Egret销毁问题(内存泄漏)

 

一 数组引用

移除场景时，值引用数组自动销毁

class HomeScene extends eui.Component{
	public arr:Array<Number> = [];	

	public constructor() {
		super();

		for(let i=0;i<10000;i++){
			this.arr.push(i);
		}
	}
}

　　

移除场景时，对象引用数组自动销毁，Ball对象自动销毁　

class HomeScene extends eui.Component{
	public arr:Array<Ball> = [];	

	public constructor() {
		super();

		for(let i=0;i<10;i++){
			let ball:Ball = new Ball();
			this.arr.push(ball);
			this.addChild(ball);
		}
	}
}

 

二 对象引用

移除场景时，引用对象Ball自动销毁

class HomeScene extends eui.Component{
	public ball:Ball;	

	public constructor() {
		super();

		this.ball = new Ball();
		this.addChild(this.ball);
	}
}

　　

 三 UI组件

移除场景时，UI组件自动销毁

class HomeScene extends eui.Component{
	public btn0:eui.Button;
	public btn1:eui.Button;
	public btn2:eui.Button;
	public btn3:eui.Button;
	public btn4:eui.Button;
	public btn5:eui.Button;
	public btn6:eui.Button;
	public btn7:eui.Button;
	public btn8:eui.Button;

	public constructor() {
		super();
		this.skinName = "HomeSceneSkin";
	}
}

　　

四  List

移除场景时，List会自动销毁

class HomeScene extends eui.Component{
	public list:eui.List;

	public constructor() {
		super();
		this.skinName = "HomeSceneSkin";

		this.list.itemRenderer = ListItem;
		this.list.dataProvider = new eui.ArrayCollection([1,2,3,4,5]);
	}
}

　　

 五  监听

移除场景时，监听会自动移除掉，HomeScene、List有监听，仍然会被销毁

印象中有监听不会被回收，但是测试来看，不停的反复增加和移除100个场景，内存并没有增加。

class HomeScene extends eui.Component{
	public list:eui.List;

	public constructor() {
		super();
		this.skinName = "HomeSceneSkin";

		this.list.itemRenderer = ListItem;
		this.list.dataProvider = new eui.ArrayCollection([1,2,3,4,5]);

		this.addEventListener(egret.TouchEvent.TOUCH_TAP, this.onTouchTap, this);
		this.addEventListener(egret.Event.REMOVED_FROM_STAGE, this.onRemove, this);
		this.list.addEventListener(egret.Event.CHANGE, this.onChange, this);
	}

	private onTouchTap(){
		
	}

	private onRemove(){
		 
	}

	private onChange(){

	}
}
