MultiSelectSegmentedControl

[][license-url]

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

Features

• [x] Single or multiple selection.
• [x] Horizontal or vertical stacking.
• [x] Can show text and images together.
• [x] Use from either storyboard or code.
• [x] 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
}

Installation

CocoaPods:

pod 'MultiSelectSegmentedControl'

Swift Package Manager:

dependencies: [
    .package(url: "https://github.com/yonat/MultiSelectSegmentedControl", from: "2.3.6")
