Hi, with the default values the rotation take place but changing the value not. I bind a button to a slider action:

-(IBAction)rotateXAction:(id)sender
{
    NSLog(@"%@ \n",sender);
    BOOL yn = YES;
    _rotationX =  [_sliderX intValue];
    if(yn) printf("rotationX %d \n",_rotationX); // value o.k
    [self setNeedsDisplay:YES];
}

The drawRect: will not be called. What is wrong with my code, please tell me. Uwe

Are you sending setNeedsDisplay to the right view?
