ios - 从服务中获取值

Question

我是 Service Responses 的新手。我无法区分 “First Class” 和 “Second Class” 到一个单独的array.also 从这个响应我需要第一类作为数组和第二类作为数组。在第一个类中，我需要获取 class_id 和 class_name 作为字符串。它将持续到 15 个类。我如何确定响应是否是 first class 还是 second class 还是其他类(class)？长期挣扎。提前致谢。

Response :{
"First Class" =     (
            {
        "class_id" = 2;
        "class_name" = "Art";
            },{
        "class_id" = 2;
        "class_name" = "Medical";
            }
        );
   "Second Class" =   (
            {
        "class_id" = 3;
        "class_name" = "Swim";
            }
        )
}

试试这个。

根据您的代码，您的服务响应是字典。 注意:假设 responseDictionary 您的服务响应。

如果您的响应有 'n' 个类别，则像这样分隔每个类别

//get individual classes like this

for(int i=0;i<[[responseDictionary allKeys]count];i++)
{
    NSArray *class = [responseDictionary objectForKey:[[responseDictionary allKeys]objectAtIndex:i]];
}

然后

for(NSDictionary *individualDict in individualClassArray)
{
    NSString *classID = [NSString stringWithFormat:@"%@",[individualDict objectForKey:@"class_id"]];
    NSString *className = [NSString stringWithFormat:@"%@",[individualDict objectForKey:@"class_name"]];
    NSLog(@"class id %@",classID);
    NSLog(@"class name %@", className);
}
