Question

我不能得到一个计时器工作在斯威夫特请帮助。我得到错误extract'selector'in call。

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

Answer 1

一个来自我写的方法：

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

改用这个

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