    总结了iOS开发过程中的一些常用宏,以后会陆陆续续添加进来。

    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)
