Phone: Rotate a UIImageView

Here's a simple little snippet that's useful if you want to rotate a UIImageView continuously for something like a clock hand graphic:

#define DEGREES_TO_RADIANS(__ANGLE__) ((__ANGLE__) / 180.0 * M_PI)

CGAffineTransform cgCTM = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(45));
myImage.transform = cgCTM;
