Adding Zoom Capability to App

[bgd223]

I've followed tutorials in which you can have an image view within a scroll view, and then zoom in on the image and pan. However, I am interested in having the capability to zoom in on the entire view (specifically through double tapping), and enlarge everything (labels, buttons, images, etc). I have spent days looking for help in vain, so I have come here. Any and all help is greatly appreciated.
