Question

我有3个NSTimers：

var timer = NSTimer()
var scoreTimer = NSTimer()
var gameTmer = NSTimer()

然后在“viewDidLoad”中：

var sel = Selector("testFunc:")

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

scoreTimer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: sel, userInfo: nil, repeats: true)

gameTmer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: sel, userInfo: nil, repeats: true)

testFunc就是这样：

func testFunc(timer : NSTimer){
    println("working")
}

但他们不起作用。如果我尝试使用“fire（）”，那么他们会调用testFunc，但其他方式 - 不。

我找到了解决方案：

您可以删除.scheduledTimerWithTimeInterval并为每个计时器添加NSRunLoop.mainRunLoop().addTimer(timer, forMode: NSRunLoopCommonModes)。所以，你的代码看起来像这样：

var sel = Selector("testFunc:")

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

scoreTimer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: sel, userInfo: nil, repeats: true)

gameTmer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: sel, userInfo: nil, repeats: true)

NSRunLoop.mainRunLoop().addTimer(timer, forMode: NSRunLoopCommonModes)

NSRunLoop.mainRunLoop().addTimer(scoreTimer, forMode: NSRunLoopCommonModes)

NSRunLoop.mainRunLoop().addTimer(gameTmer, forMode: NSRunLoopCommonModes)

NSTimers迅速不开火
