Rotate the view only in ios

Question

My application is only supported on Portrait mode. I have requirement that need to rotate the particular UIView only according to the device orientation.

Can you please help me?

After the long try I found the answer using CGAffineTransform ..

- (void)deviceOrientationDidChange:(NSNotification *)notification {
    //Obtain current device orientation
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

    CGFloat angle;
    switch (orientation) {
        case UIDeviceOrientationPortraitUpsideDown:
            angle = M_PI;
            break;
        case UIDeviceOrientationLandscapeRight:
            angle = - M_PI_2;
            break;
        case UIDeviceOrientationLandscapeLeft:
            angle = M_PI_2;
            break;
        case UIDeviceOrientationPortrait:
        default:
            angle = 0.f;
            break;
    }
    animationView.transform= CGAffineTransformMakeRotation(angle);
    animationView.frame = self.view.frame;
}
