Get selected index tabbar controller Swift

我的未来我决定 提交于 2019-12-06 02:33:23

application.tabBarController is an optional, this means it can be nil. If you are sure it will never be nil, do this:

var selectedIndex = tabBarController!.selectedIndex

you should try this:

let application = UIApplication.shared.delegate as! AppDelegate
let tabbarController = application.window?.rootViewController as! UITabBarController
let selectedIndex = tabbarController.selectedIndex
