Method invocation in UIViewController from UIButton in preview

Question

Continuing to learn Objective-C and building the structure correctly.

I have an iOS application with a UIViewController that has a specific method called "doSomething". In my opinion, the controller has a view and in this view there are several UIButton that I create programmatically (see the example with one button below).

Now, when I click the button, I want to call my "doSomething" method. The way I am doing this now is as follows:

[myButton addTarget:nil 
             action:@selector(doSomething:)
     forControlEvents:UIControlEventTouchUpInside];

Since my goal is zero, it goes up the defendant chain until it finds the "doSomething" method. It works, but in fact it does not feel good.
