在iOS8中显示带有UIActionSheet的UIPickerView无法正常工作 [英] Showing a UIPickerView with UIActionSheet in iOS8 not working

问题描述

在 iOS8 无效

该代码适用于 iOS7 ，但不适用于 iOS8 。我确定这是因为UIActionSheet在 iOS8 中已被弃用，Apple建议使用 UIAlertController 。

The code works in iOS7, however it is not working in iOS8. I'm sure it is because UIActionSheet is deprecated in iOS8 and Apple recommends to use UIAlertController.

但是，如何在 iOS8 中执行此操作？我应该使用 UIAlertController ？

However, how to do it in iOS8? I should use UIAlertController?

推荐答案

来自UIActionSheet的参考资料：

From the reference for UIActionSheet:

UIActionSheet不是为子类设计的，也不应该为其层次结构添加视图。如果您需要提供比UIActionSheet API提供的更多自定义的工作表，您可以创建自己的工作表并使用presentViewController以模态方式呈现它：animated：completion：。

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

我的猜测是你看到的确切原因。

My guess is your seeing exactly why.

UIAlertController的参考没有类似的免责声明，但看看它的界面，我的猜测Apple会在发布之前添加它。

The reference for UIAlertController doesn't have a similar disclaimer, but looking at its interface, my guess is Apple will add it before release.

我的建议是创建一个包含选择器和按钮的小视图，并根据需要显示和隐藏它。这并不难做到并且你没有推动界面超出其预期用途。

My recommendation would be to just create a small view containing your picker and buttons and show and hide it as needed. It's not that hard to do and your not pushing interfaces beyond their intended uses.
