#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))
