How to test the state of a UISegmentedControl

We can use the selectedSegmentIndex property for this.
Our segmented control thingy starts at 0 for the first value:

    if (segmentSwitch.selectedSegmentIndex == 0 ) {
        segmentLabel.text = @"You've selected YES";
    } else {
        segmentLabel.text = @"You've selected NO";

If you want to trigger an action when someone makes a selection you can query the UIControlEventValueChanged event or just connect an IBAction.
