Solution

  • Try similar code

    -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.2];
    CGAffineTransform rr=CGAffineTransformMakeRotation(5);
    yourView.transform=CGAffineTransformConcat(yourView.transform, rr);
    [UIView commitAnimations];
}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    [self touchesBegan:touches withEvent:event];
}
