How do I determine when scroll UIDatePicker completed?

Question

I use UIDatePicker and I want to know when scrolling in UIDatePicker is over. Thank you.

The UIDatePicker does not expose the scrolling events, but does send an event when the selected value has changed. You can use UIControlEventValueChanged to track this.

[myDatePicker addTarget:self action:@selector(dateSelected:) forControlEvents:UIControlEventValueChanged];
