我怎样才能获得用故事板创建的按钮的对象 [英] how can i get the object of a button created with storyboard

问题描述

我通过拖动故事板中的按钮图标在视图控制器上创建了一个按钮.我认为这会生成一个对象.有没有一种方法可以获取 id，即那个按钮的对象?是否有一种方法可以为该按钮指定标签或标识符，并且我们可以使用某些方法来引用它?提前感谢您的回答.

I created a button on a view controller by dragging the icon of button in storyboard. I thought this would generate an object. is there an approach that I can get the id, i.e. the object of that button? Is there a method that we designate a label or identifier for that button and we can refer to it with certain methods? Thanks in advance for answering.

推荐答案

当您将一个按钮从对象库拖到故事板的场景中时，当该场景在运行时实例化时，将创建与该按钮关联的对象.如果您想引用该对象以便以编程方式与其交互，则可以打开辅助编辑器:

When you drag a button from the object library onto your storyboard's scene, when that scene is instantiated at runtime, the object associated for that button will be created. If you want to have a reference to that object so you can interact with it programmatically, you can open the assistant editor:

如果您告诉助理编辑器自动"选择正确的关联 .h 文件，您将需要确保为您的视图控制器设置自定义类并简化您的生活:

You will want to make sure you set the custom class for your view controller and you simplify your life a little if you tell your assistant editor to "automatically" select choose the right associated .h file:

然后您可以控制从按钮向下拖动(或右键单击拖动)到助理编辑器窗口并创建一个插座(一个IBOutlet)或一个动作(IBAction):

You can then control-drag (or right-click-drag) from the button down to assistant editor window and create either an outlet (an IBOutlet) or an action (an IBAction):

通过这样做，您就可以引用在场景实例化时创建的按钮对象.

By doing that, you then have a reference to the button object that is created when the scene is instantiated.
