问题描述

我将模态视图控制器呈现为表单，并在单击取消按钮(它是条形按钮项)时将其关闭.当我在该视图之外点击时，我需要关闭它.请帮我参考.注意:我的模态视图控制器带有一个导航控制器.

I am presenting a modal view controller as a form sheet and dismissing it when the cancel button, which is a bar button item, is clicked. I need to dismiss it when I tap on outside of that view. Please help me with a reference. Note: my modal view controller is presented with a navigation controller.

@cli_hlt，@Bill Brasky 感谢您的回答.当点击发生在作为表单的模式视图之外时，我需要关闭它.我在下面粘贴我的代码.

@cli_hlt, @Bill Brasky thanks for your answer. I need to dismiss it when tap occurs outside of the modal view which is a form sheet. I am pasting my code below.

-(void)gridView:(AQGridView *)gridView didSelectItemAtIndex:(NSUInteger)index  
{        
    if(adminMode) 
    {
        CHEditEmployeeViewController *editVC = [[CHEditEmployeeViewController alloc] initWithNibName:@"CHEditEmployeeViewController" bundle:nil];
        editVC.delegate = self;
        editVC.pickedEmployee = employee;
        editVC.edit = TRUE;
        editVC.delegate = self;
        UINavigationController *navigationController = [[UINavigationController alloc]initWithRootViewController:editVC];
        navigationController.modalPresentationStyle = UIModalPresentationFormSheet;
        [self presentModalViewController:navigationController animated:YES];

        return;
    }   //the above code is from the view controller which presents the modal     view. Please look at the below code too which is from my modal view controller. Please guide me in a proper way.   -(void)tapGestureRecognizer {

    UITapGestureRecognizer *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 addGestureRecognizer:recognizer];

}

- (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:sender];
        }

    }
}
