Dismiss UIAlertController after few seconds?

I need to show a box without submit button but let it disappear after 3 second. Is it possible to attach any timeout?

  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];

You can also try this: For Objective-C

    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"message" preferredStyle:UIAlertControllerStyleAlert];
    [self presentViewController:alertController animated:YES completion:^{
        [self performSelector:@selector(dismissAlertController:) withObject:alertController afterDelay:3.0];
    }];

    - (void)dismissAlertController:(UIAlertController *)alertController {
        [alertController dismissViewControllerAnimated:YES completion:nil];
    }

For Swift 3

    let alertController = UIAlertController(title: "Title", message: "message", preferredStyle: .alert)
    present(alertController, animated: true) { 
        self.perform(#selector(ViewController.dismissAlertController(alertController:)), with: alertController, afterDelay: 3.0)
    }

    internal func dismissAlertController(alertController: UIAlertController) {
        alertController.dismiss(animated: true, completion: nil)
    }

Following on from @RonakChaniyara's answer, this adds a test that the alert is still presented (if using with an alert that has a button to dismiss, for example).

[presentViewController:alert animated:YES completion: {

    // Dispatch 3 seconds after alert presented
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        // Check that alert is still presented
        if self.presentedViewController == alert {
            // Dismiss if it is
            [self.dismissViewControllerAnimated:YES completion:^{    
                //Dismissed
            }];    
        }
    });
}];

and in Swift…

let alert = UIAlertController(title: "Please Wait", message: "…waiting…", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .cancel, handler: nil))

present(alert, animated: true) {
    DispatchQueue.main.asyncAfter(deadline: .now() + 3) { [weak self] in
        guard self?.presentedViewController == alert else { return }

        self?.dismiss(animated: true, completion: nil)
    }
}

add performSelector with your alertController and create your UIAlertController object as gobally

 [self performSelector:@selector(hideAlertView) withObject:nil afterDelay:3.0];

-(void)hideAlertView{
 [alert dismissViewControllerAnimated:YES completion:nil];  // or use [self dismissViewControllerAnimated:alert completion:nil];
}

You can use this code to dismiss your UIAlertController. You need to declare UIAlertController globally.

[self performSelector:@selector(removeAlert) withObject:nil afterDelay:3];

Your selector method

-(void)removeAlert{
    [self dismissViewControllerAnimated:alert completion:nil];
}

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
        }];

});

The best way would be to subclass UIAlertController, to your own class, and in the viewDidAppear, add a NSTimer to dismiss automatically.

Don't forget to invalidate the timer and to release it in the viewDidDisappear method

You may try it like this:

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)),     dispatch_get_main_queue(), ^{
    [alert dismissViewControllerAnimated:YES completion:nil];
});
