如果你有一个变量，它是一个影片剪辑，雪碧，字符串，数字，INT，UINT，或者逻辑，你删除它的参考加入：

  myVariable的= NULL;
 

或

 删除（myVariable的）;
 

解决方案

将其设置为null是足以去除引用它包含的对象。

注意的语法删除运算符是删除object.member ，其中删除成员从一个键对象，因此将删除的引用，不管它包含的内容。

注意，GC只能出现一次的所有的引用给定对象都被删除。

If you have a variable that is a MovieClip, Sprite, String, Number, int, uint, or a Boolean, do you remove it's reference by adding:

myVariable = null;

OR

delete(myVariable);

setting it to null is sufficient to remove a reference to the object it contained.

Note that the syntax of the delete operator is delete object.member, which removes member as a key from object, and as such will remove a reference to whatever it contains.

note that GC can only occur once all references to a given object are removed.
