How to rotate UIImage

I'm developing an iOS app for iPad. Is there any way to rotate a UIImage 90º and then add it to a UIImageView? I've tried a lot of different codes but none worked...

Thanks!

Solution

  • You may rotate UIImageView itself with:

    UIImageView *iv = [[UIImageView alloc] initWithImage:image];
iv.transform = CGAffineTransformMakeRotation(M_PI_2);

    Or if you really want to change image, you may use code from this answer, it works.
