Question

我创建了一个应用程序，其中数据显示在上一个视图的当前视图中。数据包括图像和三个标签。现在在当前视图中我有一个＆＃34;发送到观看＆＃34;按钮，它还将数据存储到数据库，同时它将传输显示的数据进行观察。我正在使用FMDB数据库来存储数据。如何将数据从IOS应用程序传输到观看应用程序。任何人都可以一步一步解释我，因为我是IOS开发的新手。我目前对故事板的看法如下： my storyboard view

当我运行我的应用时，其当前页面位于下方 application running page

我的上一个视图的源代码如下：

class TicketDetailViewController: UIViewController, WCSessionDelegate {

var databasePath = NSString()
var holding_Image: UIImage?
var hold_ticketName: String = ""
var hold_ticketDate: String = ""
var hold_ticketTime: String = ""
var session: WCSession!


@IBOutlet weak var ticket_grey: UIImageView!
@IBOutlet weak var cropped_frame: UIImageView!
@IBOutlet weak var display_image: UIImageView!
@IBOutlet weak var ticket_type_name: UILabel!
@IBOutlet weak var ticket_date: UILabel!
@IBOutlet weak var ticket_time: UILabel!


override func viewDidLoad()
{
    super.viewDidLoad()

    if WCSession.isSupported(){
        self.session = WCSession.defaultSession()
        self.session.delegate = self
        self.session.activateSession()
    }

    display_image.image = holding_Image
    ticket_type_name.text = hold_ticketName
    ticket_date.text = hold_ticketDate
    ticket_time.text = hold_ticketTime

    let filemgr =  NSFileManager.defaultManager()
    let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
    let docsDir = dirPaths[0]
    var ticketDB: FMDatabase

    databasePath = (docsDir as NSString).stringByAppendingPathComponent("tickets.sqlite")

    if !filemgr.fileExistsAtPath(databasePath as String)
    {

        ticketDB = FMDatabase(path: databasePath as String)
        if ticketDB.open()
        {

            let sql_stmt = "CREATE TABLE IF NOT EXISTS TICKETS (ID INTEGER PRIMARY KEY AUTOINCREMENT, IMAGE TEXT, TICKET_TYPE TEXT, DATE TEXT, TIME TEXT)"
                    if !ticketDB.executeStatements(sql_stmt)
                    {
                        print("Error: \(ticketDB.lastErrorMessage())")
                    }
                    ticketDB.close()
                    } else
                    {

                     print("Error: \(ticketDB.lastErrorMessage())")
                    }
        }

}
  @IBAction func sendToWatch(sender: UIButton) {

    let ticketDB = FMDatabase(path: databasePath as String)
    if ticketDB.open()
    {

        let insertSQL = "INSERT INTO TICKETS (image, ticket_type, date, time) VALUES ('\(display_image.image!)','\(ticket_type_name.text!)', '\(ticket_date.text!)', '\(ticket_time.text!)')"

        let result = ticketDB.executeUpdate(insertSQL,withArgumentsInArray: nil)

        if !result
        {

            print("Error: \(ticketDB.lastErrorMessage())")

        } else
        {

            let alt = PMAlertController(title: "Success!", description: "Your data is saved to Database!", image: UIImage(named: ""), style: .Alert)

            alt.addAction(PMAlertAction(title: "OK!", style: .Default, action: { (ACTION) -> Void in



            }))

            self.presentViewController(alt, animated: true, completion: nil)
            print(databasePath)

        }
    }

} }

您可以使用应用程序组共享数据或提交该数据。转到目标，点击功能，您可以找到“应用程序组”，只需启用它并添加“group.com.development.xyzapp”之类的条目，您可以通过该条目从iOS应用程序共享数据，反之亦然。您可以通过以下代码保存iOS应用中的数据。

- (void)sendDataToWatch { NSUserDefaults *userDefaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.development.xyzapp"]; [userDefaults setObject:object forKey:@"itemone"]; [userDefaults setObject:object forKey:@"itemtwo"]; [userDefaults synchronize]; }

现在你可以看到这些数据。

希望这会有所帮助。
