Question

所以我通常按照这种方式在其视图外点击时忽略ModalViewController

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    if(UIUserInterfaceIdiomPad == UI_USER_INTERFACE_IDIOM())
    {
        if(![self.view.window.gestureRecognizers containsObject:recognizer])
        {
            recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)];

            [recognizer setNumberOfTapsRequired:1];
            recognizer.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view
            [self.view.window addGestureRecognizer:recognizer];
            [recognizer release];
        }
    }
}

- (void)handleTapBehind:(UITapGestureRecognizer *)sender
{
    if (sender.state == UIGestureRecognizerStateEnded)
    {
        CGPoint location = [sender locationInView:nil]; //Passing nil gives us coordinates in the window

        //Then we convert the tap's location into the local view's coordinate system, and test to see if it's in or outside. If outside, dismiss the view.

        if (![self.view pointInside:[self.view convertPoint:location fromView:self.view.window] withEvent:nil]) 
        {
            [self dismissModalViewControllerAnimated:YES];
            [self.view.window removeGestureRecognizer:recognizer];
        }
    }
}

它与常规 ModalViewController工作良好..但现在我有一个modelViewController，它是一个NavigationViewController，以“x”viewController作为根目录..当我使用这种方式并点击navigationBar时控制器被解雇，或者当我从x控制器导航到“y”控制器并想要回来时，当我单击后退按钮时，ModalView被解除！这对我来说是错误的行为..我只是希望控制器被解雇，以防水龙头完全在控制器外（查看区域+导航栏区域）..任何人都可以提供帮助吗？

更新以下代码：

- (void)handleTapBehind:(UITapGestureRecognizer *)sender
{
    if (sender.state == UIGestureRecognizerStateEnded)
    {
        CGPoint flocation = [sender locationInView:nil]; //Passing nil gives us coordinates in the window

        //Then we convert the tap's location into the local view's coordinate system, and test to see if it's in or outside. If outside, dismiss the view.

        CGPoint tap = [self.view convertPoint:flocation fromView:self.view.window];
        CGPoint tapBar = [self.navigationController.navigationBar convertPoint:flocation fromView:self.view.window];
        if (![self.view pointInside:tap withEvent:nil] && ![self.navigationController.navigationBar pointInside:tapBar withEvent:nil])
        {
            // Remove the recognizer first so it's view.window is valid.
            [self.view.window removeGestureRecognizer:sender];
            [self dismissModalViewControllerAnimated:YES];
        }
    }
}

点击UIBarButtonItem时从窗口中删除UITapGestureRecognizer

-(void)viewWillDisappear:(BOOL)animated {
    [self.view.window removeGestureRecognizer:self.tapOutsideGestureRecognizer];
}

在iPad中使用NavigationController关闭ModalViewController当在视图外部点击时
