/* 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]]

#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))

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);
