执行从 Xib 到 ViewContoller 的 segue [英] Perform a segue from an Xib to ViewContoller

问题描述

我有一个带按钮的 Xib 文件.单击按钮时，我想转到另一个视图控制器.我在 StoryBoard 中的视图控制器之间创建了一个 segue 并创建了一个标识符，但似乎无法以编程方式调用它.

I have a Xib file with a button. I want to segue to another view controller when the button is clicked. I've created a segue between the view controllers in StoryBoard and created an identifier, but can't seem to call it programatically.

@IBAction func buttonAction(sender: UIButton)
{
 self.performSegueWithIdentifier("SegueToPostDetail", sender: sender)
}

Xcode 错误是....没有成员 'performSequeWithIdentifier'

Xcode error is "....has no member 'performSequeWithIdentifier'

谢谢！

推荐答案

不能在 Xib 类中调用 performSegueWithIdentifier，只能在 UIViewController 类中调用.所以你有两个解决方案:

You can't call performSegueWithIdentifier in a Xib class, only in a UIViewController class. So you have 2 solutions:

1. 在 UIViewController 中有按钮，当点击按钮时调用 performSegueWithIdentifier.
2. 在 Xib 类中创建一个委托，UIViewController 类实现该委托协议.如何设置一个简单的委托来在两个视图控制器之间进行通信?
