/* 用法 TICK do your work here TOCK */ #define TICK NSDate *startTime = [NSDate date]; #define TOCK NSLog(@"Time:%f", -[startTime timeIntervalSinceNow]);
12.机型的判断
/* 判断是否为iPhone */ #define isiPhone (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) /* 判断是否是iPad */ #define isiPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) /* 判断是否为iPod */ #define isiPod ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])
13.由角度转换弧度 由弧度转换角度
degree角度 radian 弧度 角度转弧度 #define LRDegreesToRadian(angle) (M_PI * (angle) / 180.0) 弧度转角度 #define LRRadianToDegrees(radian) (radian*180.0)/(M_PI)
14.弱引用
#define JKWeakSelf __weak typeof(self) weakSelf = self;
15.打印函数，可以打印所在的函数，行数，以及你要打印的值
#define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__); NSLog(@"==1==%s 2==[Line %d] 3==%@", __PRETTY_FUNCTION__, __LINE__,string);
16.设置 view 圆角和边框
#define LRViewBorderRadius(View, Radius, Width, Color)\ \ [View.layer setCornerRadius:(Radius)];\ [View.layer setMasksToBounds:YES];\ [View.layer setBorderWidth:(Width)];\ [View.layer setBorderColor:[Color CGColor]]
17.宏定义一个弹窗方法,括号里面是方法的参数
#define JKShowAlert(message) UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"温馨提示" message:message delegate:self cancelButtonTitle:@"cancel" otherButtonTitles: @"OK"];[alert show];
18.为空的判断
字符串是否为空 #define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO ) 数组是否为空 #define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0) 字典是否为空 #define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0) 是否是空对象 #define kObjectIsEmpty(_object) (_object == nil \ || [_object isKindOfClass:[NSNull class]] \ || ([_object respondsToSelector:@selector(length)] && [(NSData *)_object length] == 0) \ || ([_object respondsToSelector:@selector(count)] && [(NSArray *)_object count] == 0))
19.APP版本号
#define kAppVersion [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]
20.系统版本号
#define kSystemVersion [[UIDevice currentDevice] systemVersion]
21.获取t路径

22.获取一段时间间隔
#define kStartTime CFAbsoluteTime start = CFAbsoluteTimeGetCurrent(); #define kEndTime NSLog(@"Time: %f", CFAbsoluteTimeGetCurrent() - start)
23.方正黑体简体字体定义
#define FONT(F) [UIFont fontWithName:@"FZHTJW--GB1-0" size:F]
24.程序的本地化,引用国际化的文件
#define MyLocal(x, ...) NSLocalizedString(x, nil)
25.单例化一个类
#define SYNTHESIZE_SINGLETON_FOR_CLASS(classname) \ \ static classname *shared##classname = nil; \ \ + (classname *)shared##classname \ { \ @synchronized(self) \ { \ if (shared##classname == nil) \ { \ shared##classname = ［self alloc] init]; \ } \ } \ \ return shared##classname; \ } \ \ + (id)allocWithZone:(NSZone *)zone \ { \ @synchronized(self) \ { \ if (shared##classname == nil) \ { \ shared##classname = [super allocWithZone:zone]; \ return shared##classname; \ } \ } \ \ return nil; \ } \ \ - (id)copyWithZone:(NSZone *)zone \ { \ return self; \ } #endif
26.判断是真机还是模拟器
\#if TARGET_OS_IPHONE //真机 \#endif \#if TARGET_IPHONE_SIMULATOR //模拟器 \#endif
27.在OC文件导入某些头文件
#ifdef __OBJC__ //导入头文件 #endif
28.首次启动判断
#define First_Launched @"firstLaunch"
29.GCD 的宏定义
//GCD - 一次性执行 #define kDISPATCH_ONCE_BLOCK(onceBlock) static dispatch_once_t onceToken; dispatch_once(&onceToken, onceBlock); //GCD - 在Main线程上运行 #define kDISPATCH_MAIN_THREAD(mainQueueBlock) dispatch_async(dispatch_get_main_queue(), mainQueueBlock); //GCD - 开启异步线程 #define kDISPATCH_GLOBAL_QUEUE_DEFAULT(globalQueueBlock) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), globalQueueBlocl);
