Question

I walked over other same question but it didn’t help.
I have an image that should rotate every doubleTap by 90 degrees

This is the rotation function

-(void) rotateImageWithAngle:(float)angle1
{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.2];
    [UIView setAnimationBeginsFromCurrentState:YES];

    CGAffineTransform transform;
    transform = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(angle1));
    self.transform = transform;

    [UIView commitAnimations];   
}

angel1 is always 90.
The problem is that it rotates only once, every additional doubleTap goes to the function but does nothing.

Thanks

You’re applying the same transform every time. You should change the angle by 90 degrees with each double tap.
