ios 获取数据判断为空

第一种

//            if ([response[@"data"]objectForKey:@"findGoodGoods"] != nil && ![[response[@"data"]objectForKey:@"findGoodGoods"] isKindOfClass:[NSNull class]] ){

//                for(NSDictionary *dict in [response[@"data"]objectForKey:@"findGoodGoods"]){

//                    FH_QZNewListModel *model = [FH_QZNewListModel mj_objectWithKeyValues:dict];

//                    [findGoodGoods addObject:model];

//                }

//            }

第二种

            if([selfisNotNULL:[response[@"data"]objectForKey:@"findGoodGoods"]]) {

                for(NSDictionary*dictin[response[@"data"]objectForKey:@"findGoodGoods"]){

                    FH_QZNewListModel *model = [FH_QZNewListModel mj_objectWithKeyValues:dict];

                    [findGoodGoodsaddObject:model];

                }

            }

- (BOOL)isNotNULL:(id)obj{

    return  NULL!=obj &&nil!=obj && (NULL)!=obj && (Nil)!=obj  && [NSNullnull]!=obj ?  YES:NO;

}

第三种

findGoodGoods =[FH_QZNewListModel mj_objectArrayWithKeyValuesArray:[response[@"data"]objectForKey:@"findGoodGoods"]];
