Presenting Modal View Controller programmatically in Swift
提问by user3188157
In the main screen of my iOS application I have a table view populated with a list of users from a web service, what I want to do is to show the table, and over it a modal view controller. I have everything set up, but I don't know how to present my "ModalVC" programatically from the main screen, and to do it after the table was populated? The code below is for presenting a normal view controller programmatically.
在我的 iOS 应用程序的主屏幕中，我有一个表格视图，其中填充了来自 Web 服务的用户列表，我想要做的是显示表格，并在它上面显示一个模态视图控制器。我已设置好所有内容，但我不知道如何从主屏幕以编程方式显示我的“ModalVC”，以及如何在填充表格后执行此操作？下面的代码用于以编程方式呈现一个普通的视图控制器。
let vc : AnyObject! = self.storyboard!.instantiateViewControllerWithIdentifier("ModalVC")
self.showViewController(vc as! UIViewController, sender: vc)
