In the Clock application under alarms, this behavior can be verified. After creating a new alarm, try opening the alarm, editing the time of the alarm. WHILE THE DIAL IS STILL MOVING, hit the save button. The value you had scrolled to will be replaced by the value that the scrollers were last stopped at. I am using a UIDatePicker in a UIActionSheet and feel that if the wheel is still BARELY scrolling, someone will get eager and click the done button before the scroller finishes.
I realize this is probably very picky, but does anyone know of any possible way to fix this aside from writing a custom class?
