使用-dismissPopoverAnimated：拒绝UIPopoverController不会调用delegate？ [英] Dismissing UIPopoverController with -dismissPopoverAnimated: won't call delegate?

问题描述

我有我的UIPopoverController与self作为委托：
当我点击外面的popover控制器时接收调用，但是当我点击里面我想也关闭，所以我使用-dismissPopoverAnimated：但委托没有被调用在这种情况下。
这是正常吗？这是一个错误还是我做错了？

I have my UIPopoverController with self as a delegate: I receive calls when I tap outside the popover controller, but when I tap inside I want to dismiss too, so I use -dismissPopoverAnimated: but delegate is not called in this case. Is this normal? Is this a bug or I am doing something wrong?

newDocPopoverController = [[UIPopoverController alloc] initWithContentViewController:vc];
[newDocPopoverController setPopoverContentSize:CGSizeMake(240, 44*4)];
[newDocPopoverController presentPopoverFromBarButtonItem:sender 
                permittedArrowDirections:UIPopoverArrowDirectionAny
                                                        animated:YES];
[newDocPopoverController setDelegate:self];

更新：

问题的起源（无论是错误还是这是预期的行为）调用委托由自己解决问题:)

Oh, regardless the origin of the problem (Whether is a bug or this is the intended behavior) calling the delegate by myself solves the problem :)

当contentViewController的视图被触摸，我会调用父UIPopoverController的委托调用。

When the contentViewController's view is touched I will call parent UIPopoverController's delegate a call.

if ([parentPopoverController.delegate popoverControllerShouldDismissPopover:parentPopoverController]){
    [parentPopoverController dismissPopoverAnimated:YES];
    [parentPopoverController.delegate popoverControllerDidDismissPopover:parentPopoverController];
}r];

推荐答案

这是正常的，预期的行为。

That's normal, expected behavior.

引用 Apple docs popoverControllerDidDismissPopover：：

popover控制器不会调用此方法来响应对 dismissPopoverAnimated：方法的编程调用。如果您以编程方式关闭popover，则应在调用 dismissPopoverAnimated：方法后立即执行任何清除操作。

The popover controller does not call this method in response to programmatic calls to the dismissPopoverAnimated: method. If you dismiss the popover programmatically, you should perform any cleanup actions immediately after calling the dismissPopoverAnimated: method.
