如何以编程方式在 iOS 中访问其他已安装应用的 info.plist？

Question

I want to check the versions of other installed apps on my iPad from within my app. I know this information is stored in their info.plist files.

How can I access the plist of other installed apps programmatically? My apps are not published on the app store, so private methods are acceptable.

Answer 1

You are right, these values are stored in the Info.plist - more specifically, under the CFBundleShortVersionString and (should you need this too), a build number under the CFBundleVersion key.

NSBundle has a method called infoDictionary which returns the bundle's Info.plist (your app's if initialized using mainBundle ), so in theory you should be able to load any application bundle this class.
