Fire and Forget Class in ARC

I needed to create a custom one UIAlertViewfor my application, and I came across this article describing how to do this. I’ve made a few changes since then, but it’s all the more important that this class does not work as a “Fire and Forget” warning, as it does UIAlertView, because ARC does not allow naming retain.

So basically, I want to be able to use my custom alert view in the same way as the normal alert view, so I can create and display it like this:

CustomAlertView *alert = [[CustomAlertView alloc] init];//Init presumably does the view setup
[alert show];

So my question is: how can I make this object not freed up as soon as it leaves the scope when working in an ARC project without creating a link strongto it in the calling class?

EDIT

I believe it is important to note that in order to get the full freedom of customization that I wanted, I had to make it a new ViewController class, it is NOT a subclassUIAlertView

Sorry, I didn’t look at my link too closely, initially I had the wrong textbook. THIS is the right study guide. I based my opinion on
