從標籤欄控制器顯示視圖控制器從另一個選項卡沒有切換選項卡

Question

我有四個視圖控制器嵌入在選項卡欄控制器（如下所示）。我想要顯示來自Feed視圖的配置文件視圖，而無需切換選項卡。任何建議都會很棒。

Answer 1

做的是增加一個 子視圖

這裏是我的代碼，我在我的項目上雨燕2.0

let tabBarController = self.sourceViewController as TabBarController 
let destinationController = self.destinationViewController as UIViewController 

     for view in tabBarController.placeholderView.subviews as [UIView] { 
      view.removeFromSuperview() // 1st remove from superview 
     } 

     // Add view to placeholder view 
     tabBarController.currentViewController = destinationController 
     tabBarController.placeholderView.addSubview(destinationController.view) // 2 

     // Set autoresizing mask so it fits correctly 
     tabBarController.placeholderView.setTranslatesAutoresizingMaskIntoConstraints(false) 
     destinationController.view.setTranslatesAutoresizingMaskIntoConstraints(false) 

     let horizontalConstraint = NSLayoutConstraint.constraintsWithVisualFormat("H:|-0-[v1]-0-|", options: .AlignAllTop, metrics: nil, views: ["v1": destinationController.view]) // 3 

     tabBarController.placeholderView.addConstraints(horizontalConstraint) 

     let verticalConstraint = NSLayoutConstraint.constraintsWithVisualFormat("V:|-0-[v1]-0-|", options: .AlignAllTop, metrics: nil, views: ["v1": destinationController.view]) // 3 

     tabBarController.placeholderView.addConstraints(verticalConstraint) 

     tabBarController.placeholderView.layoutIfNeeded() // 3 
     destinationController.didMoveToParentViewController(tabBarController) // 4 

    } 

這裏測試使用

的最佳方式是我在做自定義tabbar時所指的博客，希望它能幫助你： http://swiftiostutorials.com/tutorial-custom-tabbar-storyboard/
