swift - 使用 swift 自动刷新

Question

我知道如何使用拉动刷新以及如何制作刷新按钮。我只是想知道是否有人知道如何或可以将我链接到一个页面来教我如何自动刷新页面。比如每隔15秒自动刷新一次。

Answer 1

从这里开始:

@IBOutlet weak var yourButton: UIButton!
var timer: NSTimer!
var refresher: UIRefreshControl!


override func viewDidLoad() {
    super.viewDidLoad()
    yourButton.addTarget(self, action: "refresh:", forControlEvents: .TouchUpInside)
    refresher = UIRefreshControl()
    refresher.addTarget(self, action: "refresh:", forControlEvents: .ValueChanged)

    timer = NSTimer.scheduledTimerWithTimeInterval(15.0, target: self, selector:"refreshEvery15Secs", userInfo: nil, repeats: true)
}

func refreshEvery15Secs(){
    // refresh code
}

func refresh(sender: AnyObject){

     refreshEvery15Secs() // calls when ever button is pressed
}
