How to make UIPopoverController keep same position after rotating?

Question

I can\'t keep popover the same position on the screen after rotation. Is there any good way to do that, because just setting some frame to popover works terrible after rotating.

As of iOS 8.0.2 willRotateToInterfaceOrientation will not have any effect. As mhrrt mentioned, you need to use the delegate method:

- (void)popoverController:(UIPopoverController *)popoverController willRepositionPopoverToRect:(inout CGRect *)rect inView:(inout UIView *__autoreleasing *)view

So for example if you want your popover to appear directly below a button that was pressed, you would use the following code:

- (void)popoverController:(UIPopoverController *)popoverController willRepositionPopoverToRect:(inout CGRect *)rect inView:(inout UIView *__autoreleasing *)view
{
   CGRect rectInView = [self.theButton convertRect:self.theButton.frame toView:self.view];
   *rect = CGRectMake(CGRectGetMidX(rectInView), CGRectGetMaxY(rectInView), 1, 1);
   *view = self.view;
}
