I have a tab bar application and i have a button on my first view which i want to when pressed switch to my second tab programmatically in the tab bar.
I can't quite seem to figure it out how to get the index etc to switch to it i've tried stuff like this.
tababarController.selectedIndex = 1 With no success.

backgroundColor = UIColor(red:1, green:0, blue:0, alpha:1) / UITabBar. appearance(). tintColor = UIColor(red: 1, green: 0, blue: 0, alpha: 1) // New!! func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {...}
What's A Tab Bar Controller? A tab bar controller, of class UITabBarController, is a container view controller. It typically organizes 3-5 view controllers in a group. The user of your app can switch between view controllers by tapping one of the tabs in the tab bar at the bottom of the screen.
Thats pretty simple tabBarController is declared as an optional type
var tabBarController: UITabBarController? { get } The nearest ancestor in the view controller hierarchy that is a tab bar controller. If the view controller or one of its ancestors is a child of a tab bar controller, this property contains the owning tab bar controller. This property is nil if the view controller is not embedded inside a tab bar controller.
So you just need to add "?" at the end of it:
@IBAction func goToSecond(_ sender: Any) { tabBarController?.selectedIndex = 1 } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
