1、长、宽、高
// W H
#define kSCREEN_SIZE [UIScreen mainScreen].bounds.size
#define kSCREEN_WIDTH [UIScreen mainScreen].bounds.size.width
#define kSCREEN_HEIGHT [UIScreen mainScreen].bounds.size.height
#define kSTATUS_H ([[UIApplication sharedApplication] statusBarFrame].size.height>20?44:20) // 适配刘海屏状态栏
#define kTABBAR_H ([[UIApplication sharedApplication] statusBarFrame].size.height>20?83:49) // 适配刘海屏底栏高度
#define kBOTTOM_H ([[UIApplication sharedApplication] statusBarFrame].size.height>20?34:0) // 适配刘海屏底部多出来的高度
2、判断设备、系统版本
//----------------判断当前的iPhone设备/系统版本---------------
// 判断是否为iPhone
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
// 判断是否为iPad
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
// 判断是否为ipod
#define IS_IPOD ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])
//----------------判断系统版本---------------
// 获取系统版本
#define IOS_SYSTEM_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]
// 判断 iOS 8 或更高的系统版本
#define IOS_VERSION_8_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0)? (YES):(NO))
// 判断 iOS 10 或更高的系统版本
#define IOS_VERSION_10_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue] >=10.0)? (YES):(NO))
//----------------判断机型 根据尺寸---------------
// 判断是否为 iPhone 4/4S - 3.5 inch
#define iPhone4_4S [[UIScreen mainScreen] bounds].size.width == 320.0f && [[UIScreen mainScreen] bounds].size.height == 480.0f
// 判断是否为 iPhone 5/5SE - 4.0 inch
#define iPhone5_5SE [[UIScreen mainScreen] bounds].size.width == 320.0f && [[UIScreen mainScreen] bounds].size.height == 568.0f
// 判断是否为iPhone 6/6S/7/8 - 4.7 inch
#define iPhone6_6S [[UIScreen mainScreen] bounds].size.width == 375.0f && [[UIScreen mainScreen] bounds].size.height == 667.0f
// 判断是否为iPhone 6Plus/6SPlus/7P/8P - 5.5 inch
#define iPhone6Plus_8Plus [[UIScreen mainScreen] bounds].size.width == 414.0f && [[UIScreen mainScreen] bounds].size.height == 736.0f
// 判断是否为iPhoneX - 5.8 inch
#define iPhoneX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) : NO)
// 判断是否为iPhoneXS - 5.8 inch
#define iPhoneXS ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) : NO)
// 判断是否为iPhoneXR - 6.1 inch
#define iPhoneXR ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) : NO)
// 判断是否为iPhoneXS MAX - 6.5 inch
#define iPhoneXSMax ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) : NO)
// 主要是用于区分是否是 刘海屏
#define LiuHaiPhone \
({BOOL isLiuHaiPhone = NO;\
if (@available(iOS 11.0, *)) {\
isLiuHaiPhone = [[UIApplication sharedApplication] delegate].window.safeAreaInsets.bottom > 0.0;\
}\
(isLiuHaiPhone);})
3、dispatch_main_async_safe
#ifndef dispatch_main_async_safe
#define dispatch_main_async_safe(block)\
if (strcmp(dispatch_queue_get_label(DISPATCH_CURRENT_QUEUE_LABEL), dispatch_queue_get_label(dispatch_get_main_queue())) == 0) {\
block();\
} else {\
dispatch_async(dispatch_get_main_queue(), block);\
}
#endif
How to use?
dispatch_main_async_safe(^{
// UI in Main Thread
});

4、WeakSelf、StrongSelf
#define WeakSelf(type) __weak typeof(type) weak##type = type;
#define StrongSelf(type) __strong typeof(type) type = weak##type;
__weak __typeof(self)weakSelf = self;
AFNetworkReachabilityStatusBlock callback = ^(AFNetworkReachabilityStatus status) {
__strong __typeof(weakSelf)strongSelf = weakSelf;
strongSelf.networkReachabilityStatus = status;
if (strongSelf.networkReachabilityStatusBlock) {
strongSelf.networkReachabilityStatusBlock(status);
}
};
// 使用一：
WeakSelf(self);
[btn mas_makeConstraints:^(MASConstraintMaker *make) {
StrongSelf(self);
make.left.equalTo(self.view);
}];
// 使用二：
WeakSelf(self);
[btn mas_updateConstraints:^(MASConstraintMaker *make) {
make.right.equalTo(weakself.view);
}];
5、View 圆角、边框
#define LXViewBorderRadius(View, Radius, Width, UIColor)\
\
[View.layer setCornerRadius:(Radius)];\
[View.layer setMasksToBounds:YES];\
[View.layer setBorderWidth:(Width)];\
[View.layer setBorderColor:[Color CGColor]]
6、获取沙盒路径
//--------------沙盒目录文件路径---------------
// 获取沙盒主目录路径
#define LXSBPath_Home = NSHomeDirectory();
//获取沙盒 Document
#define LXSBPath_Document [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]
//获取沙盒 Library
#define LXSBPath_Library [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) lastObject];
//获取沙盒 Cache
#define LXSBPath_Cache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]
//获取temp
#define LXSBPath_Temp NSTemporaryDirectory()
7、随机数
//--------------生成随机数---------------
#define LXRandNum(i) arc4random()%i // [0,i) 范围内随机数
#define LXRandNum_FromTo(i,j) (i + (arc4random() % (j – i + 1)))
8、颜色设置相关
//---------------Colour-------------------
// 设置随机颜色
#define LXRandomColor [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]
// 设置RGB颜色/设置RGBA颜色
#define LXRGBAColor(r, g, b, a) [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:a]
#define LXRGBColor(r, g, b) LXRGBAColor(r,g,b,1.0f)
// 十六进制数值 eg:@"#3499DB"
#define LXCOLOR_WITH_HEX [UIColor colorFromHexString: hexValue]
#define LXCOLOR_WITH_HEX_1(hexValue) [UIColor colorWithRed:((float)((hexValue & 0xFF0000) >> 16)) / 255.0 green:((float)((hexValue & 0xFF00) >> 8)) / 255.0 blue:((float)(hexValue & 0xFF)) / 255.0 alpha:1.0f]
9、NSLog
//-------------- NSLog在release下不输出 ---------------
#ifndef __OPTIMIZE__
#define NSLog(...) NSLog(__VA_ARGS__)
#else
# define NSLog(...) {}
#endif
