NSTimer取消了我的UIView.animateWithDuration

Question

Every time NSTimer is called my animation is canceled

override func viewDidLoad() {
    super.viewDidLoad()

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

    self.mover()
}

/**
 Selector

 - parameter timer: NStimer
 */
func timer(timer:NSTimer!){
    self.lblTiempo.text = "Te haz movido"
}

How can I prevent NSTimer cancel my animations?

/**
 Mueve la imagen en la pantalla
 */
func mover(){


    let x = Int(arc4random_uniform(UInt32( 400 )))
    let y = Int(arc4random_uniform(UInt32( 400 )))

    UIView.animateWithDuration(self.juego!.velocidad,
        delay: 0.0,
        options: [.CurveEaseInOut, .AllowUserInteraction],
        animations: {
            self.imgBicho.center = CGPoint(x: x, y: y)
        },
        completion: { finished in
            self.mover()
    })
}

I am relatively new to the development of IOS, someone can help me with this, thanks.

Sure paulvs , Sorry it is a misspelling. The problem is with the NSTimer :(

Answer 1

I think the code you posted will crash straight away with an exception like this

'NSInvalidArgumentException', reason: '-[TestTimer.ViewController timer]: unrecognized selector sent to instance 0x7fb501c3faa0'

because the timer function has one argument

func timer(timer:NSTimer!){

while your NSTimer initialisation code passes a selector with no arguments

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

To fix this, change this line to

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

notice the colon : near the end.
