iOS常用的宏定义

1.字号

#define kTY_7Font [UIFont systemFontOfSize:7*SCREEN_RATIO]

#define kTY_8Font [UIFont systemFontOfSize:8*SCREEN_RATIO]

#define kTY_9Font [UIFont systemFontOfSize:9*SCREEN_RATIO]

#define kTY_10Font [UIFont systemFontOfSize:10*SCREEN_RATIO]

#define kTY_11Font [UIFont systemFontOfSize:11*SCREEN_RATIO]

#define kTY_12Font [UIFont systemFontOfSize:12*SCREEN_RATIO]

2.系统版本号

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

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

3.打印输出

#ifdef DEBUG

#define NSSLog(FORMAT, ...) fprintf(stderr,"%s:%d\t%s\n",[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], __LINE__, [[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);

#else

#define NSSLog(...)

#endif

4.屏幕的宽高&宽度对比320的比例

//当前设备的屏幕宽度

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

//当前设备的屏幕高度

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

#define SCREEN_RATIO  ([[UIScreen mainScreen] bounds].size.width)/320.0f

5.关于iPhone X的适配的一些宏定义

#define ISiPhoneX \

({BOOL isPhoneX = NO;\

if (@available(iOS11.0, *)) {\

isPhoneX = [[UIApplication sharedApplication] delegate].window.safeAreaInsets.bottom >0.0;\

}\

(isPhoneX);})

//状态栏高度

#define StatusBarHeight (CGFloat)(ISiPhoneX?(44):(20))

// 导航栏高度

#define kNavBarHBelow7  (44)

// 状态栏和导航栏总高度

#define NavBarHAbove7  (ISiPhoneX ? (88):(64))

// TabBar高度

#define TabBar_Height  (ISiPhoneX ? (49+34) :49)

// 顶部安全区域远离高度

#define kTopBarSafeHeight  (CGFloat)(ISiPhoneX?(44):(0))

// 底部安全区域远离高度

#define kBottomSafeHeight  (CGFloat)(ISiPhoneX?(34):(0))

// iPhoneX的状态栏高度差值

#define kTopBarDifHeight    (CGFloat)(ISiPhoneX?(24):(0))

#define STATE_HEIGHT [[UIApplication sharedApplication] statusBarFrame].size.height
