iOS 常用宏设置

// 1.日志开关
#ifdef DEBUG
#define CXLog(...) NSLog(__VA_ARGS__)
#else

// 2.判断是否为iOS7
#define iOS7 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)
// 3.获得颜色
#define CXColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1]
// 4.加载JSON对象
#define CXJson(name) [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:[[NSBundle mainBundle] URLForResource:@#name withExtension:nil]] options:NSJSONReadingAllowFragments error:nil]
// 5.全局背景色
#define CXGlobalBg [UIColor colorWithPatternImage:[UIImage imageNamed:@"bg"]]
// 6.判断是否为4inch
#define is4inch ([UIScreen mainScreen].bounds.size.height == 568.0)

1、release时，屏蔽log
#if defined (DEBUG) && DEBUG == 1
#else
#define NSLog(...) {};
#endif
2、在主线程或在后台执行block
#define BACK(block) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), block)
#define MAIN(block) dispatch_async(dispatch_get_main_queue(),block)
3、设备相关
#define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) : NO)
#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)
#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) 

#define CurrentSystemVersion ([[UIDevice currentDevice] systemVersion])
#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])
4、区分模拟器和真机
#if TARGET_OS_IPHONE

//iPhone Device
#endif
#if TARGET_IPHONE_SIMULATOR


//iPhone Simulator
#endif
5、根据是否使用ARC做不同操作
#if __has_feature(objc_arc)
//compiling with ARC
#else
// compiling without ARC
#endif

宏

符合ANSI的预定义宏：

 

__DATE__：表示当前源文件编译时的日期，格式为：月/天/年（Mmm dd yyyy）。

__FILE__：表示当前正在处理的源文件名称。

__LINE__：表示当前正在处理的源文件的行，可以用#line指令修改。

__STDC__：表示是ANSI C标准。只有在编译器选项指定了/Za，并且不是编译C++程序时，被定义为常整数1；否则未定义。

__TIME__：表示当前源文件的最近编译时的时间，格式为：小时/分/秒（hh:mm:ss）。

__TIMESTAMP__：表示当前源文件的最近修改日期和时间，格式为：Ddd Mmm dd hh:mm:ss yyyy，其中Ddd是星期的缩写。
