How can I set the default state of a UISegmentedControl?

Question

Is there a way to set the starting selected segment in a UISegmentedControl in Interface Builder, or do I have to do it in the code? If it's in the code, is viewDidLoad the best place to set it?

Answer 1

From code, you can do:

self.segmentedControl.selectedSegmentIndex = someDefaultIndex

Whether you should set it in viewDidLoad: or not depends entirely on the structure of your application. For example, if your app is starting up and loading the view for the first time and needs to set the control to whatever value it had during the previous run of the app, then it definitely makes sense to do it there.

Answer 2

In Interface Builder when you select UISegmentedControl object on your UI, then in attributes pane, in segment control there's segment drop down menu, select segment that you want selected (0,1 and so on) and tick the 'selected' option below it.

Answer 3

Select default value for your UISegmentedControl via storyBoard

1. Open ur storyboard and select the UISegmentedControl

2. Select atributes inspector of your UISegmentedControl (in the right corner)

3. Search the 'segment' atribute and open de dropdown.

4. Select the item you want to be selected by default.

5. Mark the selected checkbox to set selected by default.
