Ios UIAlertController中的UIView

在开始之前，我只想说几点： 我刚刚接管了这个代码 我在iOS代码方面几乎没有经验 在这看来我是个疯子，所以对我来说轻松点：P/P> 下面我有一些代码，用于显示UIActionSheet。在iOS 8中，UIActionSheet已被删除，感谢苹果！所以我已经开始改变一切，使用UIAlertController。。。 我遇到了很多我已经解决的问题，现在我完全糊涂了，需要你们这些有经验的人来帮助我

这是一个截图

现在您可以看到UIAlertController正在显示，但UIView位置不正确，因此无法使用这些控件！您可以按预期拖动数字，但这并不是那么容易

如您所见，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

我只需要一个很好的简单的修复程序，可以在所有iOS8手机上运行，它可能会有点不可靠，因为我们即将雇佣一个人来重新编写整个代码，因为代码总体上非常糟糕，我们希望从下到上重新设计应用程序

如果您想了解更多信息，请务必让我知道，我的iOS编码经验非常少，我很想学习，因为我很喜欢它，尽管没有Android那么多

我也在努力解决同样的问题。我需要在UIAlertController中有一个UIPickerView。经过几个小时的调查，我发现没有办法定制UIAlertController的视图。事实上，它明确地写在苹果的文档中

UIAlertController类旨在按原样使用，不支持子类化

此类的视图层次结构是私有的，不能修改

顺便说一句，您可以尝试其他解决方案-。
