Ios NSJSONSerialization解析数据问题

我正在分析以下数据：-

NSURL *URL = [NSURL URLWithString:@"http://maps.googleapis.com/maps/api/directions/json?origin=40.714353,-74.005973&destination=40.650000,-73.950000&sensor=false&units=metric&mode=transit&departure_time=1396594530&alternatives=true"];
NSData* data = [NSData dataWithContentsOfURL:URL];
NSDictionary *dataDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];

仅部分结果而非全部结果显示：

我认为try sensor=True。我认为这是个问题。同一个问题，我试过了。我认为try sensor=True。我认为这是个问题。同一个问题，我试过了。你是怎么知道的？谷歌提供了你是怎么知道的？谷歌提供了
