Answer 1

使用此代码并根据您的要求进行更改

    NSMutableDictionery * repsonseDict = [[NSMutableDictionery alloc]init];
    repsonseDict =  [reponseObj objectForKey@"response"];

    NSArray * allKeys = [repsonseDict allKeys];

    NSMutableArray * emailArr = [[NSMutableArray alloc]init];

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

      NSString * numberKey = [NSString stringWithFormat:@"%d",i];

     [emailArr addObject:[[repsonseDict objectForKey:numberKey]objectForKey:@"email"]];
    }
