ios - 如何在iOS中解析这种json字符串

Question

您好我是ios编程和学习的新手，我正在通过json格式进行网络服务调用和获取响应。我成功了这一点，但我不知道如何获取(解析)响应并遍历响应。我的响应是下面，我的字典如下:
json

 **code**

 NSString *mydata = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];

    NSLog(@"====My data from webservice is===%@",mydata);


     NSError *e = nil;
    //saving data in dictionary.
    NSDictionary *recipeDictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&e];
        NSLog(@"My Dictionary is %@", recipeDictionary);

很简单。

根据您的回复，确认您的回复是一个字典。在您的cipictionDictionary中，有一个与联系人键关联的数组对象。

所以把这个值放在数组中。

 NSArray *yourContactsArray = [recipeDictionary valueForKey:@"contacts"];

现在这个数组包含字典形式的多个对象。我正在打印名称键中的所有值以演示如何获取。

for (NSDictionary *dict in yourContactsArray)
{
     NSString *name = [dict valueForKey:@"name"];
     NSLog(@"%@",name);
}
