如何在Swift中填充表格视图？

Question

I have written this code:

//Basic methods
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    self.DevicesTableView.registerClass(UITableViewCell.self,forCellReuseIdentifier: "cell")
    self.DevicesTableView.dataSource = self

}


var array = ["one","two"]

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
    return array.count
}

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

    cell.textLabel!.text = self.array[indexPath.row]

    return cell
}

So the code works pretty well and shows me the tableview filled with:

Row1 "One" Row2 "Two"

But how can I fill the TableView not at the beginning of my program but anytime else? I tried to call the methods below in an other function that viewDidLoad but it doest't work... why?

self.DevicesTableView.registerClass(UITableViewCell.self,forCellReuseIdentifier: "cell") self.DevicesTableView.dataSource = self

EDIT:

I would like to display an array which isn't initialized at the beginning of my program. It contains some BLE devices after the user searched for them.

表视图具有一个reloadData方法，该方法可以执行您想要的操作。

Its very simple

1. Update your data in your array
2. Then reload your tableview by using your_tableview.reloadData()

Ex:

var array = ["one","two","Three","Four"] // your array will take no.of.row in section
DevicesTableView.reloadData()
