Manually Edit NSUserDefaults

[red]

Is it possible to view the values stored in NSUserDefaults standardUserDefaults without running the simulator? it would be nice to edit/clear/view them for debugging purposes.

I may have found a bug in the simulator. NSUserDefaults cannot remove a key from memory permanently. I have this code:

- (void)applicationDidFinishLaunching:(UIApplication *)application {
[[NSUserDefaults standardUserDefaults] removeObjectForKey:KEY_IDENTIFIER];
...
}
// Function that gets called later in the code
NSMutableArray *temp = [[NSUserDefaults standardUserDefaults] objectForKey:KEY_IDENTIFIER];
NSLog(@"  Delegate: Array = %@", temp);

When I run this code, it will display temp = nil (as expected). Then, I close the simulator and uncomment the line of code that removes the object from NSUserDefaults and I build the code again. The value of temp is not nil. It equals the values that were stored in [[NSUserDefaults standardUserDefaults] removeObjectForKey:KEY_IDENTIFIER] from a previous time.

Is this a bug, or am i missing something huge?

Try resetting all contents and settings in the simulator and see what happens

<username> -> Library -> Application Support -> iPhone Simulator -> User -> Applications -> <figure out which folder is for app you're interested in, if more than one> -> Library -> Preferences -> com.yourname.yourappname.plist

I have the Applications folder stored as a Favorite so I can quickly get back to it. I don't know if the goofy alpha-numeric folder names stay the same for each app build, especially if you remove them, so I'm not sure how reliable a link to the specific folder would be. I'll set the view to be date-sorted, and the first item should be my most recently built app.


The problem you might be seeing is that you cannot pull -mutable- data (see docs) out of a plist. Trying reading it into an NSArray instead, see if that helps.
