How to dismiss UIAlertController
when tap outside the UIAlertController
?
I can add a UIAlertAction
of style UIAlertActionStyleCancel
to dismiss the UIAlertController
.
But I want to add the function that when user tap outside the UIAlertController
the UIAlertController
will dismiss. How to do that? Thank you.
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
}))
