I think, you have been perform task with them. But I think it's useful for someone.

Below code is working perfectly with my requirements. Please do changes according to your requirements.

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
                                                                         message:nil
                                                                  preferredStyle:UIAlertControllerStyleActionSheet];

UIAlertAction *setCoverPhoto = [UIAlertAction
                                actionWithTitle:@"First Button"
                                style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction *action){

                                    NSLog(@"First Button");

                                }];
[alertController addAction:setCoverPhoto];


UIAlertAction *deleteImageAct = [UIAlertAction
                                 actionWithTitle:@"Second Button"
                                 style:UIAlertActionStyleDefault
                                 handler:^(UIAlertAction *action) {

                                     NSLog(@"Second Button");

                                 }];
[alertController addAction:deleteImageAct];

UIAlertAction *setImageASNotif = [UIAlertAction
                                  actionWithTitle:@"Third Button"
                                  style:UIAlertActionStyleDefault
                                  handler:^(UIAlertAction *action) {

                                      NSLog(@"Third Button");

                                  }];
[alertController addAction:setImageASNotif];


alertController.view.tintColor = [UIColor whiteColor];

UIView *subView = alertController.view.subviews.firstObject;
UIView *alertContentView = subView.subviews.firstObject;
[alertContentView setBackgroundColor:[UIColor darkGrayColor]];

alertContentView.layer.cornerRadius = 5;

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

Pretty darn good tutorial over at Matt Thompson's site:
