iphone - 从 contentViewController 中消除 UIPopOverController

Question

如何从 contentViewController 中消除弹出窗口，因此在下面的示例代码中，我想从 ProfileViewController 代码中消除 UIPopOver。我该怎么做呢？另一篇类似的文章建议使用 NSNotification，但如何使用它？

- (void)profilePop:(UITapGestureRecognizer *)recognizer
{
    ProfileViewController * profile = [[ProfileViewController alloc] init];
    CGPoint location = [recognizer locationInView:self.table];
    NSIndexPath* indexPath = [self.table indexPathForRowAtPoint:location];
    ConvoreCell* cell = (ConvoreCell *) [self.table cellForRowAtIndexPath:indexPath];
    profile.uid =  [[[self.posts objectAtIndex:indexPath.row] creator] mid];
    UIPopoverController * profilePop  = [[UIPopoverController alloc] initWithContentViewController:profile];
    [profilePop setPopoverContentSize:CGSizeMake(350, 180)];
    [profilePop presentPopoverFromRect:CGRectMake(0,0, cell.avatar.frame.size.width, cell.avatar.frame.size.height) inView:cell permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
}

我会在您的个人资料类中保留对弹出窗口的引用。

profile.popOver = profilePop;

然后在您想要关闭的区域中:

[self.popover dismissPopoverAnimated:YES];
