Swift ESTabBarController large center button fail

Question

I download and run ESTabBarController fine but I don't know why when I create my own project and use code from Example, my large button still small??

While image below is from example project as my expectation as well Here is my code

AppDelegate.swift

let TabbarNavigationController = ViewController.customIrregularityStyle(delegate: nil)
self.window?.rootViewController = TabbarNavigationController    

ViewController.swift

static func customIrregularityStyle(delegate: UITabBarControllerDelegate?) -> NavigationController {
    let tabBarController = ESTabBarController()
    tabBarController.delegate = delegate
    tabBarController.title = "Irregularity"
    tabBarController.tabBar.shadowImage = UIImage(named: "transparent")
    tabBarController.tabBar.backgroundImage = UIImage(named: "background_dark")
    tabBarController.shouldHijackHandler = {
        tabbarController, viewController, index in
        if index == 2 {
            return true
        }
        return false
    }
    tabBarController.didHijackHandler = {
        [weak tabBarController] tabbarController, viewController, index in

        DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
            let alertController = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)
            let takePhotoAction = UIAlertAction(title: "Take a photo", style: .default, handler: nil)
            alertController.addAction(takePhotoAction)
            let selectFromAlbumAction = UIAlertAction(title: "Select from album", style: .default, handler: nil)
            alertController.addAction(selectFromAlbumAction)
            let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
            alertController.addAction(cancelAction)
            tabBarController?.present(alertController, animated: true, completion: nil)
        }
    }

    let v1 = ExampleViewController()
    let v2 = ExampleViewController()
    let v3 = ExampleViewController()
    let v4 = ExampleViewController()
    let v5 = ExampleViewController()

    v1.tabBarItem = ESTabBarItem.init(IrregularityBasicContentView(), title: "Home", image: UIImage(named: "home"), selectedImage: UIImage(named: "home_1"))
    v2.tabBarItem = ESTabBarItem.init(IrregularityBasicContentView(), title: "Find", image: UIImage(named: "find"), selectedImage: UIImage(named: "find_1"))
    v3.tabBarItem = ESTabBarItem.init(IrregularityBasicContentView(), title: nil, image: UIImage(named: "photo_verybig"), selectedImage: UIImage(named: "photo_verybig"))
    v4.tabBarItem = ESTabBarItem.init(IrregularityBasicContentView(), title: "Favor", image: UIImage(named: "favor"), selectedImage: UIImage(named: "favor_1"))
    v5.tabBarItem = ESTabBarItem.init(IrregularityBasicContentView(), title: "Me", image: UIImage(named: "me"), selectedImage: UIImage(named: "me_1"))

    tabBarController.viewControllers = [v1, v2, v3, v4, v5]

    let navigationController = NavigationController.init(rootViewController: tabBarController)
    tabBarController.title = "Example"
    return navigationController
}

Any idea?

Try to use custom tabBar and add your button in centre of tabBar Like This

If you want to use ESTabBarController follow the below steps.

Step 1: Download the sample project of ESTabBarController and install pod "ESTabBarController-swift" in your project

Step 2: Copy all the assets from sample project into your existing project

Step 3: Copy ExampleBasicContentView, ExampleBouncesContentView , ExampleIrregularityContentView, ExampleNavigationController Classes from sample project

NOTE - If you got error “No such module 'pop'” in “ExampleIrregularityBasicContentView” Then remove that line and remove func playMaskAnimation Or install pod pop

Step 4: In StoryBoard Embbed your viewController in navigationController and assign ExampleNavigationController class to your navigationController

Step 5: import ESTabBarController_swift and add UITabBarControllerDelegate in your AppDelegate class Add paste following code in your AppDelegate class

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {


        let tabBarController = ESTabBarController()
        tabBarController.delegate = self
        tabBarController.tabBar.shadowImage = UIImage(named: "transparent")
        tabBarController.tabBar.backgroundImage = UIImage(named: "background_dark")

        tabBarController.shouldHijackHandler = {
            tabbarController, viewController, index in
            if index == 2 {
                return true
            }
            return false
        }

        tabBarController.didHijackHandler = {
            [weak tabBarController] tabbarController, viewController, index in

            DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
                let alertController = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)
                let takePhotoAction = UIAlertAction(title: "Take a photo", style: .default, handler: nil)
                alertController.addAction(takePhotoAction)
                let selectFromAlbumAction = UIAlertAction(title: "Select from album", style: .default, handler: nil)
                alertController.addAction(selectFromAlbumAction)
                let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
                alertController.addAction(cancelAction)
                tabBarController?.present(alertController, animated: true, completion: nil)
            }
        }

        let v1 = ViewController()
        let v2 = ViewController()
        let v3 = ViewController()
        let v4 = ViewController()
        let v5 = ViewController()

        v1.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Home", image: UIImage(named: "home"), selectedImage: UIImage(named: "home_1"))
        v2.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Find", image: UIImage(named: "find"), selectedImage: UIImage(named: "find_1"))
        v3.tabBarItem = ESTabBarItem.init(ExampleIrregularityContentView(), title: nil, image: UIImage(named: "photo_verybig"), selectedImage: UIImage(named: "photo_verybig"))
        v4.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Favor", image: UIImage(named: "favor"), selectedImage: UIImage(named: "favor_1"))
        v5.tabBarItem = ESTabBarItem.init(ExampleIrregularityBasicContentView(), title: "Me", image: UIImage(named: "me"), selectedImage: UIImage(named: "me_1"))

        tabBarController.viewControllers = [v1, v2, v3, v4, v5]

        let navigationController = ExampleNavigationController.init(rootViewController: tabBarController)
        self.window?.rootViewController = navigationController

         return true
    }
