How to fade in GUI text.

Question

So I have a few GUI.Label, and a few GUI.Styles to go with them. Since there are a few different ones to each there own settings. So how can I fade these labels in? I know the most simple way is to adjust the alpha. I did this before on fading a character renderer. I tried this with the text and the alpha isn't accessing anything. Saying used as a property but can't because its a type. Can someone write a simple line of code to show me how to do this correctly please?

Sorry i have updated my unity to the new UI 4.6 so i don't remember exactly how to do it but you should first get the Gui text component then acces the color alpha.

 var GuiLabel : GUIText;
 
 GuiLabel.color.a = yourValue;
 
 //OR
 
 SomeGameObject.GetComponent(GUIText).color.a = yourValue;

If you are getting an error post it and post your code.

 public float alpha = 1.0f;
 public float fadeSpeed = 2.0f;
 void OnGUI()
 {
 
         if(GUI.Button(new Rect(Screen.width/2, Screen.Height/2, 200, 50))
          {
            StartCoroutine(Fade());
          }
         GUI.color = new Color(255, 255, 255, alpha);// adjust alpha value
         GUI.Label(new Rect(0, 0, 200, 50), "Label");
         //All elements to fade
         GUI.color = new Color(255, 255, 255, 1); // sets it back to 1 for another elements
 }
 IEnumerator Fade()
 {
     alpha = 0;
     while (alpha < 1f)
     {
         alpha += Time.deltaTime*fadeSpeed;
         yield return null;
     }
 }
