NSLog(@"rotate");

if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)){
    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; 

    // Rotate 90 degrees to hide it off screen
    CGAffineTransform rotationTransform = CGAffineTransformIdentity;
    rotationTransform = CGAffineTransformRotate(rotationTransform,DegreesToRadians(0));
    delegate.imgV.transform = rotationTransform;

}
else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation)){
    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; 

    // Rotate 90 degrees to hide it off screen
    CGAffineTransform rotationTransform = CGAffineTransformIdentity;
    rotationTransform = CGAffineTransformRotate(rotationTransform,DegreesToRadians(90));
    delegate.imgV.transform = rotationTransform;

}

Enjoy :-)

DegreesToRadians is define value. like-- #define DegreesToRadians(x) (M_PI * (x) / 180.0) – Jayendra Aug 21 '12 at 05:50
I have added #define also but it's not working see screenshot – Rahul Vyas Aug 21 '12 at 08:25
once try to change your image view frame size when device is orientated. – Jayendra Aug 21 '12 at 09:25
I think window orientation is always portrait. you should check the uidevice orientation and set the imageview transformation. – Mitesh Khatri Aug 21 '12 at 13:26
