Rotate UIImage?

Can you rotate a UIImage without using a transform on UIImageView. I'm using a UIImage as a custom pin on a map and would like to rotate it if possible?

yess you can rotate and UIImage in predefined ImageOrientations:

UIImage *rotatedImage = [UIImage imageWithCGImage:imageObject.CGImage scale:imageObject.scale orientation:UIImageOrientationUp];

here orientation is predefined enum variable:

UIImageOrientationUp,
UIImageOrientationUpMirrored
UIImageOrientationDown
UIImageOrientationDownMirrored
UIImageOrientationLeft
UIImageOrientationRight    etc

it rotates UIImage.

No. The only thing you might be able to do is to set the UIImageOrientation to coheres the OS into rotating it for you on the basis of that - though that will only give you the four (main) 90-degree rotations.
