用NSJSONSerialization自己构造WebService的Json响应包

Nsstring *sampleData = @"{\"id\":1,\"name\":\"NickName\",\"sex\":\"Male\",\"PhoneNo\":18818157583,\"comment\":\"Thisiscomment\",\"profile\":\"nothing is impossible\"}";

NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:[sampleData dataUsingEncoding:NSUTF8StringEncoding] options:(NSJSONReadingMutableContainers) error:nil];

CustomModel *model = [ [CustomModel alloc] initWithDict: dict];
