Action Sheets with UIAlertController

suggest change

With UIAlertController, action sheets like the deprecated UIActionSheet are created with the same API as you use for AlertViews.

Simple Action Sheet with two buttons

Swift

let alertController = UIAlertController(title: "Demo", message: "A demo with two buttons", preferredStyle: UIAlertControllerStyle.actionSheet)

Objective-C

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Demo" message:@"A demo with two buttons" preferredStyle:UIAlertControllerStyleActionSheet];

Create the buttons “Cancel” and “Okay”

Swift

let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (result : UIAlertAction) -> Void in
    //action when pressed button
}
let okAction = UIAlertAction(title: "Okay", style: .default) { (result : UIAlertAction) -> Void in
    //action when pressed button
}

Objective-C

UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {
        //action when pressed button
    }];

UIAlertAction * okAction = [UIAlertAction actionWithTitle:@"Okay" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
        //action when pressed button
    }];

And add them to the action sheet:

Swift

alertController.addAction(cancelAction)
alertController.addAction(okAction)

Objective-C

[alertController addAction:cancelAction];
[alertController addAction:okAction];

Now present the UIAlertController:

Swift

self.present(alertController, animated: true, completion: nil)

Objective-C

[self presentViewController:alertController animated: YES completion: nil];

This should be the result:

Action Sheet with destructive button

Using the UIAlertActionStyle .destructive for an UIAlertAction will create a button with red tint color.

For this example, the okAction from above was replaced by this UIAlertAction:

Swift

let destructiveAction = UIAlertAction(title: "Delete", style: .destructive) { (result : UIAlertAction) -> Void in
    //action when pressed button
}

Objective-C

UIAlertAction * destructiveAction = [UIAlertAction actionWithTitle:@"Delete" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * action) {
            //action when pressed button
        }];
