我在我的应用程序中使用最新的 GoogleMaps iOS SDK,在最新的 iOS 更新 7.0.3 之后,它在第一次触摸后开始变得无响应。让我对此进行扩展。第一次触摸地图后,地图变得无响应。起初,您可以捏缩放、拖动、滑动和其他所有操作,但在第一次触摸之后,它就不再起作用了。这在 Apple 更新他们的 iOS 之后开始发生。如果我使用 iOS6 模拟器,即使在第一次触摸之后,我也可以完成所有手势。我不知道这是因为 iOS 更新还是我的代码有问题。如果有人有任何建议或经历过类似的事情可以指导我,那将不胜感激。提前致谢。
它适用于iOS6,之前也适用于iOS7。MapsViewController.m
