Q: Maximum size of UIImage tiles for iPhone 4 I have an iPhone app containing a large static image, which is sliced into 1024x1024 tiles and put in an UIScrollView. I'm not clear whether I can use larger tiles on the iPhone 4.
If I want to support a double-res image for iPhone 4, should I:


*

*Create 2048x2048 tiles with a @2x suffix
or

*Create 4 times as many 1024x1024 tiles and write logic to load in these tiles on the iPhone 4 


A: For iPhone 4 create 2048x2048 tiles with a @2x suffix. Then you have not change your code. Just add these images.
