Change Action sheet popover arrow in iOS8

Question

i\'m using UIAlertController . But on iPad with iOS 8, actionSheet show with popover arrow. Any ideas to hide that arrow?

Here is my code:

The selected answer does not center the alert if you have a nav/status bar. To exactly center your alert controller:

alertController.popoverPresentationController.sourceRect = [self sourceRectForCenteredAlertController];
alertController.popoverPresentationController.sourceView = self.view;
alertController.popoverPresentationController.permittedArrowDirections = 0;

With the convenience method:

- (CGRect)sourceRectForCenteredAlertController
{
    CGRect sourceRect = CGRectZero;
    sourceRect.origin.x = CGRectGetMidX(self.view.bounds)-self.view.frame.origin.x/2.0;
    sourceRect.origin.y = CGRectGetMidY(self.view.bounds)-self.view.frame.origin.y/2.0;
    return sourceRect;
}

Also, the alert controller does not stay centered if the view is rotated. To keep the alert controller centered you need to update the sourceRect after rotation. For example:

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    // Check if your alert controller is still being presented
    if (alertController.presentingViewController) {
        alertController.popoverPresentationController.sourceRect = [self sourceRectForCenteredAlertController];
    }
}

Or, if you do not want to use rotation events, you can use the popoverPresentationController delegate method to reposition the popover:

- (void)popoverPresentationController:(UIPopoverPresentationController *)popoverPresentationController willRepositionPopoverToRect:(inout CGRect *)rect inView:(inout UIView *__autoreleasing  _Nonnull *)view
{ 
    // Re-center with new rect
}
