Saving NSMutableDictionary to plist iOS - objective-c

Question

This has become very frustrating over the past day-and-a-bit-too-much: why doesn't this work?
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.plist",kAllScoresUnorderedArray]];
NSMutableDictionary *test = [[NSMutableDictionary alloc] init];
[test setObject:#"bob" forKey:#"tmo"];
[test writeToFile:path atomically: YES];
I have used it before, and it worked perfectly: is there something I am forgetting to add in my info.plist? That is the only thing I can think of.
Thank you for helping!
EDIT:
Maybe it has something to do with Xcode 4.5 and iOS6? It worked in 4.3/iOS5

Have you added the .plist file to your project? If so, try this:
NSError *error;
NSFileManager *fileManager = [[NSFileManager alloc] init];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.plist",kAllScoresUnorderedArray]];
if (![fileManager fileExistsAtPath: path])
{
NSString *bundle = [[NSBundle mainBundle] pathForResource:kAllScoresUnorderedArray ofType:#"plist"];
[fileManager copyItemAtPath:bundle toPath: path error:&error];
}
NSMutableDictionary *test = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
[test setObject:#"bob" forKey:#"tmo"];
[test writeToFile:path atomically: YES];
If not, create the property list in your project.
