This is a control for iOS written in Swift. DTPagerController is simple to use and easy to customize.


Default segmented control

Custom segmented control


DTPagerController is extremely easy to use. In order to display two view controllers inside a pager controller. All you have to do is this many lines of code.

let viewController1 = ViewController()
let viewController2 = ViewController()
let pagerController = DTPagerController(viewControllers: [viewController1, viewController2])

Update page index

There are 3 different ways to update selected page index programmatically.

// Update selected page index with animation
pagerController.selectedPageIndex = 1

// Update selected page index with animation
pagerController.setSelectedPageIndex(1, animated: true)

// Update selected page index without animation
pagerController.setSelectedPageIndex(1, animated: false)

Custom UI

DTPagerController is also customizable in case you want to implement your own UI.

// Change the height of segmented control
pagerController.preferredSegmentedControlHeight = 60

// Change normal font of each segmented control
pagerController.font = UIFont.customFont(ofSize: 15)

// Change selected font of each segmented control
pagerController.selectedFont = UIFont.boldCustomFont(ofSize: 15)

// Change normal text color of each segmented control
pagerController.textColor = UIColor.black

// Change selected text color of each segmented control
pagerController.selectedTextColor = UIColor.red

// Change scroll indicator height
pagerController.perferredScrollIndicatorHeight = 3

Custom segmented control

From version 2.0.0, DTPagerController supports custom segmented control. Therefore, instead of using default DTSegmentedControl, you can provide your own segmented control or any 3rd-party segmented control libraries available out there. All you have to do is making your custom UIControl conform DTSegmentedControlProtocol. For example, as shown in sample project, HMSegmentedControl is made to conform DTSegmentedControlProtocol by using extension:

extension HMSegmentedControl: DTSegmentedControlProtocol {

    public func setImage(_ image: UIImage?, forSegmentAt segment: Int) {
        // Custom page control does not support

    public func setTitle(_ title: String?, forSegmentAt segment: Int) {
        // Custom page control does not support

    public func setTitleTextAttributes(_ attributes: [AnyHashable : Any]?, for state: UIControlState) {
        if state == UIControlState.normal {
            titleTextAttributes = attributes
        else if state == UIControlState.selected {
            selectedTitleTextAttributes = attributes


Then we create new pager controller with the custom segmented control:

init(viewControllers controllers: [UIViewController]) {
        let segmentedControl = HMSegmentedControl(sectionTitles: ["Page 1", "Page 2", "Page 3"])
        super.init(viewControllers: controllers, pageSegmentedControl: segmentedControl!)

When using custom segmented control, it is recommneded to override/take a look at the following methods to customize behavior and appearance of each segments:

// Setup custom segmented control
func setUpSegmentedControl(viewControllers: [UIViewController])

// Update a custom appearance for segment
func updateAppearanceForSegmentedItem(at index: Int)

// Update a custom scroll indicator if exists
func updateScrollIndicator(with offsetRatio: CGFloat, scrollView: UIScrollView)

// Setup custom scroll indicator
func setUpScrollIndicator()

// Manually update segment title
func setTitle(_ title: String?, forSegmentAt segment: Int)

// Manually update segment image
func setImage(_ image: UIImage?, forSegmentAt segment: Int)


To run the example project, clone the repo, and run pod install from the Example directory first.
