以编程方式将ViewController呈现在其他控件之上 [英] Present ViewController on top of other programmatically

问题描述

我有以下代码显示了我的视图控制器，而不是现有的视图控制器:

I have the following code which present my viewcontroller instead of an existing one:

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)

但是我想以编程方式在另一个视图的顶部显示视图控制器，

But I want to present the viewcontroller on top of the other one programmatically,

有什么想法吗?

推荐答案

如果希望看到模态视图控制器，尽管必须为其视图提供clear color背景.并将其modalPresentationStyle设置为.OverCurrentContext.

If you want your modal view controller to be see-though you have to give its view a clear color background. And set its modalPresentationStyle to .OverCurrentContext.

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

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