import Segmentio

You can initialize a Segmentio instance from code:

var segmentioView: Segmentio!

let segmentioViewRect = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 125)
segmentioView = Segmentio(frame: segmentioViewRect)
view.addSubview(segmentioView)

or

add a UIView instance in your .storyboard or .xib, set Segmentio class and connect IBOutlet:

@IBOutlet weak var segmentioView: Segmentio!

segmentioView.setup(
	content: [SegmentioItem],
	style: SegmentioStyle,
	options: SegmentioOptions?
)

To start with default options you can just pass nil to the options parameter.

segmentioView.setup(
	content: [SegmentioItem],
	style: SegmentioStyle,
	options: nil
)

In order to set items you need to create an array of SegmentioItem instances:

var content = [SegmentioItem]()

let tornadoItem = SegmentioItem(
	title: "Tornado",
	image: UIImage(named: "tornado")
)
content.append(tornadoItem)

You can specify selected item manually:

segmentioView.selectedSegmentioIndex = 0

segmentioView.valueDidChange = { segmentio, segmentIndex in
	print("Selected item: ", segmentIndex)
}

Segmentio can be customized by passing an instance of SegmentioOptions struct:

SegmentioOptions(
            backgroundColor: .white,
            segmentPosition: SegmentioPosition,
            scrollEnabled: true,
            indicatorOptions: SegmentioIndicatorOptions,
            horizontalSeparatorOptions: SegmentioHorizontalSeparatorOptions,
            verticalSeparatorOptions: SegmentioVerticalSeparatorOptions,
            imageContentMode: .center,
            labelTextAlignment: .center,
            segmentStates: SegmentioStates
)

Segment width rely on SegmentioPosition enum. Width can be fixed according to maximum visible items or dynamic according to segment's content size:

enum SegmentioPosition {
    case dynamic
    case fixed(maxVisibleItems: Int)
}

Selection indicator can be customized by passing an instance of SegmentioIndicatorOptions:

SegmentioIndicatorOptions(
            type: .bottom,
            ratio: 1,
            height: 5,
            color: .orange
)

Horizontal borders can be customized by passing an instance of SegmentioHorizontalSeparatorOptions:

SegmentioHorizontalSeparatorOptions(
            type: SegmentioHorizontalSeparatorType.topAndBottom, // Top, Bottom, TopAndBottom
            height: 1,
            color: .gray
)

Separators between segments can be customized by passing an instance of SegmentioVerticalSeparatorOptions:

SegmentioVerticalSeparatorOptions(
            ratio: 0.6, // from 0.1 to 1
            color: .gray
)

In order to set SegmentioStates you need to create a tuple of SegmentioState instances:

SegmentioStates(
            defaultState: SegmentioState(
                backgroundColor: .clear,
                titleFont: UIFont.systemFont(ofSize: UIFont.smallSystemFontSize),
                titleTextColor: .black
            ),
            selectedState: SegmentioState(
                backgroundColor: .orange,
                titleFont: UIFont.systemFont(ofSize: UIFont.smallSystemFontSize),
                titleTextColor: .white
            ),
            highlightedState: SegmentioState(
                backgroundColor: UIColor.lightGray.withAlphaComponent(0.6),
                titleFont: UIFont.boldSystemFont(ofSize: UIFont.smallSystemFontSize),
                titleTextColor: .black
            )
)

We’d be really happy if you sent us links to your projects where you use our component. Just send an email to github@yalantis.com And do let us know if you have any questions or suggestion regarding the animation.

P.S. We’re going to publish more awesomeness wrapped in code and a tutorial on how to make UI for iOS (Android) better than better. Stay tuned!
