我用SpriteKit创建了一个简单的游戏,但每次运行游戏时,模拟器中的内存使用量增加约30mb,但游戏结束后永远不会减少.
当我运行游戏超过十次时,模拟器变得越来越慢并最终崩溃.
在这个简单的游戏中我有两个控制器和一个gamecene：
MainController通过触发按钮调用GameViewController
在GameViewController中,gamescene以这种方式初始化：
class GameViewController: UIViewController
{
var skView:SKView!
var scene:GameScene!
override func viewDidLoad() {
super.viewDidLoad()
scene = GameScene(size: view.bounds.size)
skView = view as SKView
skView.ignoresSiblingOrder = true
scene.scaleMode = .ResizeFill
scene.viewController = self
skView.presentScene(scene)
}
//with a prepareForSegue deinitialises the scene and skview:
override func prepareForSegue(segue: UIStoryboardSegue,sender: AnyObject?) {
if segue.identifier == "GameFinished"{
scene.removeAllActions()
scene.removeAllChildren()
scene.removeFromParent()
scene = nil
skView.presentScene(nil)
skView = nil
let target = segue.destinationViewController as MainController
}
}
}@H_301_10@
在GameScene中,viewController是一个属性
var viewController:GameViewController? = GameViewController()@H_301_10@
segue被触发：
self.viewController!.performSegueWithIdentifier("GameFinished",sender: nil)@H_301_10@
我也试过在GameScene中将remove方法放入deinit：
deinit{
self.removeAllActions()
self.removeAllChildren()
}@H_301_10@
仍然行不通
