开始不清楚， 一直尝试想load图片一样加载一个swftools转换的swf，然后在尝试转换成movieclip的时候，总是报错， avmiMovieClip 不能转换成movieclip之类的。
但为什么有的swf可以轻松转换成movieclip呢？
后面我明白这两种movieclip根本就是不同存储格式了，—— 虽然都是swf后缀
关于movieclip ，我一直不太明白，其实它相当的有用。

无论如何， 下面的loadComplete就是没有执行，像是某个地方卡住了一样，但是、、、 我看了progess都是100%的。。 试过很多方式，还是一样结果。
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete)
但为什么其他方式就行了呢？ 几乎是一样的写法啊？
