touch buttons function OnGUI issue

Question

I am trying to make a touch button function for android.

You would call touch.Button and have options similar to the GUI.Button, but there is an issue

I want to be able to use labels and images for this button, because of this I am calling the function in OnGUI.

This on the other hand gets triggered much faster than the Update function, so it tends to return true multiple times for a button triggered when touched down using touch.phase = TouchPhase.Began

I could call it out of the Update function, but then I would no longer be able to use Labels (I could still use Graphics.DrawTexture for images)

I tried many things but couldn't find a good solution.

Thanks in advance

mouse or touch events will be checked every frame.

OnGUI is called multiple times every frame.

So use somethink like this:

 long lastCheckFrameCount = 0;
 private bool onGuiCheckTouch()
 {
     if(Time.frameCount == lastCheckFrameCount)
     {
         return false;
     }
     else
     {
         lastCheckFrameCount = Time.frameCount;
         return Input.touchCount > 0;
     }
 }
