以編程方式呈現ViewController

Question

我有以下代碼，它呈現我的viewcontroller 而不是現有的：

let frameworkBundle = NSBundle(identifier: "me.app.MyFramework")
var storyBoard:UIStoryboard = UIStoryboard(name: "MyStoryboard", bundle: frameworkBundle)

var vc = storyBoard.instantiateInitialViewController() as MyPresenterViewController

viewControllerToPresentIn.presentViewController(vc, animated: true, completion: nil)

但我想以編程方式將viewcontroller呈現在另一個上面 ，

有任何想法嗎？

Answer 1

如果您希望查看模態視圖控制器，則必須為其視圖提供clear color背景。 並將其modalPresentationStyle設置為.OverCurrentContext 。

let vc = storyBoard.instantiateInitialViewController() as! MyPresenterViewController
vc.view.backgroundColor = .clearColor()
vc.modalPresentationStyle = .OverCurrentContext

viewControllerToPresentIn.presentViewController(vc, animated: true, completion: nil)

Answer 2

我使用以下方法，以便僅在另一個視圖控制器的底部顯示我的視圖：

var presenterStoryBoard:UIStoryboard = UIStoryboard(name: "MiniAppPanel", bundle: frameworkBundle)

var vc = presenterStoryBoard.instantiateInitialViewController() as MiniAppPanelViewController

vc.view.frame = CGRectMake(0, vc.view.frame.size.height - 120, vc.view.frame.size.width, 120)

publisherViewController.addChildViewController(vc)    
publisherViewController.view.addSubview(vc.view)

Answer 3

如果您使用navigationcontroller，則可以將viewcontrollers更改為

    navigationController?.presentViewController(newVC, animated: true, completion: nil)

但由於呈現不會從左或右帶來視圖，您將丟失導航控制器
