A custom tab bar controller for iOS written in Swift 4.2

Hello - the tabBar is working well. Just curious if there was a way to add a black shadow extending from the top border into the view. This code has no effect...

tabController.view.layer.shadowColor = UIColor.black.cgColor tabController.view.layer.masksToBounds = false tabController.view.layer.shadowOffset = CGSize.zero tabController.view.layer.shadowRadius = 50 tabController.view.layer.shadowOpacity = 1.0

Thanks!

hi i am using AZTabBarController as a pod in my project, in myviewDidLoad of Main VC i have : tabController.set(viewController: instanceControllerAccount, atIndex: 1)

but it show nothing except the selector indicator shifting to that tab

I have six tabItem view controller, each child view controller has own a navigation controller itself. I have a problem to push a new view controller after change the selectedIndex.

//the viewcontroller I want to push let vc = self.storyboard?.instantiateViewController(withIdentifier: "CreateArticleViewController") as! CreateArticleViewController self.currentTabBar?.setIndex(3, animated: true) // Below code doesn't work self.navigationController?.pushViewController(vc, animated: true) self.currentnavigationController?.pushViewController(vc, animated: true)

tabcontroller -> Navigation 1 -> A1 -> A2
-> Navigation 2 -> B1 -> B2 -> B3 -> B4 -> Navigation 3 -> C1 -> C2 -> C3 -> C4 -> Navigation 4 -> D1 -> D2 -> D3 -> D4 -> Navigation 5 -> E1 -> E2 -> E3 -> Navigation 6 -> F1 -> F2 -> F3

For example, when I in A1, how do I change the index and push the view controller to D3? I also want my tabbar be more transparent. I can change background color perfectly but alpha doesn't work. How to set the AZTabBarController alpha?

Good day Sir @Minitour I am a graphics designer and i want to contribute to your project by designing a logo for it as i have noticed it doesn't have one yet. I will be gladly doing it as a gift for free if you will permit me. Thanks and best regards! - Tobaloidee

Hello, I love your library but i couldn't implement it on my project. Can you create a better version of USAGE part ? :) I'm new at iOS and i cannot find how to create AZTabBarController. I really want to use your library.

Thank you :)

I tried to create a UIBarButtonItem by using

controller.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "xxx", style: .plain, target: self, action:xxx)

But the item failed to be created, and I tried with both the AZTabBarController and one of the tab controllers.

A little help would be much appreciated~

Hi, awesome library - love it!! I'm a bit new to Swift and I need a bit of help. I need to be able to set the badge text from the other view controllers. Each view controller is responsible for updating separate pieces of info from the server, so they need to be able to set their badges. I tried making the tabController public, then saying self.parent.tabController from the child view controller - which WOULD work, except that I have no idea how to declare the tabController correctly as a public. It seems to require icons, etc, which I can't give outside viewDidLoad. Can you offer any guidance on this?

Thanks!

How can I set tab bar icon images without any default or selected color? I just want their images to be displayed for both default and selected status.

I am trying to set different images in TabBar but just one image from them doesn't work.

    var icons = [UIImage]()
    icons.append(UIImage(named: "ic_tab_wallpaper")!)
    icons.append(UIImage(named: "ic_tab_maps")!)
    icons.append(UIImage(named: "ic_tab_wallpaper")!)
    icons.append(UIImage(named: "ic_tab_shop")!)
    icons.append(UIImage(named: "ic_tab_profile")!)
    
    var sIcons = [UIImage]()
    sIcons.append(UIImage(named: "ic_tab_wallpaper_selected")!)
    sIcons.append(UIImage(named: "ic_tab_maps")!)
    sIcons.append(UIImage(named: "ic_tab_wallpaper_selected")!)
    sIcons.append(UIImage(named: "ic_tab_shop_selected")!)
    sIcons.append(UIImage(named: "ic_tab_profile_selected")!)

Every other image except ic_tab_maps works and shows in TabBar. I have tried to check in your example as well but it doesn't work.

