Question: I am a departed Microsoft Visual Studio programmer and have to build some iPhone apps now. What are the supported image types in iPhone 4 projects? Can I use Microsoft bitmaps and video formats? Answer: Welcome to the club. In iOS, all drawing, regardless of OpenGL, Quartz, UIKit, or Core Animation…, occurs within an UIView object. UIView-s define the portion of the screen in which drawing occurs. We usually do not need custom drawing code. UIKit supports the UIImage class, which implements an immutable class for displaying images. The link to this widely used class reference is further down.
