问题
I'm looking to present a UIPopoverController from a button on a UICollectionViewCell.
So far, everything is created ok, but the popover isn't visible.
Is there a special way of doing this?
The code works if I display it from anything else other than a collection view cell.
The following code is in the UICollectionViewCell subclass.
if (_infoPopover == nil) {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
GameInfoViewController *gameInfoVC = (GameInfoViewController *)[storyboard instantiateViewControllerWithIdentifier:@"GameInfoViewController_ID"];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:gameInfoVC];
_infoPopover = popover;
[gameInfoVC setGameNameString:_gameNameLabel.attributedText];
}
[_infoPopover presentPopoverFromRect:_infoButton.frame inView:self permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Thanks!

Perform PopOver from UIViewController, not in UICollectionViewCell. So, use delegate to control.
//Cell.m
-(void)popOVerClick:(UIButton *)button{
[[self delegate] didPopOverClickInCell:self];
}
implement protocol
//ViewController
-(void)didPopOverClickInCell:(MyCell *)cell{
if ([self.flipsidePopoverController isPopoverVisible]) {
[self.flipsidePopoverController dismissPopoverAnimated:YES];
} else {
FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideViewController" bundle:nil];
controller.label.text = cell.title;
controller.delegate = self;
self.flipsidePopoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
[self.flipsidePopoverController presentPopoverFromRect:cell.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}

change inView to collectionView
[_infoPopover presentPopoverFromRect:_infoButton.frame inView:self.collectionView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
