iPad UIPopoverController 不会越过 UITextView 中的 inputView
我正在尝试设置一个弹出窗口来指向视图中的 UIButton，该视图用作 UITextView 的“inputView”。我可以让一切正常工作，并且正确的数据将进入 UIPopoverController。但它表现出的行为不是我所期望的。这就是我所拥有的。以下方法编写在 UIView 子类中，该子类是 UITextView 的 inputView，也是按钮所在的视图。
- (IBAction)buttonTouchDown:(id)sender {
UIButton *button = (UIButton *)sender;
MyPopoverContentController *controller = [[MyPopoverContentController alloc] initWithNibName:@"MyNib" bundle:nil];
[controller setContentSizeForViewInPopover:CGSize(320.0, 304.0)];
self.popupController = [[UIPopupController all] initWithContentViewController:controller];
[self.popupController presentPopoverFromRect:[button frame] inView:self permittedArrowDirectoions:UIPopoverArrowDirectionDown animated:YES];
}
现在，我希望弹出窗口漂浮在 inputView 上，并且指针将触摸我放置在视图中的按钮。但事实并非如此。在“X”原点中，弹出点是正确的。但是，当 UIView 作为输入视图时，它不允许弹出框在 inputView 上向下移动到 UIButton。我是否忽略了什么？

I am trying to set up a popover to point to a UIButton in a view that is used as a "inputView" to a UITextView. I can get everything to work and the correct data is going into the UIPopoverController. But it is exhibiting a behavior that is not what I expected. So here is what I have. The following method is written in a UIView subclass that is the inputView of the UITextView and is also the view in which the button resides.
- (IBAction)buttonTouchDown:(id)sender {
UIButton *button = (UIButton *)sender;
MyPopoverContentController *controller = [[MyPopoverContentController alloc] initWithNibName:@"MyNib" bundle:nil];
[controller setContentSizeForViewInPopover:CGSize(320.0, 304.0)];
self.popupController = [[UIPopupController all] initWithContentViewController:controller];
[self.popupController presentPopoverFromRect:[button frame] inView:self permittedArrowDirectoions:UIPopoverArrowDirectionDown animated:YES];
}
Now, I would expect the popover to float over the inputView and the pointer would touch the button I've placed into the view. But it does not. In the 'X' origin the popover point is correct. But it appears the UIView when acting as a input view it won't allow the popover to move down over the inputView to the UIButton. Am I overlooking something?
Thanks for any help,
Rob
