Is there a way to see what's been saved to NSUserDefaults directly? I'd like to see if my data saved correctly.
You can find the pList file for your app in the simulator if you go to:
/users/your user name/Library/Application Support/iPhone Simulator/<Sim Version>/Applications
This directory has a bunch of GUID named directories. If you are working on a few apps there will be a few of them. So you need to find your app binary:
find . -name foo.app
./1BAB4C83-8E7E-4671-AC36-6043F8A9BFA7/foo.app
Then go to the Library/Preferences directory in the GUID directory. So:
cd 1BAB4C83-8E7E-4671-AC35-6043F8A9BFA7/Library/Preferences
You should find a file that looks like:
<Bundle Identifier>.foo.pList
Open this up in the pList editor and browse persisted values to your heart's content.
