如何使用NSJSONSerialization解析此数据？
答案 0 :(得分：1)
NSError *jsonParsingError = nil;
NSDictionary *parsedJson = [NSJSONSerialization JSONObjectWithData:response options:0 error:&jsonParsingError];
现在，您可以使用json响应中的键来访问json元素。 例如，要计算结果。
[parsedJson objectForKey:@"resultCount"];
<强>更新 在你的json字符串中，结果是一个数组。所以在序列化后你会得到一系列字典。因此，要获得像'amgArtistId'这样的属性，首先必须从字典中获取结果键的值，该字典将包含一个（字典）数组。然后，您可以使用索引循环该数组或访问单个词典。
NSArray *results = [parsedJson objectForKey:@"results"];
NSString *amgArtistId = [[results firstObject] objectForKey:@"amgArtistId"];
这样你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字符串就足够了。
