滚动视图中的弹出窗口

发布于 2024-11-07 04:34:09 字数 709 浏览 0 评论 0原文

在我的 iPad 应用程序中，我在滚动视图中使用带有箭头的弹出框。它工作正常，但是当我滚动视图，然后点击按钮时，带有箭头的弹出窗口不会跟随按钮，它会在其原始位置打开。

我使用这段代码：

(void)showHomePopupAction:(id)sender {     
   self.popHome = [[[PopHome alloc] initWithNibName:@"PopHome" bundle:[NSBundle mainBundle]] autorelease];
   popHome.contentSizeForViewInPopover = CGSizeMake(popHome.view.frame.size.width, popHome.view.frame.size.height);
   self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:popHome] autorelease];
   [self.popoverController presentPopoverFromRect:popoverButtonForHome.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];     
}

您有任何想法或建议来解决这个问题吗？谢谢！

In my iPad App, I use a popover with an arrow on a button in a scroll view. It works fine but when I scroll the view, then tap on the button, the popover with the arrow doesn't follow the buttom, it opens at its original position.

I use this code:

(void)showHomePopupAction:(id)sender {     
   self.popHome = [[[PopHome alloc] initWithNibName:@"PopHome" bundle:[NSBundle mainBundle]] autorelease];
   popHome.contentSizeForViewInPopover = CGSizeMake(popHome.view.frame.size.width, popHome.view.frame.size.height);
   self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:popHome] autorelease];
   [self.popoverController presentPopoverFromRect:popoverButtonForHome.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];     
}

Do you have any idea or suggestion to fix this problem?
Thanks!

嘿，尝试这样的事情：

- (void)showHomePopupAction:(id)sender {     
       self.popHome = [[[PopHome alloc] initWithNibName:@"PopHome" bundle:[NSBundle mainBundle]] autorelease];
       popHome.contentSizeForViewInPopover = CGSizeMake(popHome.view.frame.size.width, popHome.view.frame.size.height);
       self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:popHome] autorelease];
       CGRect frame = popoverButtonForHome.frame;
       frame.origin.y -= self.scrollView.bounds.origin.y; // you can postion the popover with + and - values
       [self.popoverController presentPopoverFromRect:frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}

我只需要完全相同的...代码适用于 uiscrollview 中的 uibutton。

Hey, try something like this:

- (void)showHomePopupAction:(id)sender {     
       self.popHome = [[[PopHome alloc] initWithNibName:@"PopHome" bundle:[NSBundle mainBundle]] autorelease];
       popHome.contentSizeForViewInPopover = CGSizeMake(popHome.view.frame.size.width, popHome.view.frame.size.height);
       self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:popHome] autorelease];
       CGRect frame = popoverButtonForHome.frame;
       frame.origin.y -= self.scrollView.bounds.origin.y; // you can postion the popover with + and - values
       [self.popoverController presentPopoverFromRect:frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}

I just needed exactely the same ... the code works for my uibutton in a uiscrollview.
