override func viewDidLoad() {
super.viewDidLoad()
fadeBackground()
NSTimer.scheduledTimerWithTimeInterval(self.fadeTime, target: self, selector: Selector("fadeBackground"), userInfo: nil, repeats: true)
}
func fadeBackground(){
var spiralView: UIImageView?
var subviews = self.view.subviews
for v in subviews{
if v.isKindOfClass(UIImageView){
spiralView = v as? UIImageView
}
}
UIView.animateWithDuration(self.fadeTime, delay: 0, options: UIViewAnimationOptions.AllowUserInteraction, animations: { [unowned self] () -> Void in
var randomIndex = Int(arc4random_uniform(UInt32(CONSTANTS.MainColorScheme.count)))
var randomIndex2 = Int(arc4random_uniform(UInt32(CONSTANTS.MainColorScheme.count)))
self.view.backgroundColor = CONSTANTS.MainColorScheme[randomIndex]
if spiralView != nil {
spiralView!.tintColor = CONSTANTS.MainColorScheme[randomIndex2]
}
}) { (stuff Bool) -> Void in
}
}
如您所见,我已经在封闭中添加了
[unowned self]
。我不确定为什么这个视图控制器仍然不调用deinit()。我猜那里仍然有内存泄漏?我需要在viewDidDisappear上停止计时器吗?我怎么做?
最佳答案
解决了我的问题。
我必须使viewWillDisappear上的计时器无效。
var fader: NSTimer?
override func viewWillDisappear(animated: Bool) {
println("lobby viewWillDisappear")
super.viewWillDisappear(animated)
self.fader!.invalidate()
self.fader = nil
}
关于ios - 由于封闭强引用或NSTimer,我的Swift代码未调用deinit。我该如何解决?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/29889764/
