Swift - Calling @IBAction from another method without parameter
<p>This is my first question and I would like to ask if anyone knows how to call a @IBAction button from another function
Here is an example of my code </p>

<pre><code>@IBAction func button1(sender: UIButton) {
    super.viewDidLoad()   
}

@IBAction func customPage(sender: AnyObject) {
    super.viewDidLoad() 
}
</code></pre>

<p>and I would like to change the text of button 1 from the customPage Function</p>
