在我开始之前只有几点：我刚刚接管了这段代码我对 iOS 代码几乎没有经验认为我是一个菜鸟，所以对我来说放轻松：P
我在下面有一些代码，用于显示UIActionSheet. 在 iOS 8 中 UIActionSheet 已被删除（感谢苹果！）所以我开始改变它来使用UIAlertController......我遇到了很多我已经解决的问题，现在我完全困惑了，需要你们有经验的帮助......！
这是一个截图
现在您可以看到UIAlertController正在显示，但 UIView 的位置不正确，因此无法使用控件！您可以按预期拖动数字，但这并不容易......
如您所见，共有三个控制器，一个用于选择日期时间，一个用于乘客数量，另一个用于选择车辆类型。
我只需要一个可以在所有 iOS8 手机上运行的简单的修复程序，它可能有点狡猾，因为我们正要雇人重新编写整个代码，因为代码总体上很糟糕，我们想从自下而上。
如果您想了解更多信息，请告诉我，我的 iOS 编码经验非常少（我确实想学习，因为我喜欢它，尽管不如 Android）
