Detecting a change in UISwitch

Question

This sounds trivial but I'm noticing some weirdness. I've wired up a handler for the Value Changed event of a UISwitch. What I would expect is that each time the handler is called the value of the switch would change. But that's actually not always the case. If you press the switch rapidly on/off the handler can get called consecutively with the SAME state for the switch (in my specific application this is an issue). So I'm wondering if anyone else has noticed this behavior and has figured out a good solution.

   -(void) createSwitch     {         self.searchExistSearchNewSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(0,0,0,0)];         [self.searchExistSearchNewSwitch addTarget:self action:@selector(switchValueChanged:) forControlEvents:UIControlEventValueChanged];         [self.view addSubview:self.searchExistSearchNewSwitch];     }     - (void)switchValueChanged:(UISwitch *)theSwitch     {         BOOL flag = theSwitch.isOn;     }