Initially, I thought the problem is within my app, but then I tried the example, which has the same issue. Basically, when a user clicks multiple times on the buttons it seems that sometimes the toggle fails. Sometimes the app switches to a completely different view (usually the home).

A way to replicate the behavior would be to click on the "feed" tab, from the example project, in multiple succession (almost like rage clicking it).

I assume this is due to the views being stacked on top of each other. I don't really know what's going on.

Another issue that I'm facing is that the AZTabController seems to be on top of everything in my view and screws up element interaction. There is another issue related to this bug but the suggestion didn't solve my problem. Seems like the TabController is messing up the NavigationController.

Better documentation will be really helpful...

Hi there,

I followed the usage tutorial on the ReadMe exactly and my app seems to crash, here is the exception:

And here is how I use the AZTbarBar:

    var icons = [String]()
    icons.append("document")
    icons.append("group")
    icons.append("compass")
    icons.append("cogwheel")

    var selectedIcons = [String]()
    selectedIcons.append("document_selected")
    selectedIcons.append("group_selected")
    selectedIcons.append("compass_selected")
    selectedIcons.append("cogwheel_selected")
    
    tabController = AZTabBarController.insert(into: self, withTabIconNames: icons, andSelectedIconNames: selectedIcons)
    
    let documentsPage = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "documentsViewController")
    let groupPage = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "groupViewController")
    let findPage = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "findViewController")
    let settingsPage = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "settingsViewController")
    
    tabController.setViewController(documentsPage, atIndex: 0)
    tabController.setViewController(groupPage, atIndex: 1)
    tabController.setViewController(findPage, atIndex: 2)
    tabController.setViewController(settingsPage, atIndex: 3)

It seems crash when the AZTabBarController.insert() line is hit

How can I move to specific tab controllers detail page on click of notification. Like If I had Chat thread on first index tap and I need to navigate in chat screen on notification click.

I have 5 tab bar item, each tab bar button have navigation controller. If I tap in second tab item and push maybe three or four view controller, then I tap another tab item and return two second tab item. Can I reset this navigation controller( second tab item ) to first view controller, or I need to pop view controller manually? Thank you.

Hi, I use the tab bar and hide it in my main view(first tab), and use self.currentTabBar?.setBar(hidden: false, animated: false) in main view's viewDidDissapear(). I also set some segment with button bar in other tab view. The issue is that my button bar reset to the first segment position. My button bar works fine when I change tab with tapping tab bar. I try many times and found that issue supposedly happen when tabBar hidden is changing. Is some way to correct this issue? Demo video: https://youtu.be/V6lD-40gNpw

extension UISegmentedControl {
    func setButtonBar(buttonBar: UIView){
        buttonBar.translatesAutoresizingMaskIntoConstraints = false

        buttonBar.topAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
        buttonBar.heightAnchor.constraint(equalToConstant: 1).isActive = true
        buttonBar.leftAnchor.constraint(equalTo: self.leftAnchor, constant: (self.frame.width /         CGFloat(self.numberOfSegments)) * CGFloat(self.selectedSegmentIndex)).isActive = true
        buttonBar.widthAnchor.constraint(equalTo: self.widthAnchor, multiplier: 1 / CGFloat(self.numberOfSegments)).isActive = true
    }


    func moveButtonBar(buttonBar: UIView){
        print("movebuttonBar")
        UIView.animate(withDuration: 0.4) {
            buttonBar.frame.origin.x = (self.frame.width / CGFloat(self.numberOfSegments)) * CGFloat(self.selectedSegmentIndex) + self.frame.origin.x

I would like a tab bar that is less than the width of the screen. How can I adjust the width? Interesting for example to imitate the Apple Music application on iPad ... Thanks.

Hi. I have successfully make a corner radius to containerView of aTabbar. But the issue is when we set up the controller for tab, due to navigation controller it just didn't work when we don't have any table view there.

With TableView, you can check radius at top left and top right

With ImageView,
