免责声明：我的回答完全来自挖掘文件本身。

.app 是应用程序包。它们包含可执行文件， Info.plist 文件，图标，启动图像和一些其他应用程序资源。只有应用程序捆绑包才真正安装到设备上。

.apps are application bundles. They contain the executable file, an Info.plist file, an icon, a launch image, and some other application resources. Application bundles are the only ones that actually get installed onto your device.

.ipa s是的存档>包含 .app 捆绑包以及其他一些仅供iTunes使用的文件，例如 iTunesArtwork 。它们是iTunes管理应用程序的方式，据我所知，除了App Store信息之外，它们与应用程序本身没有任何关系。

.ipas are archives that contain .app bundles as well as some other files meant only for iTunes to use, for instance iTunesArtwork. They are how iTunes manages applications, and as far as I can tell have little to do with the applications themselves other than App Store information.

我没有使用Flash CS5的导出到iPhone功能，但是您只需将 .ipa 文件拖到iTunes上，它将显示在应用程序列表中。

I haven't worked with Flash CS5's export to iPhone feature, but you should be able to just drag your .ipa file to iTunes and it'll appear in the Apps list.

还有可能在Adobe Flash Professional CS5中开发iphone应用程序吗？

And also is it possible to develop iphone application in Adobe flash professional cs5?

从某种意义上说，您的iPhone软件可能不会永久崩溃，但正如phwd和David所说，您的应用不会进入App Store。

It is possible in the sense that your iPhone software won't crash permanently or something, but as phwd and David have said, your app will not make it to the App Store.
