[menu setSelectedSegmentIndex:-1];

menu being the UBOutlet for uisegmentedcontrol but this gives me exception. anyone have some idea? thanks peter

Answer 1

I would assume that you've called [myArray length] instead of the proper [myArray count] somewhere in your code. NSArray uses the count method, not length for the number of items it contains.

Answer 2

The right way to do this is:

[menu setSelectedSegmentIndex:UISegmentedControlNoSegment];

Answer 3

I guess you try to create a momentary selection in segmented control. In interface builder set the segmentedcontrol to momentary. Or in code you can do:

menu.momentary = YES;

Answer 4

Setting the segmentedControl to .momentary = YES changes the way the user can interact with the segmentedControl. If you want to have nothing selected initially when the page loads but have segmentedControl behave the same after a selection is made by the user then you will want something more like this:

Swift 4 solution:

 @IBOutlet weak var segmentedControl: UISegmentedControl!

 self.segmentedControl.selectedSegmentIndex = UISegmentedControlNoSegment

Answer 5

You can now do this in xcode 6 in the interface builder:

Deselect the 'Selected' option under segmented control behaviour in attributes inspector.

Answer 6

swift 4

@IBOutlet weak var segmentControl: UISegmentedControl! {
    didSet {
        segmentControl.selectedSegmentIndex = UISegmentedControl.noSegment
    }
}

Answer 7

The Swift solution: @IBOutlet weak var mySegmentedControl: UISegmentedControl! and mySegmentedControl.selectedSegmentIndex = -1.
