问题描述：AD杂志iPad版需要一个查看礼物的网站，有个效果是png带透明图片用jquery进行fade in和fade out。原本只需要在iPad上使用。结果客户说IE8运行的时候透明的不会呈现全黑。检查后发现Safari、Firefox、Chromx都正常浏览，唯独IE7、8会有问题。
问题分析：猜想是IE7、8对png的兼容问题。原因是：IE修改透明度，不是通过css属性，而是通过filter滤镜。在IE9，微软修复了此问题。但是此问题对于IE7、8是无解。
总结：IE实在是弱爆了。

AIR在Mac和PC平台下隐藏文件问题
问题描述：今天加班帮惠氏Wyeth启斌illuma抽奖AIR。在Mac下开发完去PC上测试，发现Mac上一切正常，而PC上程序无法顺利运行。
问题分析：把源代码转到PC运行，一步一步排查。发现PC上会加载隐藏文件，而Mac上不会加载隐藏文件。正是这些隐藏文件的加载导致不正常。
问题解决：
添加如下代码：
if(!file.isHidden)
一切OK了。
总结：Mac系统会忽略隐藏文件，与PC上会遍历所有文件不同。这也许是AIR的bug。

问题分析：开始以为是没有找到库，重新引用库，无效。后查Google，要删除掉Targets-Build Settings-Library Search Paths，照做，无效。最后找到以下这段：
|
It seems the library is built for phone deployment (ARM) but you are trying to link it to a simulator executable (x86). This won't work. Rebuild the library for the simulator.

问题解决：切换成Device编译，搞定。
