How can I enable multiple segments of a UISegmentedControl to be selected?

Question

Lets say my UISegmentedControl has 8 numbered segments. I would like for the user to be able to turn on 2, 3, or more of them at once. Toggling them. Essentially like a bits

Answer 1

I recommend you try https://github.com/tayhalla/THSegmentedControl
it is an actual subclass of UISegmentedControl so it fits nicely with Interface builder and everything.

Answer 2

This isn't possible using UIKit. I would recommend creating a custom control, or an array of UISwitch controls, representing each of the options in your UISegmentedControl.

Answer 3

There appears to be a way to do this in XCode now. In the Attributes Inspector, there is a section with Segment, Title, Image, Behavior. The behavior options are "Enabled" and "Selected". You can selecte "Selected" for multiple segments.

Answer 4

Answer for those who will come here from Google: it's now possible to change the behaviour of a UISegmentedControl. Go to Inspector -> Mode -> Select Any instead of Select One. To find out which segments are selected I suggest to create a function like this one:

extension UISegmentedControl {
    func getBarState() -> [Bool] {
        var states: [Bool] = []
        for i in 0..<segmentCount {
            states.append(isEnabledForSegment(forSegment: i))
        }
        return states
    }
}

As Google brought me here while searching for the OSX version I'll also post a working solution for NSSegmentedControl:

extension NSSegmentedControl {
    func getBarState() -> [Bool] {
        var states: [Bool] = []
        for i in 0..<segmentCount {
            states.append(isSelected(forSegment: i))
        }
        return states
    }
}

Answer 5

I think the simplest way is to create your own segmentedcontrol with UIButton.

Answer 6

This is the best custom control I've found that allows multiple segments to be selected concurrently:

https://github.com/yonat/MultiSelectSegmentedControl

This one is a subclass of UISegmentedControl, which is convenient. I've forked it here:

https://github.com/stewartmacdonald/MultiSelectSegmentedControl

and added some code examples to the ReadMe and added a method that allows you to get an NSArray of the titles of all selected segments.
