 UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"Add Title" message:@"Add Message" preferredStyle:UIAlertControllerStyleAlert];
     UIAlertAction * actionOK = [UIAlertAction actionWithTitle:@"Button Title" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
                        //Here Add Your Action
                    }];
     UIAlertAction * actionCANCEL = [UIAlertAction actionWithTitle:@"Second Button Title" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
                        //Add Another Action
                    }];


               [alert addAction:actionOK];

Use this code

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction * continueButton = [UIAlertAction actionWithTitle:@"Continue" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action){
      [self performSegueWithIdentifier:@"createlogin" sender:self];
  }];
 UIAlertAction * cancelButton = [UIAlertAction actionWithTitle:@"cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action){

  }];
[alert addAction:continueButton];
[alert addAction:cancelButton];
[self presentViewController:alert animated:YES completion:nil];

try this:

UIAlertController *controller = [UIAlertController alertControllerWithTitle:@"Your message title"
                                                                                message:@"Enter your message here."
                                                                         preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action)
 {
     NSLog(@"Ok Action");
 }];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"Skip" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action)
 {
     NSLog(@"Cancel Action");
}];

[controller addAction:okAction];
[controller addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:nil];
