Properly Present a UIAlertController from MSMessagesAppViewController

Question

I'm trying to figure out how to display a UIAlertController with a style of UIAlertControllerStyleActionSheet within my iMessage app extension.

The problem is, the action sheet appears below the native iMessage text field when presented when calling:

[self.view.window.rootViewController presentViewController:actionSheetController animated:YES completion:NULL];

How would I go about fixing this?

Code:

UIAlertController *actionSheetController = [UIAlertController alertControllerWithTitle:NSLocalizedString(@"Clear", nil) message:nil preferredStyle:UIAlertControllerStyleActionSheet];

UIAlertAction *clear = [UIAlertAction actionWithTitle:NSLocalizedString(@"Clear", nil) style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action)
{
    [self clear];
}];

UIAlertAction *cancel = [UIAlertAction actionWithTitle:NSLocalizedString(@"Cancel", nil) style:UIAlertActionStyleCancel handler:^(UIAlertAction *action)
{}];

[actionSheetController addAction:clear];
[actionSheetController addAction:cancel];

[self.view.window.rootViewController presentViewController:actionSheetController animated:YES completion:NULL];

Answer 1

Another workaround:

actionSheetController.view.transform = CGAffineTransform(translationX: 0, y: -40)    
[self.view.window.rootViewController presentViewController:actionSheetController animated:YES completion:NULL];

Here is a workaround. Maybe add a little animation to make it smooth.

[self.view.window.rootViewController presentViewController:actionSheetController animated:YES completion:^{
    actionSheetController.view.frame = CGRectOffset(actionSheetController.view.frame, 0, -40);
}];
