去除服务器返回值里面的长度为零的空字符串

//调用方法
   if ([responseObject isKindOfClass:[NSDictionary class]]) {

    responseObject =   [[NetWorkManager sharedManager] removeEmptyStrAtDictionary:responseObject];

    }




//字典里去除空
- (id)removeEmptyStrAtDictionary:(id)dict {
    
    
    //空字符串直接不要
    if ([dict isKindOfClass:[NSDictionary class]]) {

            __strong __typeof(self) strongSelf = weakSelf;
            
            
            if ([obj isKindOfClass:[NSString class]] && ((NSString*)obj).length <= 0 ) {
