Platform License Swift 2.2.x Carthage compatible

Animated top/bottom segmented control written in Swift.

Check this project on dribbble

Requirements

iOS 8.x, Swift 2.2.x

Installation

CocoaPods

use_frameworks! 

pod 'Segmentio', '~> 1.1.1'

(CocoaPods v1.0.1 or later required. See this blog post for details.)

Carthage

github "Yalantis/Segmentio" ~> 1.1.1

Usage

Import Segmentio module

import Segmentio

Init

You can initialize a Segmentio instance from code:

var segmentioView: Segmentio!

let segmentioViewRect = CGRect(x: 0, y: 0, width: UIScreen.mainScreen().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!

Setup Segmentio

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

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

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

Configuring items

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)

Handling selection

You can specify selected item manually:

segmentioView.selectedSegmentIndex = 0

Handling callback

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

Customization

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

SegmentioOptions(
    backgroundColor: UIColor.whiteColor(),
    maxVisibleItems: 3,
    scrollEnabled: true,
    indicatorOptions: SegmentioIndicatorOptions,
    horizontalSeparatorOptions: SegmentioHorizontalSeparatorOptions,
    verticalSeparatorOptions: SegmentioVerticalSeparatorOptions,
    imageContentMode: UIViewContentMode.Center,
    labelTextAlignment: NSTextAlignment.Center,
    segmentStates: SegmentioStates // tuple of SegmentioState (defaultState, selectState, highlightedState)
)

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

SegmentioIndicatorOptions(
    type: .Bottom,
    ratio: 1,
    height: 5,
    color: UIColor.orangeColor()
)

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

SegmentioHorizontalSeparatorOptions(
    type: SegmentioHorizontalSeparatorType.TopAndBottom, // Top, Bottom, TopAndBottom
    height: 1,
    color: UIColor.grayColor()
)

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

SegmentioVerticalSeparatorOptions(
    ratio: 0.6 // from 0.1 to 1
    color: UIColor.grayColor()
)

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

SegmentioStates(
    defaultState: segmentioState(
        backgroundColor: UIColor.clearColor(),
        titleFont: UIFont.systemFontOfSize(UIFont.smallSystemFontSize()),
        titleTextColor: UIColor.blackColor()
    ),
    selectState: segmentioState(
        backgroundColor: UIColor.orangeColor(),
        titleFont: UIFont.systemFontOfSize(UIFont.smallSystemFontSize()),
        titleTextColor: UIColor.whiteColor()
    ),
    highlightedState: segmentioState(
        backgroundColor: UIColor.lightGrayColor().colorWithAlphaComponent(0.6),
        titleFont: UIFont.boldSystemFontOfSize(UIFont.smallSystemFontSize()),
        titleTextColor: UIColor.blackColor()
    )
)

Let us know!

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!
