NSJSONSerializationNSError *jsonParsingError = nil;
NSDictionary *parsedJson = [NSJSONSerialization JSONObjectWithData:response options:0 error:&jsonParsingError];
[parsedJson objectForKey:@"resultCount"];
更新： 在json字符串中，结果是一个数组。所以在序列化之后，您将得到一个字典数组。因此，要获得类似“amgartid”的属性，首先必须从字典中获取结果键的值，该字典将有一个（字典）数组。然后，您可以使用索引将该数组或访问循环到各个字典
NSArray *results = [parsedJson objectForKey:@"results"];
NSString *amgArtistId = [[results firstObject] objectForKey:@"amgArtistId"];
这样，您也可以获得其他元素。您不必为此序列化每个元素。序列化json字符串一次就足够了。谢谢。但是我如何在单独的数组/字典中收集“结果”的数据呢？我是否需要传递单个密钥，如“amgarstid”、“artistId”等？我需要在集合中解析完整的数据，以便我可以在“UITableView”上显示相同的数据可能的副本
