点击折线没有任何作用 - 谷歌地图IOS SDK

>阅读过类似的帖子并尝试了他们的解决方案，但没有任何效果。通过XCode 6.x在IOS模拟器上运行超级简单的Google Maps SDK 1.9.x示例，当我点击(好吧，真的在模拟器中点击，这有什么不同吗？(没有记录任何内容，因为代码会让我相信它会，所以看起来确实TapOverlay永远不会被调用。

首先，如果您可以将相机启动到以下几点，则会更容易：

 GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:43.5157
                                                            longitude:-114.34367
                                                                 zoom:14];

因此，您可以在相机内轻松看到折线。

然后在ViewController.h头文件中，将接口更改为以下内容：

@interface ViewController : UIViewController<GMSMapViewDelegate>

因此，您的视图控制器将是 GMSMapViewDelegate。

最后，在您的self.view = mapView_;下方添加以下行：

mapView_.delegate = self;

此行将把你的视图控制器(即 GMSMapViewDelegate(分配给mapView_的 delgate，以便mapView_的委托将是 GMSMapViewDelegate，并且 didTapOverlay 方法将被调用。
