iPad 中 PopoverView 中的 UIDatePicker
我有一个运行 iOS 3.2.2 的 iPad 特定应用程序，它在 ui 弹出窗口中显示设置视图。这一切都渲染得很好，但现在我试图让一个日期选择器在视图内渲染，但不确定显示它的最佳方法是什么。
现在它有一个按钮可以切换模式中日期选择器的可见性，但与操作表的正常方法相比，这对于管理解雇来说似乎非常笨拙。
我无法找到针对这种情况的“最佳实践”，并且想知道是否有人以前遇到过这种情况并可以提供一些建议或指导。
谢谢！
I have an iPad specific application running iOS 3.2.2 which displays a settings view in a ui popover. This all renders great, but now I'm trying to get a date picker to render inside the view and not sure what the best approach is for displaying it.
Right now it has a button which toggles visibility of the date picker within the modal, but that seems very clumsy for managing dismissal compared to the normal approach of an action sheet.
I haven't been able to find a 'best practice' for this situation and was wondering if anyone's run into this before and could offer some suggestions or guidance.
Thanks!

请注意此处的答案，表明 UIPickerView 在弹出窗口中呈现时必须是控制器的根视图。听起来您可能正在尝试将日期选择器放置为弹出窗口内的多个视图之一。如果是这样，您将遇到此处描述的问题。

Note the answer here indicating that the UIPickerView must be the root view of your controller when presented in a popover. It sounds like you may be attempting to place the date picker as one of several views inside the popover. If so, you'll encounter the problem described here.
