swift - WatchOS2 - 如何在选择时使所有行组或每个行组具有不同的颜色？

Question

我试图使其在单击时一行(一行中的一组)变为紫色，单击新行时它变为紫色，而前一行恢复为默认操作系统颜色。

当我选择一行时，它会正确变为紫色，但是当我点击另一行时，前一行不会恢复为正常的黑色行。

我还想更进一步，让 5 行每行变成不同的颜色。当选择新行时，每个行组都会恢复为默认的 watchOS 黑色。

这很有趣，因为默认颜色似乎不是深灰色或黑色。黑色本质上与透明相同，因为主视图背景是黑色的。深灰色比默认值更浅。

class TableInterfaceController: WKInterfaceController {

@IBOutlet var tableOutlet: WKInterfaceTable!

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

    let arrayOfObjects = ["ORANGE","PURPLE","BLUE","GRAY","YELLOW"]

    tableOutlet.setNumberOfRows(arrayOfObjects.count, withRowType: "row")

    for (var i = 0; i < arrayOfObjects.count; i++) {

        let row = tableOutlet.rowControllerAtIndex(i) as? RowController
        let labelValue = arrayOfObjects[i]

        row?.labelOutlet.setText(labelValue)   
    } 
}

override func table(table: WKInterfaceTable, didSelectRowAtIndex rowIndex: Int) {

    let row = tableOutlet.rowControllerAtIndex(rowIndex) as? RowController

    row?.groupOutlet.setBackgroundColor(UIColor.purpleColor())

    if (row!.isSelected) {
        row!.isSelected = false
        row?.groupOutlet.setBackgroundColor(UIColor.blackColor())

    }
    else {
        row?.isSelected = true
        row?.groupOutlet.setBackgroundColor(UIColor.purpleColor())
    }
}


class RowController: NSObject {
@IBOutlet var labelOutlet: WKInterfaceLabel!
@IBOutlet var groupOutlet: WKInterfaceGroup!
var isSelected : Bool = false

}

我想要这样

您需要实现以下更改。

let arrayOfObjects = [["text":"ORANGE", "color":UIColor.orangeColor(),"status":false] as NSMutableDictionary ,["text":"PURPLE", "color":UIColor.purpleColor(),"status":false] as NSMutableDictionary,["text":"BLUE", "color":UIColor.blueColor(),"status":false] as NSMutableDictionary,["text":"GRAY", "color":UIColor.grayColor(),"status":false] as NSMutableDictionary,["text":"YELLOW", "color":UIColor.yellowColor(),"status":false] as NSMutableDictionary];

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

    tableOutlet.setNumberOfRows(arrayOfObjects.count, withRowType: "row")

    for (var i = 0; i < arrayOfObjects.count; i++) {

        let row = tableOutlet.rowControllerAtIndex(i) as? RowController
        row?.updateData(arrayOfObjects[i] as NSMutableDictionary);
    }

}

override func table(table: WKInterfaceTable, didSelectRowAtIndex rowIndex: Int) {

    let selectedRow = tableOutlet.rowControllerAtIndex(rowIndex) as? RowController

    for (var i = 0; i < arrayOfObjects.count; i++) {

        let row = tableOutlet.rowControllerAtIndex(i) as? RowController

        //-- 
        let data = arrayOfObjects[i] as NSMutableDictionary
        data["status"] = (row == selectedRow);

        row?.updateData(arrayOfObjects[i] as NSMutableDictionary);
    }
}


class RowController: NSObject {

@IBOutlet var labelOutlet: WKInterfaceLabel!
@IBOutlet var groupOutlet: WKInterfaceGroup!

   func updateData(data:NSMutableDictionary){

    let labelValue = data["text"] as! String
    let color = data["color"] as! UIColor
    let status = data["status"] as! Bool

    //--
    self.labelOutlet.setText(labelValue)
    self.groupOutlet.setBackgroundColor(status ? color :  UIColor.blackColor());

   }//F.E
}
