UIActionSheet iOS 8 error - ios

Question

I'm trying to show UIActionSheet on iPad from button on UITableViewCell. It works fine on iOS 7, but not working properly on iOS 8. UIActionSheet containts some visual artifacts and I'm getting this warning in console:
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x79793de0 H:[UIView:0x797a7630(304)]>",
"<NSLayoutConstraint:0x7a16ae00 UIView:0x7a16ab60.width == _UIAlertControllerView:0x797a9230.width>",
"<NSAutoresizingMaskLayoutConstraint:0x7a66f2a0 h=--& v=--& H:[UIView:0x7a16ab60(298)]>",
"<NSLayoutConstraint:0x797a49e0 _UIAlertControllerView:0x797a9230.width >= UIView:0x797a7630.width>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x79793de0 H:[UIView:0x797a7630(304)]>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
My code:
- (void)onFavoriteBtn:(id)sender {
CGPoint btnPosition = [sender convertPoint:CGPointZero toView:_tableView];
NSIndexPath *indexPath = [_tableView indexPathForRowAtPoint:btnPosition];
if (indexPath) {
UIButton *favoriteBtn = (UIButton *)sender;
CGRect favoriteBtnRect = favoriteBtn.frame;
UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Remove from Favorites" otherButtonTitles:nil];
[sheet showFromRect:favoriteBtnRect inView:favoriteBtn.superview animated:true];
}
}

UIActionSheet is deprecated, so you can use UIAlertViewController available in iOS 8.0 or later.
- (IBAction)onFavoriteBtn:(id)sender {
CGPoint btnPosition = [sender convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:btnPosition];
if (indexPath) {
[self showActionSheet:sender];
}
}
- (void)showActionSheet:(UIView *)sender
{
NSString *alertTitle = NSLocalizedString(#"ActionTitle", #"Archive or Delete Data");
NSString *alertMessage = NSLocalizedString(#"ActionMessage", #"Deleted data cannot be undone");
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:alertTitle
message:alertMessage
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:NSLocalizedString(#"Cancel", #"Cancel action")
style:UIAlertActionStyleCancel
handler:^(UIAlertAction *action)
{
NSLog(#"Cancel action");
}];
UIAlertAction *deleteAction = [UIAlertAction actionWithTitle:NSLocalizedString(#"Delete", #"Delete action")
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction *action)
{
NSLog(#"Delete action");
}];
UIAlertAction *archiveAction = [UIAlertAction actionWithTitle:NSLocalizedString(#"Archive", #"Archive action")
style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action)
{
NSLog(#"Archive action");
}];
[alertController addAction:cancelAction];
[alertController addAction:deleteAction];
[alertController addAction:archiveAction];
UIPopoverPresentationController *popover = alertController.popoverPresentationController;
if (popover)
{
popover.sourceView = sender;
popover.sourceRect = sender.bounds;
popover.permittedArrowDirections = UIPopoverArrowDirectionAny;
}
[self presentViewController:alertController animated:YES completion:nil];
}

Looks like your favorite button superview is too small to embed action sheet. Try to use window to display action sheet, just don't forget convert coordinates of favorites button:
- (void)onFavoriteBtn:(id)sender {
CGPoint btnPosition = [sender convertPoint:CGPointZero toView:_tableView];
NSIndexPath *indexPath = [_tableView indexPathForRowAtPoint:btnPosition];
if (indexPath) {
UIButton *favoriteBtn = (UIButton *)sender;
CGRect frame = [self.window convertRect:favoriteBtn.bounds fromView:favoriteBtn];
UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Remove from Favorites" otherButtonTitles:nil];
[sheet showFromRect:frame inView:self.window animated:true];
}
}
