Objective c 如何在一个数组中获取此响应

这是我从web服务得到的响应。如何获取仅限城市的记录

  Data =     (
                    {
                Cities =             (
                                    {
                        CityCode = 21;
                        Name = Cork;
                        Numbers =                     (
                                                    {
                                Number = 2349990;
                                PauseOne = 3;
                                PauseTwo = 3;
                            }`enter code here`
                        );
                    }
    )

u hav发布的回复看起来像一本nsdictionary。没有服务器返回json。您可以发布服务器返回的确切json吗？提示：将nsdata转换为nsstring和post dat

此代码最终用于您：

NSMutableArray *arrFinalAllCities = [[NSMutableArray alloc]init];
    NSMutableArray *arrData = [responseObject objectForKey:@"Data"];
    for (int a=0; a<arrData.count; a++)
    {
        NSMutableArray *arrCity = [[arrData objectAtIndex:a] objectForKey:@"Cities"];
        for (int b=0; b<arrCity.count; b++)
        {
            [arrFinalAllCities addObject:[arrCity objectAtIndex:b]];
        }
    }
    NSLog(@"%@",arrFinalAllCities);

NSMutableArray*arrfinallallcities=[[NSMutableArray alloc]init]；
NSMutableArray*arrData=[responseObject objectForKey:@“Data”]；
对于（int a=0；a到目前为止，您的代码是什么？您确定这是一种有效的json格式吗？请检查问题，然后给出答案
NSMutableArray *arrFinalAllCities = [[NSMutableArray alloc]init];
    NSMutableArray *arrData = [responseObject objectForKey:@"Data"];
    for (int a=0; a<arrData.count; a++)
    {
        NSMutableArray *arrCity = [[arrData objectAtIndex:a] objectForKey:@"Cities"];
        for (int b=0; b<arrCity.count; b++)
        {
            [arrFinalAllCities addObject:[arrCity objectAtIndex:b]];
        }
    }
    NSLog(@"%@",arrFinalAllCities);
