ios - 从服务 Objective c 获取数据

Question

我在使用以下服务数据时遇到了一个小问题

{
    "DataTable": {
        "DataList1": {

            "StudentName": "Rakesh",
            "StudentId": "13",
            "StudentAge": "19",
            "StudentAddress": "NewYork",
        },
        "DataList2": [{
            "TeacherName": "Abhinav",
            "TeacherId": "309",
            "TeacherAge": "34",
            "TeacherAddress": "NewYork",
        }]
    }
}

我可以从DataList1 中获取数据，但不知道如何从DataList2 中获取数据。以下是我尝试过的代码。请帮助找出解决方案。提前致谢

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    [jsonArray removeAllObjects];
    NSString *responseString = [[NSString alloc] initWithData:self.responseData encoding:NSUTF8StringEncoding];
    self.responseData = nil;

    NSMutableDictionary *sdf = [(NSDictionary*)[responseString JSONValue] objectForKey:@"DataTable"];
    NSMutableArray * myArray = [[NSMutableArray alloc] init];

    if (([(NSString*)sdf isEqual: [NSNull null]])) {
        UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Information" message:@"Currently there are no Data" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert setTag:1];
        [alert show];
    }else {

        [myArray addObject:[sdf objectForKey:@"DataList1"]];

        jsonArray=[myArray mutableCopy];
        refilldict=[jsonArray objectAtIndex:0];
        NSArray *keys = [refilldict allKeys];
        for(int p=0 ; p<[keys count]; p++ )
        {
            NSString *value=[refilldict objectForKey:[keys objectAtIndex:p]];
            if ([value isEqual: [NSNull null]]||[value length]==0) {

                [refilldict setValue:@"" forKey:[keys objectAtIndex:p]];

            }

        }
 lblStudentName.text = [refilldict objectForKey:@"StudentName"];
        lblStudentId.text = [refilldict objectForKey:@"StudentId"];
        lblStudentAge.text = [refilldict objectForKey:@"StudentAge"];

        lblStudentAddress.text = [refilldict objectForKey:@"StudentAddress"];
}
 self.navigationController.navigationBar.userInteractionEnabled = YES;
    [HUD hide:YES];
    [HUD removeFromSuperview];
    HUD=nil;

}

请使用下面的代码并在其中传递您的 Initial Json 字典。

-(void)parseJsonData:(NSDictionary *)jsonDictionary{

    for(int i=0;i<[jsonDictionary allKeys].count;i++){

        NSString *keyName = [[jsonDictionary allKeys] objectAtIndex:i];
        id objValue = [jsonDictionary objectForKey:keyName];

        if([objValue isKindOfClass:[NSArray class]]){

            NSArray *dataList2Array = (NSArray *)objValue;
            NSLog(@"DataList2 Is :--%@",dataList2Array);
        }
        else {

            NSDictionary *dataList1 = (NSDictionary *)objValue;
            NSLog(@"DataList1 Is :--%@",dataList1);
        }
    }
}
