iOS常用宏定义汇总

第一次准备写点东西，整理了一下项目中常用到的宏定义。

1.获取屏幕宽度与高度

#define SLScreenHeight [UIScreen mainScreen].bounds.size.width

#define SLScreenWidth [UIScreen mainScreen].bounds.size.height

2.根据rgb获得颜色

#define SLColor(r,g,b) [UIColor colorWithRed:(r) / 255.0 green:(g) / 255.0 blue:(b) / 255.0 alpha:1.0]

#define SLColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

3.版本判断

#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]

3.字号设置

#define SLFont(F) [UIFont systemFontOfSize:(F)]

4.由角度转换弧度 由弧度转换角度

#define SLDegreesToRadian(x)  (M_PI * (x) /180.0)

#define SLRadianToDegrees(radian)  (radian*180.0)/(M_PI)

5.获取当前语言

#define SLCurrentLanguage ([[NSLocale preferredLanguages]objectAtIndex:0])

6.沙盒目录文件

//获取temp

#define SLPathTemp NSTemporaryDirectory()

//获取沙盒 Document

#define SLPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]

//获取沙盒 Cache

#define SLPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]

7.判断字符串是否为空

#define SLStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length]< 1 ? YES : NO )

8.判断数组是否为空

#define SLArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0)

9.判断字典是否为空

#define SLDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0)

10.常用缩写

#define SLApplication  [UIApplication sharedApplication]

#define SLkKeyWindow  [UIApplication sharedApplication].keyWindow

#define SLAppDelegate  [UIApplication sharedApplication].delegate

#define SLUserDefaults  [NSUserDefaults standardUserDefaults]

#define SLNotificationCenter [NSNotificationCenter defaultCenter]

11.APP版本号

#define SLAppVersion [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]

12.获取当前语言

#define SLCurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])

13.判断是否为iPhone

#define SLISiPhone (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

14.判断是否为iPad

#define SLISiPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

15.随机生成颜色

#define SLRandomColor  [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]
