    iOS开发经常使用宏定义

    iOS开发中经常须要获取屏幕宽度高度,为view设置颜色,为imgagView设置图片等,我们都可定义一些宏,随时都可拿来使用,方便开发

    <span style="font-size:18px;">#ifndef FingerTips_Macro_Config_h
    #define FingerTips_Macro_Config_h
    
    //获取屏幕 宽度、高度
    #define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
    #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)
    
    //DEBUG  模式下打印日志,当前行
    #ifdef DEBUG
    #define NSLog(format, ...) do {                                                             
    fprintf(stderr, "<%s : %d> %s
    ",                                           
    [[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String],  
    __LINE__, __func__);                                                        
    (NSLog)((format), ##__VA_ARGS__);                                           
    fprintf(stderr, "-------
    ");                                               
    } while (0)
    #else
    #define NSLog(...)
    #endif
    //推断是否 Retina屏、设备是否%fhone 5、是否是iPad
