写点常用的宏，有什么需要补充的给我留言哦
- 新加iphoneX的小宏宏
#define iPhoneX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) : NO)
#define iPhoneXR ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) : NO)
#define iPhoneXS_Max ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) : NO)
- 常用的Block解循环。
#ifndef weakify
#if __has_feature(objc_arc)
#define weakify( x ) autoreleasepool{} __weak __typeof__(x) __weak_##x##__ = x;
#else
#define weakify( x ) autoreleasepool{} __block __typeof__(x) __block_##x##__ = x;
#endif
#endif
#ifndef normalize
#if __has_feature(objc_arc)
#define normalize( x ) try{} @finally{} __typeof__(x) x = __weak_##x##__;
#else
#define normalize( x ) try{} @finally{} __typeof__(x) x = __block_##x##__;
#endif
#endif
- 版本号获取
系统版本号
#define SystemVersionNow [[UIDevice currentDevice].systemVersion floatValue]
最少是某个系统版本判断
#define IsAtLeastiOSVersion(X) ([[[UIDevice currentDevice] systemVersion] compare:X options:NSNumericSearch] != NSOrderedAscending)
当前版本号
#define kYYZVersion [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]
小版本号 就是build号
#define kYYZInnerVersion [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]
- 常用设备判断
#define iPhone4 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640,960), [[UIScreen mainScreen] currentMode].size) : NO)
#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640,1136), [[UIScreen mainScreen] currentMode].size) : NO)
#define iPhone6 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? (CGSizeEqualToSize(CGSizeMake(750,1334), [[UIScreen mainScreen] currentMode].size) || CGSizeEqualToSize(CGSizeMake(640,1136), [[UIScreen mainScreen] currentMode].size)) : NO)
#define iPhone6Plus ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? (CGSizeEqualToSize(CGSizeMake(1125,2001), [[UIScreen mainScreen] currentMode].size) || CGSizeEqualToSize(CGSizeMake(1242,2208), [[UIScreen mainScreen] currentMode].size)) : NO)
#define iPhoneX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125,2436), [[UIScreen mainScreen] currentMode].size) : NO)
#define iPhone45Pad (iPhone4||iPhone5||IsiPad)
#define IsiPad ([[UIDevice currentDevice].model rangeOfString:@"iPad"].location != NSNotFound)
#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
- 常用屏幕尺寸获取
#define kScreen ([[UIScreen mainScreen] bounds])
#define kScreenH ([[UIScreen mainScreen]bounds].size.height)
#define kScreenW ([[UIScreen mainScreen]bounds].size.width)
// 状态栏的高度
#define kStatusHeight [[UIApplication sharedApplication] statusBarFrame].size.height
// 导航栏的高度
#define naviHeight 44.0
// 状态栏 + 导航栏 的高度
#define kNavHeight (kStatusHeight + naviHeight)
// tabbar的高度
#define kTarBarHeight YDMainTabbarVC.tabBar.frame.size.height
// 指示器的高度
#define kiPhoneXIndicatorHeight (iPhoneX ? 34.0 : 0)
- 适配比例
#define FONT_RATIO(a) ((((int)ScreenW == 320 || isPad) ? (320.0 / 375) : (((int)ScreenW == 375) ? 1.0 : (414.0 / 375))) * (a))
#define SCREEN_RATIO_CEIL(a) (ceil((((int)ScreenW == 320 || isPad) ? (320.0 / 375) : (((int)ScreenW == 375) ? 1.0 : (414.0 / 375))) * (a) ))//向上取整
#define HEIGHT_RATIO_CEIL(a) (ceil(SCREEN_RATIO_CEIL(a) * ((iPhone4 || isPad || IsiPad) ? (480.0 / 568.0): 1.0)))
- 常用控件获取
// 常规字体大小
#define UIFONTSIZE(font) [UIFont systemFontOfSize:font]
// 创建alloc
#define ALLOC(view) [[view alloc] init]
// NSUserDefaults
#define UserDefaults [NSUserDefaults standardUserDefaults]
// UIApplication
#define UIAPPLICATION [UIApplication sharedApplication]
// window
#define WINDOW [[UIAPPLICATION delegate] window]
- 条件判断
#define EMPTY_STRING(string) \
([string isKindOfClass:[NSNull class]] || \
string == nil || [string isEqualToString:@""])
#define returnCondition(condition) if (condition) {return;}
- 懒加载
#define LazyGetMethod(type, attribute) \
- (type *)attribute \
{ \
if (!_##attribute) { \
_##attribute = [[type alloc] init]; \
} \
return _##attribute; \
}
