ios - Swift 选项卡式应用程序多次使用相同的 UIViewController

Question

我需要一种方法将同一 UIViewController 的实例(从我的 Storyboard)多次添加到 tabbarcontroller

不确定最好的方法是什么

Answer 1

在同一个 View Controller 上创建不同的实例并添加到标签栏 Controller 。

let vc = self.storyboard.instantiateViewControllerWithIdentifier(“storyboard_id”) as yourViewcontroller
vc.tabBarItem = UItabbarItem(Title:“title” image:image tag:yourtag);

let vc1 = self.storyboard.instantiateViewControllerWithIdentifier(“storyboard_id”) as yourViewcontroller
vc1.tabBarItem = UItabbarItem(Title:“title1” image:image1 tag:yourtag);

tabbarController.setViewControllers([vc,vc1]);
