我遇到了错误

我在这里循环.从Json中的数组到我的模型任务列表然后存储到NSMutableArray _tasklist

NSArray *taskJson = [json objectForKey:@"fOTaskListModelWss"];

    for (NSDictionary *dictCQ in taskJson) {
        NSLog(@"TASKLIST: %@", [dictCQ objectForKey:@"foTaskListModelWs"]);

        NSDictionary *datadic = [dictCQ objectForKey:@"foTaskListModelWs"];
        TaskList *task = [[TaskList alloc]init];
        [task setTaskCount:datadic[@"count"]];
        [task setFuncCd:datadic[@"funcCd"]];
        [task setFuncCdDscp:datadic[@"funcCdDscp"]];
        [task setRequestStatus:datadic[@"requestStatus"]];
        [task setRole:datadic[@"role"]];
        [_taskList …

我使用此链接作为指南,但我可以弄清楚如何使用AND子句进行解析.它只在示例代码中定义OR子句.

如果我要从SQL语句转换它,它看起来像这样......

SELECT * FROM RemittanceTable WHERE beneCode = 'code' AND remittanceAmount = 500.00

例如,在此代码中,我想在读取数据之前检查代码和数量是否正确.但它用OR子句验证

PFQuery *beneCodeQuery = [PFQuery queryWithClassName:@"RemittanceTable"];
[beneCodeQuery whereKey:@"beneCode" containsString:_beneCodeText.text];

PFQuery *amountQuery = [PFQuery queryWithClassName:@"RemittanceTable"];
[amountQuery whereKey:@"remittanceAmount" equalTo:amount];

PFQuery *query = [PFQuery orQueryWithSubqueries:[NSArray arrayWithObjects:beneCodeQuery,amountQuery,nil]];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (!error) {
        for (PFObject *object in objects) {
            NSLog(@"%@", object);

            [self resignAllResponder];
            _paymentDetailsImage.frame = CGRectMake(_paymentDetailsImage.frame.origin.x, _paymentDetailsImage.frame.origin.y, _paymentDetailsImage.frame.size.width, paymentModeOrigHeight);
            _detailsView.alpha = 1;

        }
    }}}];
