免责声明:我的回答完全来自于文件本身的挖掘.

.apps 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.应用程序包是唯一真正安装到您设备上的应用程序包.

.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 是包含 .app 捆绑包以及其他一些仅供 iTunes 使用的文件的档案，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，与应用程序本身几乎没有关系.

.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，但是您应该可以将 .ipa 文件拖到 iTunes 中，它就会出现在应用列表中.

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.

也可以在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或其他原因，但正如 phwd 和 David 所说，您的应用将无法进入 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.
