uiImageButton has been working for me for a while now.
Do you have a pic of your example sawan? Your total image size should be 48×24 stiched vertically. Your frame settings in controller for that image should then be set to 24×24.
What I wonder about is if your image shows the background during the off state, how do you see the button to enable it?

I’d be glad to assist you in getting this to work. Show me what your trying to do.
