iOS开发常用宏定义

 

//获取屏幕 宽度、高度
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

// 根据版本号导入文件
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif

　　

/**
 *  版本号
 *
 *  @param  CFBundleShortVersionString
 *
 *  @return kVersion
 */
#define kVersion [NSString stringWithFormat:@"%@",[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"]]

　

/**
 *  iPhone or iPad
 */
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_PAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

　　

#define IPHONE4S ((SCREEN.height == 480.0f)?YES:NO)
#define IPHONE5 ((SCREEN.height == 568.0f)?YES:NO)
#define IPHONE6 ((SCREEN.height == 667.0f)?YES:NO)
#define IPHONE6P ((SCREEN.height == 736.0f)?YES:NO)

// 操作系统宏
#define IOS10_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0)
#define IOS9_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 9.0)
#define IOS8_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
#define IOS7_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)

// 线程开启宏
#define dispatch_main_async_withsafe(block)
if ([NSThread isMainThread]) {
block();
} else {
dispatch_async(dispatch_get_main_queue(), block);
}

#define dispatch_global_async_withsafe(block)
if ([NSThread isMainThread]) {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),block);
} else {
block();
}

单粒模式宏定义

#pragma mark - 实例定义
#define SingletenInterface 
+ (instancetype)sharedInstance;


#pragma mark - 定义单例代码块
#define SingletenImpl 
static id _instace; 

+ (id)allocWithZone:(struct _NSZone *)zone 
{ 
    static dispatch_once_t onceToken; 
    dispatch_once(&onceToken, ^{ 
        _instace = [super allocWithZone:zone]; 
    }); 
    return _instace; 
} 

- (id)copyWithZone:(NSZone *)zone 
{ 
    return _instace; 
} 

+ (instancetype)sharedInstance 
{ 
    static dispatch_once_t onceToken; 
    dispatch_once(&onceToken, ^{ 
        _instace = [[self alloc] init]; 
    }); 
    return _instace; 
} 

 宏中使用##,传入参数作为shared方法名称:

//
//  Singleten.h
//  可变参数测试

#endif /* Singleten_h */

定义开发模式和发布模式条件宏

#ifdef DEBUG
#define CCDebugLog(fmt,...) 
if ([[NSThread currentThread] isMainThread]) {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSString *newFrt = [@"[文件名:%s]
 [函数名:%s]
 [行号:%d]
" stringByAppendingString:fmt ];
NSString *logContent = [NSString stringWithFormat:newFrt,__FILE__, __FUNCTION__, __LINE__,##__VA_ARGS__];
logContent = [NSString stringWithFormat:@"%@%@%@",@"#####",logContent,@"#####"];
NSLog(@"%@",logContent);
});
}else{
NSString *newFrt = [@"[文件名:%s]
 [函数名:%s]
 [行号:%d]
" stringByAppendingString:fmt ];
NSString *logContent = [NSString stringWithFormat:newFrt,__FILE__, __FUNCTION__, __LINE__,##__VA_ARGS__];
logContent = [NSString stringWithFormat:@"%@%@%@",@"#####",logContent,@"#####"];
NSLog(@"%@",logContent);
}

#else
#define CCDebugLog(fmt,...)
# endif

替换系统NSLog

#ifdef DEBUG
#define NSLog(format, ...) printf("
[%s] %s [第%d行] %s
", __TIME__, __FUNCTION__, __LINE__, [[NSString stringWithFormat:format, ## __VA_ARGS__] UTF8String]);
#else
#define NSLog(format, ...)
#endif
