没有为WKInterfaceTable调用didSelectRowAtIndex

Question

我在故事板中创建了一个推送segue从一个 WKInterfaceTableCell到另一个WKInterfaceController(称为DetailInterfaceController).

当我点击该行时, didSelectRowAtIndex未被调用.

有人知道我哪里错了,我怎么能传递字符串？

TableInterfaceController

didSelectRowAtIndexPath print 语句未被调用

@IBOutlet var table: WKInterfaceTable!
var objectsArray = ["1","2","3"]
var object: String!

override func table(table: WKInterfaceTable, didSelectRowAtIndex rowIndex: Int) {
    self.object = self.objectsArray[rowIndex]

    print(" object title: \(self.object)")
}


override func contextForSegueWithIdentifier(segueIdentifier: String) -> AnyObject? {
    // You may want to set the context's identifier in Interface Builder and check it here to make sure you're returning data at the proper times

    // Return data to be accessed in ResultsController
    return self.object
}

DetailsInterfaceController

标签未设置

@IBOutlet var label: WKInterfaceLabel!

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

    // Make sure data was passed properly and update the label accordingly
    if let val: String = context as? String {
        self.label.setText(val)
    } else {
        self.label.setText("")
    }
    // Configure interface objects here.
}

为什么不叫:

table:didSelectRowAtIndex:由于您使用了故事板segue,因此不被调用是正常的.从WKInterfaceController文档:

如果将操作方法​​连接到storyboard文件中的表,则WatchKit不会调用此方法.

如何传递选定的行数据:

您应该使用contextForSegueWithIdentifier:inTable:rowIndex:返回所选行的上下文:

override func contextForSegueWithIdentifier(segueIdentifier: String, inTable table: WKInterfaceTable, rowIndex: Int) -> AnyObject? {
    if segueIdentifier == "someSegueIdentifier" {
        return objectsArray[rowIndex]
    }
    return nil
}
