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