iOS开发过程中使用一些常用的宏可以提高开发效率，提高代码的重用性；将这些宏放到一个头文件里然后再放到工程中的-Prefix.pch文件中(或者直接放到-Prefix.pch中)直接可以使用,灰常方便。 做了一些分类和注释,可以根据自己习惯再添加或者删除或者修改这些宏进行使用。 #ifndef MacroDefinition_h #define MacroDefinition_h //AppDelegate #define APPDELEGATE [(AppDelegate*)[UIApplication sharedApplication] delegate] //----------------------系统设备相关---------------------------- //获取设备屏幕尺寸 #define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width) #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)//应用尺寸 #define APP_WIDTH [[UIScreen mainScreen]applicationFrame].size.width #define APP_HEIGHT [[UIScreen mainScreen]applicationFrame].size.height //获取系统版本 #define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue] #define CurrentSystemVersion [[UIDevice currentDevice] systemVersion] #define isIOS4 ([[[UIDevice currentDevice] systemVersion] intValue]==4) #define isIOS5 ([[[UIDevice currentDevice] systemVersion] intValue]==5) #define isIOS6 ([[[UIDevice currentDevice] systemVersion] intValue]==6) #define isAfterIOS4 ([[[UIDevice currentDevice] systemVersion] intValue]>4) #define isAfterIOS5 ([[[UIDevice currentDevice] systemVersion] intValue]>5) #define isAfterIOS6 ([[[UIDevice currentDevice] systemVersion] intValue]>6) //获取当前语言 #define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0]) //判断是否 Phone 4/5/6 是否是iPad #define Phone4 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ?
