Requirements

• iOS 11.0 +
• Swift 5.﹡
• XCode 10 +

Installation

ExpandedTabBar doesn't contain any external dependencies.

These are currently the supported intllation options:

CocoaPods

To integrate ExpandedTabBar into your Xcode project using CocoaPods, specify it in your Podfile:

use_frameworks!

target '
   
    '
    do
    pod 'ExpandedTabBar'
end

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but appstore-card-transition does support its use on supported platforms.

Once you have your Swift package set up, adding ExpandedTabBar as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/yervandsar/ExpandedTabBar", from: "3.0.1")
]

Or you can checkout Adding Package Dependencies to Your App by Apple

Flow Setup

• With Storyboard

1. Create UITabBarController
2. Extend from ExpandedTabBarController
3. Set to UITabBarController in storyboard

• Programmatically

let viewControllers: [UIViewController] = [...] // Array of view controllers for UITabBarController
let expandedTabBar = ExpandedTabBarController()
expandedTabBar.setup(viewControllers: viewControllers)

NOTE: any UIViewController in viewControllers array must have tabBarItem.

Delegation

For tab selection action implement ExpandedTabBarControllerDelegate:

func expandedTabBarController(
    _ tabBarController: UITabBarController,
    didSelect viewController: UIViewController,
    withItem tabBarItem: UITabBarItem?
)

Customization

• More Tab

You can customize more tab in storyboard, or set programmatically.

moreTitle        : String   // Default "More"
moreIcon         : UIImage? // Default Image from SystemItem.More
moreSelectedIcon : UIImage? // Default nil

• Dark Mode Support

ExpandedTabBar is fully Light/Dark mode supported and for setting any UIColor or CGColor you can use.

let color: UIColor/CGColor = .pattern(light: UIColor, dark: UIColor)

NOTE: If device OS version does not support dark mode, it will take light as default.

• Options Customization

ExpandedTabBar options conforms to Options protocol.

public  protocol  Options {
    var  background   : BackgroundOptions
    var  container    : ContainerOptions
    var  animationType: AnimationType
    var  indicatorType: IndicatorTypes
}

Background Options

public protocol  BackgroundOptions {
    var color     : UIColor // Default .clear
    var alpha     : CGFloat // Default 0.3
    var closeOnTap: Bool    // Default true
}

Container Options

public protocol  ContainerOptions {
    var color         : UIColor             // Default .pattern(light: .white, dark: .black)
    var alpha         : CGFloat             // Default 1.0
    var cornerRadius  : CGFloat             // Default 10
    var roundedCorners: UIRectCorner        // Default .allCorners
    var bottomMargin  : CGFloat             // Default 15
    var tabSpace      : CGFloat             // Default 8
    var tab           : ContainerTabOptions
    var shadow        : ShadowOptions?      // Default nil
}

NOTE: For shadow you can see and use ShadowDefaultOptions class

Container's Tab Options

public protocol  ContainerTabOptions {  
    var itemHeight     : CGFloat.           // Default 35
    var titleFont      : UIFont             // Default .systemFont(ofSize: 16)
    var titleColor     : UIColor            // Default .pattern(light: .black, dark: .white)
    var iconColor      : UIColor            // Default .pattern(light: .black, dark: .white)
    var iconContentMode: UIView.ContentMode // Default .scaleAspectFit
    var iconTitleSpace : CGFloat            // Default 8
}

Animation Types

NoneAnimations	Translate	Zoom	Rotate
.none	.top Default	.zoomIn	.rotatePositive
.crossDissolve	.bottom	.zoomOut	.rotateNegative
	.left	.zoomX	.rotate(angle: .pi/6)
	.right	.zoomY

NOTE: You can create your own animation .custom(AnimationProtocol). You can use TransformAnimation for creating custom animations

Indicator Types

.none	.connectedLine	.triangle Default

Examples

final class CustomViewController: ExpandedTabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()
        expandedDelegate = self
        expandedTabBarOptions = customOptions
        
    }
    
    private var customOptions: Options {
        var options = ExpandedTabBarOptions()
        
        options.indicatorType = .connectedLine
        options.animationType = .custom(customAnimation)
        
        options.container.roundedCorners = [.topLeft, .topRight, .bottomLeft]
        options.container.cornerRadius = 20
        
        options.container.shadow = ShadowDefaultOptions()
        options.container.tabSpace = 15
        options.container.tab.iconTitleSpace = 15
        
        return options
    }
    
    private var customAnimation: AnimationProtocol {
        let transform = CGAffineTransform(scaleX: 0.1, y: 0.1).rotated(by: .pi)
        return TransformAnimation(transform: transform)
    }
    
}

extension  CustomViewController: ExpandedTabBarControllerDelegate {

    func expandedTabBarController(_ tabBarController: UITabBarController,
                                    didSelect viewController: UIViewController,
                                    withItem tabBarItem: UITabBarItem?) {
        // Do some logic here
    }
}
