如何使用NSJSONSerialization反序列化转义的JSON字符串？

如果您嵌套了JSON，则只需调用

JSONObjectWithData

NSString *string =  @""{ \"name\" : \"Bob\", \"age\" : 21 }"";// --> the string// "{ "name" : "Bob", "age" : 21 }"NSError *error;NSString *outerJson = [NSJSonSerialization JSONObjectWithdata:[string dataUsingEncoding:NSUTF8StringEncoding]        options:NSJSonReadingAllowFragments error:&error];// --> the string//  { "name" : "Bob", "age" : 21 }NSDictionary *innerJson = [NSJSonSerialization JSONObjectWithdata:[outerJson dataUsingEncoding:NSUTF8StringEncoding]        options:0 error:&error];// --> the dictionary// { age = 21; name = Bob; }
