我已将 Google maps sdk for ios 添加到我的 Iphone 应用程序中，如果单击的信息窗口弹出标题，我有一些自定义标记，我如何在此信息窗口中添加一个按钮，以便如果按下将转到新页面？现在我尝试使用这篇文章来解决这个问题在 Google Maps SDK for native iOS/objective C 中的 InfoWindow/Marker 上添加 Click Event它不会给我错误，但它不会工作。
这就是我想要的结果：http ://www.flickr.com/photos/74719051@N05/6728157477/
您链接的问题的答案显示了使用 MapKit 的代码，因此它不适用于 iOS 版 Google Maps SDK。
请参阅此问题以了解如何使用适用于 iOS 的 Google Maps SDK 返回自定义视图：
但是请注意，根据这个问题，看起来显示的内容可能是视图的视觉副本而不是实际视图，这可能会限制您可以与视图进行的交互：
添加按钮以查看由 markerInfoWindow 委托方法返回的视图
不过应该可以简单地检测信息窗口上的点击并转到不同的页面didTapWindowOfMarker。
请注意，Google 的问题跟踪器中有一个功能请求来添加对此的直接支持：

这段代码完全符合您的要求。它的灵感来自 Saxon Druce 推荐的链接中的 #9，但做得不同且更完整。它检测到点击添加到我的自定义信息窗口的按钮。我创建了一个带有 2 个假按钮的自定义 infoWindow（它们实际上可以被图像替换，因为它们无论如何都不会触发任何操作），并且我在 infoWindow 上添加了一个带有 2 个真实但透明的按钮的透明 UIView。这些按钮将触发动作。
最后，我使用了一些委托方法或 KVC，以便在 infoWindow 本身移动时移动覆盖的 UIView。

1) 创建一个要在 infoWindow 中显示的子视图。2）设置子视图的框架等于infoWindow视图的框架。
subView = [[[NSBundle mainBundle] loadNibNamed:@"viewName" owner:self options:nil] objectAtIndex:0];
[subView setFrame:infoview.frame];
[self.mapview addSubview:subView];
