as3 垃圾回收 [转]

1. 试用弱侦:addEventListener("事件",function ,false,0,true);
2. loader.unload(); ----------- (loader.content as Bitmap).BitmapData.dispose();
3. 所有变量用完设为null
4.调用类,强制回收.

package {
import flash.net.LocalConnection;
public class MyGC {
public static function GC() {
try {
var lc1:LocalConnection = new LocalConnection();
var lc2:LocalConnection = new LocalConnection();
lc1.connect('name');
lc2.connect('name2');
} catch (e:Error) {
}
}
}
}
