大家都是知道使用宏不仅方便，而且可以提高开发效率。下面总结了iOS开发过程中的一些常用宏，会持续的往里面添加。

Objective-C

//字符串是否为空
#definekStringIsEmpty(str)([strisKindOfClass:[NSNullclass]]||str==nil||[strlength]<1?YES:NO)

//是否是空对象
#definekObjectIsEmpty(_object)(_object==nil\
||[_objectisKindOfClass:[NSNullclass]]\
||([_objectrespondsToSelector:@selector(length)]&&[(NSData*)_objectlength]==0)\
||([_objectrespondsToSelector:@selector(count)]&&[(NSArray*)_objectcount]==0))

还有很多其他类型的宏，此处不一一列举

创建一个import所有宏相关的文件Macros.h

Macros.h
#import"UtilsMacros.h"
#import"APIStringMacros.h"
#import"DimensMacros.h"
#import"NotificationMacros.h"
#import"SharePlatformMacros.h"
#import"StringMacros.h"
#import"UserBehaviorMacros.h"
#import"PathMacros.h"
在xcode项目的pch文件中，导入Macros.h文件

XcodeProjectName-Prefix.pch
#ifdef__OBJC__
#import<UIKit/UIKit.h>
#import<Foundation/Foundation.h>
#import"Macros.h"
#endif
