iPhone/目标C:如何从NIB获取UIButton实例 [英] iPhone/Objective C: How can I get the UIButton instance from NIB

问题描述

我在笔尖上放置了1个UIButton，当用户单击此按钮时，一个IBAction方法使用 Status 参数连接到它.

I placed 1 UIButton on nib, and when user click this button,an IBAction method connect to it with a Status param.

我想要的是，用户单击按钮并将状态传递给IBAction方法，在该方法中，我需要访问按钮的实例.

What I want is, user click button and pass the Status to the IBAction method, and in that method, I need access the instance of the button.

如何在没有(id)发送者的情况下获取按钮的实例?

How can I get the button's instance without an (id) sender here?

推荐答案

您可以像使用IBAction进行连接那样，将UIButton与插座连接起来.

You can wire up the UIButton with an outlet like you did with your IBAction to connect it.

在标题中添加:

UIButton *myButton;

...

@property (nonatomic, retain) IBOutlet UIButton *myButton;

然后将新插座与您在IB中的按钮链接.

And then link the new outlet with your button in IB.

然后，您可以在实例中使用myButton访问该按钮.

Then you can access the button with myButton in your instance.
