ios 开发中常用的宏

/** 获得颜色*/
#define kGetColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1]

/** 导航栏默认高度*/
#define NavigationBar_HEIGHT 44

/** 整个屏幕的宽度*/
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)

/** 整个屏幕的宽度*/
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

/** 判断系统版本*/
#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]

/** 判断当前系统版本*/
#define CurrentSystemVersion ([[UIDevice currentDevice] systemVersion])

//判断是否大于 IOS7
#define IS_IOS7 SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")

/** 判断当前系统版本*/
#define CurrentSystemVersion ([[UIDevice currentDevice] systemVersion])


//判断是否是iphone5
#define IS_WIDESCREEN                              ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - (double)568 ) < __DBL_EPSILON__ )

#define IS_IPHONE_5                                ( IS_IPHONE && IS_WIDESCREEN )

//判断字符串是否为空
#define IFISNIL(v)                                 (v = (v != nil) ? v : @"")
//判断NSNumber是否为空
#define IFISNILFORNUMBER(v)                        (v = (v != nil) ? v : [NSNumber numberWithInt:0])
//判断是否是字符串
#define IFISSTR(v)                                 (v = ([v isKindOfClass:[NSString class]]) ? v : [NSString stringWithFormat:@"%@",v])
