Instead of using touchesEnded: (which shouldn't be used for this purpose anyway), attach an action to the UISlider's UIControlEventValueChanged event and set the continuous property of the UISlider to NO, so the event will fire when the user finishes selecting a value.

mySlider.continuous = NO;
[mySlider addTarget:self
          action:@selector(myMethodThatFadesObjects) 
          forControlEvents:UIControlEventValueChanged];
