Using CGContext to display a sprite sheet iPhone

Question

So I have a spritesheet in png format, and have already worked out the coordinates for what I want to display. I\'m trying to create a method that will return a UIImage when

Answer 1

I think the call you want to use is CGImageCreateWithImageInRect

newImage = [UIImage imageWithCGImage:CGImageCreateWithImageInRect( [spriteSheet CGImage] , imageRect )];

Answer 2

you need to think of your co-ordinates backwards. The CGSize is fixed. Translate your xPos,yPos so that your sprite appears under the window.
