDTH 110 #define FOLLOW_HEIGHT 220 #define SUBCHANNEL_HEIGHT 62
2.定义沙盒目录文件的宏
PathMacros.h //文件目录 #define kPathTemp NSTemporaryDirectory() #define kPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] #define kPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] #define kPathSearch [kPathDocument stringByAppendingPathComponent:@"Search.plist"] #define kPathMagazine [kPathDocument stringByAppendingPathComponent:@"Magazine"] #define kPathDownloadedMgzs [kPathMagazine stringByAppendingPathComponent:@"DownloadedMgz.plist"] #define kPathDownloadURLs [kPathMagazine stringByAppendingPathComponent:@"DownloadURLs.plist"] #define kPathOperation [kPathMagazine stringByAppendingPathComponent:@"Operation.plist"] #define kPathSplashScreen [kPathCache stringByAppendingPathComponent:@"splashScreen"] #endif
3.工具类的宏

4.通知Notification相关的宏
