ios - Swift- 将数据从多节 TableView 传递到 ViewController

Question

我有一个两部分的表格 View (见下图)

当我点击“A”行时，会出现另一个带有字母“A”的表格 View

当我点击“B”行时，会出现另一个带有字母“B”的表格 View

单击 C 行时如何将字母“C”传递给另一个表格 View ？

这是我在 TableView 中的代码:导入 UIKit

类 manhinh1:UITableViewController {

var UserDefault:NSUserDefaults!
var array:[[String]]!
override func viewDidLoad() {
    super.viewDidLoad()

    UserDefault = NSUserDefaults()
    array = [["A","B"],["C","D","E"]]

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Potentially incomplete method implementation.
    // Return the number of sections.
    return array.count
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete method implementation.
    // Return the number of rows in the section.
    if section == 0 {
    return array[0].count
    }
    if section == 1 {
    return array[1].count
    }
    return 1
}


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell

    if indexPath.section == 0 {
    cell.textLabel?.text = array[0][indexPath.row]
    }
    if indexPath.section == 1 {
    cell.textLabel?.text = array[1][indexPath.row]
    }
    // Configure the cell...

    return cell
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    var row = self.tableView.indexPathForSelectedRow()!.row

    UserDefault.setObject(array[0][row], forKey: "selected")
}

这是第二个 View 中的代码:导入 UIKit

类 View Controller :UIViewController {

var UserDefault:NSUserDefaults!
@IBOutlet weak var lbldata: UILabel!
override func viewDidLoad() {
    super.viewDidLoad()
    UserDefault = NSUserDefaults()
    // Do any additional setup after loading the view, typically from a     }
    lbldata.text = UserDefault.objectForKey("selected") as! String
}
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

我确实在 prepareForSegue 中尝试了一些代码，但没有成功。我希望你们能告诉我一个方法。谢谢

您必须获取行和部分才能访问您的多维数组。然后获取 segue 的目标 View Controller 并将数组中的相应值分配给 UserDefault 属性:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    var row = self.tableView.indexPathForSelectedRow()!.row
    var section = self.tableView.indexPathForSelectedRow()!.section

    var destinationViewController = segue.destinationViewController as! ViewController 

    destinationViewController.UserDefault.setObject(array[section][row], forKey: "selected")
}
