How to navigate to TabBar ViewController on click of button on popover ViewController in swift?

Question

I have TabBarController project, with navigation bar. On navigation bar I have popover on right BarButtonItem . On that popover ViewController I have one button. On that button click I want to move to any TabBarController .

I tried with

tababarController.selectedIndex = 1

But view is not switching

Is there any solution?

Answer 1

您将关闭popover并从主视图控制器中的popover viewcontroller中调用委托方法，然后在委托方法中设置工具栏的选定索引。

Answer 2

setSelectedIndex should work right.

Maybe you are not getting correct reference of your UITabBarController and while checking, you might get it nil.

Answer 3

class PopupviewController {

weak var delegate: NavigateViewDelegate?

func buttonPress () {
   delegate?.navigate()
 }  
}
protocol NavigateViewDelegate : class {
      func navigate()
}
class TabBarViewController :NavigateViewDelegate {

  func navigate() {
    tababarController.selectedIndex = 1   
  }
}
