UIAlertController从UIBarButtonItem呈现,旋转后位置错误

Question

我有UIToolBar一些按钮.我目前UIAlertController使用UIAlertControllerStyleActionSheet该按钮的演讲风格.它显示正确,但是当我旋转设备时,此操作表有错误的位置.

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];

UIAlertAction* destructive = [UIAlertAction actionWithTitle:destructiveTitle style:UIAlertActionStyleDestructive handler:someHandler];
[alertController addAction:destructive];

[alertController setModalPresentationStyle:UIModalPresentationPopover];
alertController.modalInPopover = YES;

alertController.popoverPresentationController.barButtonItem = barButton;

alertController.popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirectionAny;

alertController.popoverPresentationController.delegate = self;

[self presentViewController:alertController animated:YES completion:nil];

还有一两件事在这里,popoverPresentationController:willRepositionPopoverToRect从UIPopoverPresentationControllerDelegate没有叫我时,旋转装置.

这里出了什么问题,有什么建议吗？

提前致谢!
