UISegmentedControl value changed programmatically

How can I hook up my UISegmentedControl's value changed method programmatically. I 开发者_如何学Goknow it's possible using IB but I was wondering how to do it with code. Thanks.

Attach a target-action for the control event UIControlEventValueChanged.

Example

[segmentedControl addTarget:self action:@selector(valueChanged:) forControlEvents: UIControlEventValueChanged];

You can use the addTarget:action:forControlEvents method.

UISegmentControl *mySegmentedControl = [UISegmentControl ...];
[mySegmentedControl addTarget:self action:@selector(segmentValueChanged:) forControlEvents:UIControlEventValueChanged];
