how to perform a segue
提问by chizzle
I would like implement a button to show another view. I have defined the destination ViewController in Storyboard & created a segue (of type push) and gave it an identifier.
我想实现一个按钮来显示另一个视图。我已经在 Storyboard 中定义了目标 ViewController 并创建了一个 segue（类型为 push）并给了它一个标识符。
In my root view controller
在我的根视图控制器中
some method ...
某种方法...
UIButton *btn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[btn addTarget:self action:@selector(showDetailView:) forControlEvents:UIControlEventTouchUpInside];
and
和
- (IBAction)showDetailView:(id)sender {
[self performSegueWithIdentifier:@"ShowDetail" sender:sender];
}
however it doesn't do anything. I hear a Segue is an object. do I need to have a reference to it / synthesize it in my root view controller class? Any tip would be appreciated. Thank you.
但是它没有做任何事情。我听说 Segue 是一个对象。我需要在我的根视图控制器类中引用它/合成它吗？任何提示将不胜感激。谢谢你。

Edit:
Make sure your root view controller is embedded in a navigation controller. if it isn't, select your view controller in the storyboard designer and choose Editor->Embed In->Navigation Controller in the menu.
编辑：
确保您的根视图控制器嵌入在导航控制器中。如果不是，请在故事板设计器中选择您的视图控制器，然后在菜单中选择 Editor->Embed In->Navigation Controller。
Original:
Double-check the Identifier (storyboard-code) and try setting senderto self. If that doesn't work you can create a Segue object yourself in code.
原文：
仔细检查标识符（故事板代码）并尝试设置sender为self. 如果这不起作用，您可以自己在代码中创建一个 Segue 对象。
