实例化视图控制器 Swift 3 标签栏控制器 [英] Instantiate View Controller Swift 3 Tab Bar Controller

问题描述

如何转到标签栏控制器?标签上有 2 个视图控制器，带有导航控制器，标签栏控制器上有一个导航控制器.

How can I segue to a tab bar controller? Theres 2 view controllers on tabs with navigation controllers and a navigation controller on the tab bar controller.

let storyboard = UIStoryboard(name: "PendingOverview", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "PendingOverviewVC") as! PendingOverViewController
let nc = UINavigationController(rootViewController: vc)
self.present(nc, animated: false, completion: nil)

谢谢

推荐答案

在 Storyboard 中将 identifier 设置为 UITabbarController 然后使用 instantiateViewController 表示UITabbarController.

In Storyboard set identifier to UITabbarController and then using instantiateViewController present that UITabbarController.

let storyboard = UIStoryboard(name: "PendingOverview", bundle: nil)
let tabbarVC = storyboard.instantiateViewController(withIdentifier: "TabbarIdentifier") as! UITabbarController
if let vcs = tabbarVC.viewControllers, 
   let nc = vcs.first as? UINavigationController,
   let pendingOverVC = nc.topViewController as? PendingOverViewController {

      pendingOverVC.pendingResult = pendingResult
}
self.present(tabbarVC, animated: false, completion: nil)
