iOS之常用宏定义

下面我为大家提供一些常用的宏定义！

 将这些宏定义 加入到.pch使用 再也不用 用一次写一次这么长的程序了

//-------------------获取设备大小-------------------------

//NavBar高度

#define NavigationBar_HEIGHT 44

//获取屏幕 宽度、高度

#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)

#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

 

//-------------------获取设备大小-------------------------

 

 

//-------------------打印日志-------------------------

//DEBUG  模式下打印日志,当前行

#ifdef DEBUG

#   define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);

#else

#   define DLog(...)

#endif

 

 

//重写NSLog,Debug模式下打印日志和当前行数

#if DEBUG

#define NSLog(FORMAT, ...) fprintf(stderr,"\nfunction:%s line:%d content:%s\n", __FUNCTION__, __LINE__, [[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);

#else

#define NSLog(FORMAT, ...) nil

#endif

 

//DEBUG  模式下打印日志,当前行 并弹出一个警告

#ifdef DEBUG

#   define ULog(fmt, ...)  { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"%s\n [Line %d] ", __PRETTY_FUNCTION__, __LINE__] message:[NSString stringWithFormat:fmt, ##__VA_ARGS__]  delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; }
