Can I programmatically flip Info.plist values while my application is running?

Question

I am interested in using the SBUsesNetwork and UIRequiresPersistentWiFi keys in my application; however, I would like to enable them only when using a certain set of view controllers. Is there a way to programmatically flip those key values while the application is running?

Answer 1

You can't modify your bundle contents while running, you don't have write access to that directory. I'm not sure there's a way to do exactly what you want.

Answer 2

I know you can get your info.plist as an NSDictionary via NSBundle with the following:

NSDictionary* infoDictionary = [[NSBundle mainBundle] infoDictionary];

from there you could make a mutableCopy of the NSDictionary and set the values therein. When making queries to the keys you'll have to make sure to query the NSDictionary and not your info.plist file, but it shouldn't be hard to encapsulate all of this into a class that handles both problems for you.

As for modifying your app's info.plist file directly there could be issues there (e.g, if you modify the file the code signing will fail and your app will be considered corrupt), though I'm not certain on this.
