如何执行segue [英] how to perform a segue

问题描述

我想实现一个按钮来显示另一个视图。我在Storyboard&中定义了目标ViewController。创建了一个segue（类型为push）并给它一个标识符。

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.

在我的根视图控制器中

一些方法...

        UIButton *btn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        [btn addTarget:self action:@selector(showDetailView:) forControlEvents:UIControlEventTouchUpInside];

和

- (IBAction)showDetailView:(id)sender {
    [self performSegueWithIdentifier:@"ShowDetail" sender:sender];
}

但它没有做任何事情。我听说Segue是一个对象。我是否需要在根视图控制器类中引用它/合成它？任何提示将不胜感激。谢谢。

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.

确保您的根视图控制器是嵌入式的在导航控制器中。如果不是，请在情节提要设计器中选择视图控制器，然后在菜单中选择编辑器 - >嵌入 - >导航控制器。

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.

仔细检查标识符（故事板代码）并尝试将发件人设置为 self 。如果这不起作用，你可以自己在代码中创建一个Segue对象。

Original:
Double-check the Identifier (storyboard-code) and try setting sender to self. If that doesn't work you can create a Segue object yourself in code.
