iOS开发常用的宏定义

#define NavigationBar_HEIGHT  44   //导航栏高度

#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)  //动态获取物理设备的宽度

#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)  //动态获取物理设备的高度

#define SAFE_RELEASE(x) [x release];x=nil  //安全释放

#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]  //获取当前设备系统版本

#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])   //获取当前设备语言

#define COLOR(R, G, B, A)  [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A] //带rgba的颜色值

#define CLEARCOLOR [UIColor clearColor]  //清除背景色

//警告框内容提示

#define degreesToRadian(x) (M_PI * (x) / 180.0)   //角度转弧度
