判斷真機還是模擬器運行代碼
// 真機
#if TARGET_OS_IPHONE
#endif
// 模擬器
#if TARGET_IPHONE_SIMULATOR
#endif
系統(tǒng)版本
#define IOS8_OR_LATER ([[UIDevice currentDevice].systemVersion doubleValue] >= 8.0)
顏色宏定義
#define RGBCOLOR(r,g,b) [UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:1]
#define RGBACOLOR(r,g,b,a) [UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:(a)]
#define HEXCOLOR(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]
屏幕尺寸
#define SCREEN_HEIGHT [[UIScreen mainScreen] bounds].size.height
#define SCREEN_WIDTH [[UIScreen mainScreen] bounds].size.width
自定義打印
#ifdef DEBUG
#define JSLog(FORMAT, ...) fprintf(stderr,"%s:%d\t%s\n",[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], __LINE__, [[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);
#else
#define JSLog(FORMAT, ...) nil
#endif
本地保存
#define JSDefault [NSUserDefaults standardUserDefaults]
空對象判斷
//是否為空或是[NSNull null]
#define NotNilAndNull(_ref) (((_ref) != nil) && (![(_ref) isEqual:[NSNull null]]))
#define IsNilOrNull(_ref) (((_ref) == nil) || ([(_ref) isEqual:[NSNull null]]))
//字符串是否為空
#define IsStringEmpty(_ref) (((_ref) == nil) || ([(_ref) isEqual:[NSNull null]]) ||([(_ref)isEqualToString:@""]))
//數(shù)組是否為空
#define IsArrayEmpty(_ref) (((_ref) == nil) || ([(_ref) isEqual:[NSNull null]]) ||([(_ref) count] == 0))
線程執(zhí)行方法
#define Foreground_Begin dispatch_async(dispatch_get_main_queue(), ^{
#define Foreground_End });
#define Background_Begin dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{\
@autoreleasepool {
#define Background_End }\
});
宏判斷ARC和非ARC
#if __has_feature(objc_arc)
// ARC
#else
// 非ARC
#endif
角度和弧度轉(zhuǎn)化
#define degreesToRadian(x) (M_PI * (x) / 180.0)
#define radianToDegrees(radian) (radian*180.0)/(M_PI)
用宏創(chuàng)建一個類的單例
#undef AS_SINGLETON
#define AS_SINGLETON( __class ) \
+ (__class *)sharedInstance;
#undef DEF_SINGLETON
#define DEF_SINGLETON( __class ) \
+ (__class *)sharedInstance \
{ \
static dispatch_once_t once; \
static __class * __singleton__; \
dispatch_once( &once, ^{ __singleton__ = [[__class alloc] init]; } ); \
return __singleton__; \
}
防止循環(huán)引用的強弱指針
#define WeakSelf(type) __weak typeof(type) weak##type = type;
#define StrongSelf(type) __strong typeof(type) type = weak##type;
設置UIView圓角
#define ViewBorderRadius(View, Radius, Width, Color)\
\
[View.layer setCornerRadius:(Radius)];\
[View.layer setMasksToBounds:YES];\
[View.layer setBorderWidth:(Width)];\
[View.layer setBorderColor:[Color CGColor]]
角度弧度互轉(zhuǎn)
#define DegreesToRadian(x) (M_PI * (x) / 180.0)
#define RadianToDegrees(radian) (radian*180.0)/(M_PI)
沙盒目錄
//獲取temp#define kPathTemp NSTemporaryDirectory()//獲取沙盒 Document#define kPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]//獲取沙盒 Cache#define kPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]
