我正在尝试使用NSTimer的userinfo传递UIButton.我已经阅读了NSTimers上有关stackoverflow的每篇文章.我变得非常接近,但却无法到达那里.这篇文章有所帮助

Swift NSTimer将userInfo检索为CGPoint

func timeToRun(ButonToEnable:UIButton) {
    var  tempButton = ButonToEnable
    timer = NSTimer.scheduledTimerWithTimeInterval(4, target: self, selector: Selector("setRotateToFalse"), userInfo: ["theButton" :tempButton], repeats: false)    
}

计时器运行的功能

func setRotateToFalse() {
    println(  timer.userInfo )// just see whats happening

    rotate = false
    let userInfo = timer.userInfo as Dictionary<String, AnyObject>
    var tempbutton:UIButton = (userInfo["theButton"] as UIButton)
    tempbutton.enabled = true
    timer.invalidate()    
}
