WKInterfaceTable中的WKInterfaceButton事件处理

问题描述

我有 WKInterfaceTable 表格视图，其中包含 WKInterfaceButton 。

I have a WKInterfaceTable table view with a WKInterfaceButton.

如何从表格视图向按钮添加目标操作。由于没有标签属性，我无法处理它。

How can I add a target action to the button from the table view. As there is no tag property I am not able to handle it.

推荐答案

如果你的 WKInterfaceButton 包含在行控制器中，这里是确定点击哪一行按钮的一种方法：

If your WKInterfaceButton is contained within a row controller, here is one method to determine which row's button was tapped:

• 将 WKInterfaceButton 添加到行控制器和使用界面构建器将按钮的操作连接到行控制器类


• 向行控制器添加一个属性，允许您引用数据（例如，对您的数据的弱引用）数据或标记）


• 向行控制器添加属性，允许您将接口控制器设置为委托


• 为此创建协议允许您传递数据引用的委托


• 初始化每个行控制器时，请务必设置数据和委托属性



• 按钮操作在行控制器中处理，调用您在协议中定义的委托方法。类似于：

• Add your WKInterfaceButton to the row controller and use interface builder to connect the button's action to your row controller class
• Add a property to your row controller that allows you to reference your data (for example, a weak reference to your data or a tag)
• Add a property to your row controller that allows you to set your interface controller as a delegate
• Create a protocol for the delegate that allows you to pass the data reference
• When initializing each row controller, be sure to set the data and delegate properties

• When the button action is handled in the row controller, call the delegate method that you defined in your protocol. Something like:

- （void）rowController：（MyRowControllerClass *）rowController didSelectRowWithTag：（NSInteger）tag

在接口控制器中处理此委托方法，以执行必要的工作。

Handle this delegate method in your interface controller to do whatever work is necessary.

我在自己的Watch应用程序中使用这种技术，效果非常好。

I use this technique in my own Watch app, and it works very well.
