在Swift中設置計時器

Question

我無法獲得計時器在Swift中工作請幫助。我收到錯誤extra 'selector' in call。

var timer = NSTimer.scheduledTimerWithTimeInterval(
    1, 
    target: self, 
    selector: Selector ("result"), 
    userInfo: nil, 
    repeats: true 
) 

Answer 1

一個從一個方法我說：

override func viewDidLoad() { 
      super.viewDidLoad() 

      let aSelector : Selector = "updateTime" 
      let timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: aSelector, userInfo: nil, repeats: true) 

     } 

     func updateTime() { 

     } 

Answer 2

使用這個代替

var timer = NSTimer.scheduledTimerWithTimeInterval (
    1, 
    target: self, 
    selector: "result", 
    userInfo: nil, 
    repeats: true 
)
