in fact the title contains my question. I have a UISegmentedControl, and need to deselect currently selected tab. I tried:
[menu setSelectedSegmentIndex:-1];
The right way to do this is:
[menu setSelectedSegmentIndex:UISegmentedControlNoSegment];
You can now do this in xcode 6 in the interface builder:
Deselect the 'Selected' option under segmented control behaviour in attributes inspector.
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
Swift 5.1:
self.segmentedControl.selectedSegmentIndex = UISegmentedControl.noSegment
The Swift solution: @IBOutlet weak var mySegmentedControl: UISegmentedControl!
and mySegmentedControl.selectedSegmentIndex = -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.
swift 4
@IBOutlet weak var segmentControl: UISegmentedControl! {
didSet {
segmentControl.selectedSegmentIndex = UISegmentedControl.noSegment
}
}
