实例化View Controller Swift 3标签栏控制器

如何切换到标签栏控制器？ Theres 2在选项卡上查看带有导航控制器和标签栏控制器上的导航控制器的控制器。

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

在Storyboard设置标识符到UITabbarController然后使用instantiateViewController呈现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)
