ActionSheet源视图BarButtonItem

Question

我在导航栏中有一个条形按钮项,按下时将显示一个UIAlertController样式为.ActionSheet.在iPhone中,它看起来就像我想要的那样.对于iPad,我知道我需要添加

// For iPad, set the pop over bounds
var popOver = optionMenu.popoverPresentationController
popOver?.sourceView = button as UIView
popOver?.sourceRect = (button as UIView).bounds
popOver?.permittedArrowDirections = UIPopoverArrowDirection.Any

有没有人知道如何使用条形按钮项目作为sourceView和sourceRect？我希望popover指向bar按钮项.

Answer 1

只是用 popOver?.barButtonItem = myBarButtonItem
