How to Dismiss Uialertcontroller When Tap Outside the Uialertcontroller

How to dismiss UIAlertController when tap outside the UIAlertController?

Add a separate cancel action with style UIAlertActionStyleCancel. So that when user taps outside, you would get the callback.

Obj-c

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Alert Title" message:@"A Message" preferredStyle:UIAlertControllerStyleActionSheet];
[alertController addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
 // Called when user taps outside
}]];

Swift 5.0

let alertController = UIAlertController(title: "Alert Title", message: "A Message", preferredStyle: .actionSheet)             
alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { 
    action in
         // Called when user taps outside
}))

Don't dismiss uialertcontroller sheet with tap gesture outside dialog area in iOS

for UIAlertController Type as alert

you can download the sample project

add the gesture recognizer to alertController superview for handle the userinteraction

self.present(alertController, animated: true, completion: {() -> Void in
 alertController.view.superview?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil)
})

on that action do nothing

update

let alertController = UIAlertController(title: "Do something", message: "With this", preferredStyle: .alert)
    alertController.addAction(UIAlertAction(title: "Done", style: .default) { action in
        // perhaps use action.title here
    })

    self.present(alertController, animated: true, completion: {() -> Void in


        alertController.view.superview?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))
    })

for UIAlertController Type as actionSheet

you can download the sample project

you can do this two ways

option 1

 alert.view.superview.subviews[0] isUserInteractionEnabled = false

option 2

   alert.view.superview?.subviews[0].addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))

for e.g

   self.present(sheet, animated: true, completion: {() -> Void in
    //    sheet.view.superview?.subviews[0].isUserInteractionEnabled = false;
      sheet.view.superview?.subviews[0].addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))

    })

full code

  let sheet = UIAlertController(title: "karthik", message: "check with", preferredStyle: .actionSheet)

    sheet.addAction(UIAlertAction(title: "Create Ticket", style: .default) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Start VM", style: .default) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Restart VM", style: .default) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Stop VM", style: .destructive) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Cancel", style: .cancel) { (action: UIAlertAction) in

    })



    self.present(sheet, animated: true, completion: {() -> Void in
    //    sheet.view.superview?.subviews[0].isUserInteractionEnabled = false;
      sheet.view.superview?.subviews[0].addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))

    })

Dismiss UIAlertController after few seconds?

May below code will do the work:

UIAlertController *alert=   [UIAlertController
                                alertControllerWithTitle:@"Please wait, checking your PAID INVOICE, to allow the service."
                                message:"...waiting..."
                                preferredStyle:UIAlertControllerStyleAlert];

[self.window.rootViewController presentViewController:alert animated:YES 
  completion:nil]; 


dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        [alert dismissViewControllerAnimated:YES completion:^{

            //Dismissed
        }];

});
