从UICollectionViewCell呈现UIPopoverController

我希望通过UICollectionViewCell上的按钮呈现UIPopoverController。

到目前为止,所有内容都已创建,但弹出窗口不可见。

有没有一种特殊的方法呢?

如果我从集合视图单元格以外的任何其他位置显示代码,则代码可以正常工作。

以下代码位于UICollectionViewCell子类中。

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];

谢谢!

从UIViewController执行PopOver,而不是在UICollectionViewCell中执行。所以,使用委托来控制。

//Cell.m
-(void)popOVerClick:(UIButton *)button{
    [[self delegate] didPopOverClickInCell:self];
}

实施协议

//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];
    }
}

将inView更改为collectionView

[_ infoPopover presentPopoverFromRect:_infoButton.frame inView:self.collectionView allowedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
