我在故事板中创建了一个push segue,从WKInterfaceTableCell到另一个WKInterfaceController(称为DetailInterfaceController).
当我点击该行时,未调用didSelectRowAtIndex.
有人知道我哪里错了,我怎么能传递字符串？
TableInterfaceController
不调用didSelectRowAtIndexPath打印语句
@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.
}
解决方法
为什么不叫：
表格是正常的：didSelectRowAtIndex：因为你使用了故事板segue而没有被调用.从WKInterfaceController文档：
If you connected an action method to the table in your storyboard file,WatchKit does not call this method.
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
}
