在我的应用程序中，我正在向 Apple Watch 发送数据(即“UILabels”和“UIImage”)。正在成功发送。现在在我的 watch 主视图中显示从 ios 应用程序发送的数据，我有一个按钮打开一个表格 View ，我在其中拍摄了 1 个 ImageView 和 4 个标签。现在我也希望在表格 View 中显示相同的数据，即每次我将数据从 ios 应用程序发送到 watch 应用程序时，应该显示我从 ios 应用程序发送的每个条目并且也应该保存。
我希望数据显示为与保存在我的 ios 应用程序中的数据相同，如下图所示
:

我 watch 的源代码
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void)
{
//print(message.values)
MessageData = NSMutableDictionary(object: message, forKey: "data")
print("\(MessageData)")
watch_ticket_category.setText("\(MessageData["data"]!["Watchdat"]!!["ticket_category"] as! String)")
watch_displayImage.setImage(UIImage(named: MessageData["data"]!["Watchdat"]!!["imagePath"] as! String))
watch_ticketType.setText("\(MessageData["data"]!["Watchdat"]!!["ticket_type"] as! String)")
watch_ticketTime.setText("\(MessageData["data"]!["Watchdat"]!!["time"] as! String)")
watch_ticketDate.setText("\(MessageData["data"]!["Watchdat"]!!["date"] as! String)")
}
最佳答案
您可能需要使用 updateApplicationContext(_:)，并将传输的数据存储在 iPhone 上，并始终通过 updateApplicationContext 共享，它始终会更新数据.
