MultiSelectSegmentedControl

UISegmentedControl remake that supports selecting multiple segments, vertical stacking, combining text and images.

Features

Single or multiple selection.
Horizontal or vertical stacking.
Can show text and images together.
Use from either storyboard or code.
UIAppearance support.

Usage

Very similar to UISegmentedControl, can be used as a drop-in replacement in most cases.

If you use Interface Builder, add a regular UIView and then set its class to MultiSelectSegmentedControl.

SwiftUI Usage

MultiSegmentPicker(
    selectedSegmentIndexes: $indexSet,
    items: ["One", "Two", image, [image2, "Text"], "Last"]
)

The properties mentioned below can be passed as arguments to the MultiSegmentPicker initializer, or used as view modifiers (e.g., .borderWidth(3)).

Creating Segments

Each segment can contain an image, a text, or both:

let multiSelect = MultiSelectSegmentedControl()
multiSelect.items = ["One", "Two", image, [image2, "Text"], "Last"]

Images are shown in full color (unlike UISegmentedControl). To make them render in the same tintColor as the control, use template mode:

multiSelect.items = [image1, image2, image3].map { $0.withRenderingMode(.alwaysTemplate) }

Selecting Segments

multiSelect.selectedSegmentIndexes = [1, 2, 4]

Or just single selection:

multiSelect.allowsMultipleSelection = false
multiSelect.selectedSegmentIndex = 3

Getting Selected Segments

let selectedIndices: IndexSet = multiSelect.selectedSegmentIndexes

Or to get the titles:

let titles: [String] = multiSelect.selectedSegmentTitles

Handling User Selection Changes

You can use standard target-action:

multiSelect.addTarget(self, action: #selector(selectionChanged), for: .valueChanged)

Or conform to the delegate protocol:

extension MyViewController: MultiSelectSegmentedControlDelegate {
    func multiSelect(_ multiSelectSegmentedControl: MultiSelectSegmentedControl, didChange value: Bool, at index: Int) {
        print("selected \(value) at \(index)")
    }
}

... and set the delegate:

multiSelect.delegate = self

Changing Appearance

Color:

multiSelect.tintColor = .green

Background Color (optional - use if background color should be different from tint color):

multiSelect.selectedBackgroundColor = .blue

Shape:

multiSelect.borderWidth = 3 // Width of the dividers between segments and the border around the view.
multiSelect.borderRadius = 32 // Corner radius of the view.

Stack the segments vertically:

multiSelect.isVertical = true

Stack each segment contents vertically when it contains both image and text:

multiSelect.isVerticalSegmentContents = true

Text styling:

multiSelect.setTitleTextAttributes([.foregroundColor: UIColor.yellow], for: .selected)
multiSelect.setTitleTextAttributes([.obliqueness: 0.25], for: .normal)

More label styling:

multiSelect.titleConfigurationHandler = {
    $0.numberOfLines = 0
    $0.lineBreakMode = .byWordWrapping
}
