ios - 以编程方式将 ViewController 呈现在其他之上

Question

我有以下代码显示我的 View Controller 而不是现有的:

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)

但我想以编程方式在另一个 View Controller 的之上呈现 View Controller ，

有什么想法吗？

Answer 1

如果你想让你的模态视图 Controller 可见，尽管你必须给它的 View 一个清晰的颜色背景。并将其 modalPresentationStyle 设置为 .OverCurrentContext。

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

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