Swift中的WKInterfaceTable,行控制器和Button操作

标签: swift apple-watch wkinterfacetable

我在Swift中尝试Apple Watch开发时遇到了相当基本的任务问题。我最近收到的似乎是Obj C中问题的完美答案,但我似乎无法翻译它。

我有一个接口控制器,它包含一个包含同一行控制器的多行的表。每行包含两个按钮。当点击按钮时,它的背景图像发生了变化,但是需要在接口控制器类中调用另一个函数,并且该函数需要访问接口控制器类中的类级变量。

表连接到接口控制器。按钮连接到行控制器类。这是我简化的Swift代码。谢谢你看看!

/// MY INTERFACE CLASS ///

class MainBoard: WKInterfaceController {

    @IBOutlet weak var TileGrid: WKInterfaceTable!

    let numRows = 3

    let imageNames =    ["img1","img2","img3"]

    override func awakeWithContext(context: AnyObject?) {
        super.awakeWithContext(context)

        // Configure interface objects here.
        initBoard()
    }

    func initBoard() {                
        self.TileGrid.setNumberOfRows(self.numRows, withRowType: "Row")

        for var i = 0; i < numRows; i++ {

            let tmpImageA = UIImage(named: imageNames[0])
            let tmpImageB = UIImage(named: imageNames[1])

            let rowOfTiles = self.TileGrid.rowControllerAtIndex(i) as Row

            rowOfTiles.backImageA = tmpImageA
            rowOfTiles.backImageB = tmpImageB

        }        
    }

    func doSomething() {
        //this function needs to be called whenever a button is pressed
    }

}

///////MY ROW CONTROLLER CLASS ////////////////////////

class Row : NSObject {

    // At runtime these will be assigned based on the random game board creation
    var backImageA = UIImage(named: "default.png")
    var backImageB = UIImage(named: "default.png")

    @IBOutlet weak var TileA: WKInterfaceButton!
    @IBOutlet weak var TileB: WKInterfaceButton!

    @IBAction func TapTileA() {
        TileA.setBackgroundImage(backImageA)
        //NEED TO CALL FUNCTION DO SOMETHING IN INTERFACE CONTROLLER
    }

    @IBAction func TapTileB() {
        TileB.setBackgroundImage(backImageB)
        //NEED TO CALL FUNCTION DO SOMETHING IN INTERFACE CONTROLLER

    }

}

我最好的答案是在RowController课程中创建代理人,然后在InterfaceController

中实施此代理人

代表可以使用方法buttonOneClickHappenedbuttonTwoClickHappened

然后每个RowController都将委托作为属性,当您创建RowControllers时,调用setDelegate: self,其中self是您的InterfaceController

希望这有帮助。
