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\n",                                           \

[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String],  \

__LINE__, __func__);                                                        \
