BEKCurveTabbar

Full Customizable Tabbar with IBInspectables <img src="https://github.com/behrad-kzm/BEKDesing/blob/master/Images/BEKHeader.png">

A fun replacement for UITabbar. The Component uses Bézier paths.

Example

usage:

You can change the appearance by using Xcode Interface Builder or by using the default config (recommended). BEKCurveTabbarController can be setup with your custom ViewModel that conforms to the BEKTabBarViewModelType protocol. you can set your 'tabbar' to BEKCurveTabbar inside Interface Builder or initiate it programatically in the easiest way possible like this:

Note: BEKCurveTabbarController initiates with .initiate()

Default Config Usage:

        //Initiate your viewControllers
        let firstViewController = UIViewController()
        firstViewController.view.backgroundColor = .red
        firstViewController.tabBarItem = UITabBarItem(tabBarSystemItem: .search, tag: 0)
        let secondViewController = UIViewController()
        firstViewController.view.backgroundColor = .white
        secondViewController.tabBarItem = UITabBarItem(tabBarSystemItem: .favorites, tag: 1)
        let thirdViewController = UIViewController()
        thirdViewController.view.backgroundColor = .blue
        thirdViewController.tabBarItem = UITabBarItem(tabBarSystemItem: .more, tag: 2)
        
        //get instance of BEKCurveTabbarController
        let tabBarViewController = BEKCurveTabbarController.instantiate()
        
        //set viewControllers to the tabbar
        tabBarViewController.setViewControllers([firstViewController, secondViewController, thirdViewController], animated: true)

Customized Config Usage:

Create a new struct that conforms to BEKTabBarViewModelType :

struct MyCustomTabBarViewModel: BEKTabBarViewModelType {
    let heightRatio: CGFloat = CGFloat(TabbarHeightRatios.bestSize.rawValue)
    let containerColor: UIColor = .white
    let hideTitle: Bool = false
    let animationDuration: CGFloat = 0.3
    let animated: Bool = true
    let shadowColor: UIColor = UIColor(red: 0.353, green: 0.784, blue: 1, alpha: 1.0)
    let shadowRadius: CGFloat = 16
    let containerBorderWidth: CGFloat = 1.0
    let containerBorderColor: UIColor = .gray
    let selectedTextColor: UIColor = .yellow
    let selectedTextFont: UIFont = .systemFont(ofSize: 13)
    let normalTextColor: UIColor = .lightGray
    let normalTextFont: UIFont = .systemFont(ofSize: 11)
    let topCornerRadius: CGFloat = TabbarHeightRatios.bestSize.cornerRadius()
    let bottomCornerRadius: CGFloat = 0
    let containerInsets: UIEdgeInsets = TabbarHeightRatios.bestSize.containerInsets()
    let selectionCircleRadius: CGFloat = TabbarHeightRatios.bestSize.circleRadius()
    let selectionCircleBorderWidth: CGFloat = 0.0
    let selectionCircleBorderColor: UIColor = .clear
    let selectionCircleBackgroundColor: UIColor = UIColor(red: 0.353, green: 0.784, blue: 1, alpha: 1.0)
    let textOffset: CGFloat = 0
    init() {}
}

Note: TabbarHeightRatios.bestSize provides you computed values for different iOS environments. (recommended)

Now you just need to pass your viewModel to .setupViewModel(viewModel: BEKTabBarViewModelType) function.

        //1- Initiate your viewControllers
        let firstViewController = UIViewController()
        firstViewController.view.backgroundColor = .red
        firstViewController.tabBarItem = UITabBarItem(tabBarSystemItem: .search, tag: 0)
        let secondViewController = UIViewController()
        firstViewController.view.backgroundColor = .white
        secondViewController.tabBarItem = UITabBarItem(tabBarSystemItem: .favorites, tag: 1)
        let thirdViewController = UIViewController()
        thirdViewController.view.backgroundColor = .blue
        thirdViewController.tabBarItem = UITabBarItem(tabBarSystemItem: .more, tag: 2)
        
        //2- get instance of BEKCurveTabbarController
        let tabBarViewController = BEKCurveTabbarController.instantiate()
        
        //3- Config your own TabBar ViewModel
        let myViewModel = MyCustomTabBarViewModel()
        
        //4- setup TabBar Controller with you viewModel
        tabBarViewController.setupViewModel(viewModel: myViewModel)
        
        //5- set viewControllers to the tabbar
        tabBarViewController.setViewControllers([firstViewController, secondViewController, thirdViewController], animated: true)
        return tabBarViewController
