Speaking of Sleeps to Christmas 2, here’s a quick tip for quickly putting together an iPad version of an app. I don’t think this is an original idea but I’m not sure where I saw it.
The key thing to realise is that if you already have retina display artwork for the iPhone 4 in portrait mode then that’s usually 640×920 pixels. An iPad’s display in portrait is 768×1004. Only a 128×84 pixel difference.
See where I’m going with this?
Yes, you ask your friendly illustrator to make you a frame for around the artwork!
And then all you need to do is add a toolbar where each button shows the view controllers from your iPhone version in a popover, telling it to hide the navigation bar on the view controller if we’re on an iPad and you’re done.
Creating a (admittedly simple) iPad version of Sleeps to Christmas 2 took about a couple of hours of artwork and less than one hour of coding. I’ll likely work on a better port in the future but for now this was good enough that I was happy to ship it as a 1.0.
