iOS 常用的宏定义

屏幕尺寸

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

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

手机型号

 #define kISiPhone (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

 #define kScreenMaxLength (MAX(kScreenWidth, kScreenHeight))

 #define kScreenMinLength (MIN(kScreenWidth, kScreenHeight))

#define kISiPhone5 (kISiPhone && kScreenMaxLength == 568.0)

#define kISiPhone6 (kISiPhone && kScreenMaxLength == 667.0) #define kISiPhone6P (kISiPhone && kScreenMaxLength == 736.0) #define kISiPhoneX (kISiPhone && kScreenMaxLength == 812.0) #define kISiPhoneXr (kISiPhone && kScreenMaxLength == 896.0) #define kISiPhoneXX (kISiPhone && kScreenMaxLength > 811.0) #define IOS8 ([[[UIDevice currentDevice] systemVersion] doubleValue] >= 8.0)


系统版本
#define IOS810 ([[[UIDevice currentDevice] systemVersion] doubleValue] >= 10.0)

适配尺寸

//6为标准适配的,如果需要其他标准可以修改
#define kScale_W(w) ((kScreenWidth)/375) * (w)
#define kScale_H(h) (kScreenHeight/667) * (h) //状态栏高度 #define kStatusBarHeight [[UIApplication sharedApplication] statusBarFrame].size.height //状态栏高度 #define StatusBarHeight (kISiPhoneX?44:20) //标签栏高度 #define kTabBarHeight (StatusBarHeight > 20 ? 83 : 49) //导航栏高度 #define kNavBarHeight (StatusBarHeight + 44) //安全区高度 #define kSafeAreaBottom (kISiPhoneX ? 34 : 0)

字体大小

#define kBoldFont(x) [UIFont boldSystemFontOfSize:x]

#define kFont(x) [UIFont systemFontOfSize:x]

颜色设置

//RGB格式
#define kRGB(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]
//RGBA格式 #define kRGBA(r, g, b, a) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a] //随机颜色 #define kRandomColor [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]
