iOS SQLite Errors in Xcode Console from Media Query

[Tyre]

I'm querying the iPod library on my iPhone and am coming running into console output in Xcode and the following error in the console of my iPhone (as seen in Organizer):

May 27 22:11:04 unknown sandboxd[2512] <Notice>: QueryTesting(2510) deny file-write-mode /private/var/mobile/Media/iTunes_Control/iTunes/iTunes Library.itlp/Library.itdb

What exactly does all this mean? Here is the specific method that I'm calling, passing in an MPMediaItem and returning a dictionary of its properties.

+(NSDictionary *) initWithMPMediaItem:(MPMediaItem *) song andSongNumber: (int)songCount{


//Create & initialize NSStrings for keys
//Create NSArray to hold keys

NSString *songKey = [NSString stringWithFormat: @"%i Song Title", songCount];
NSString *albumKey = [NSString stringWithFormat: @"%i Album", songCount];
NSString *artistKey = [NSString stringWithFormat: @"%i Artist", songCount];
NSString *artistIDKey = [NSString stringWithFormat: @"%i Artist Persistent ID", songCount];
NSString *lastPlayedKey = [NSString stringWithFormat: @"%i Late Played Date", songCount];
NSString *genreKey = [NSString stringWithFormat: @"%i Genre", songCount];
NSString *ratingKey = [NSString stringWithFormat: @"%i User Rating", songCount];
NSString *playCountKey = [NSString stringWithFormat: @"%i Play Count", songCount];

NSArray *propertyKeys = [[NSArray alloc] initWithObjects:songKey, albumKey, artistKey, artistIDKey, 
                        lastPlayedKey, genreKey, ratingKey, playCountKey, nil];

//Create & initialize NSStrings to hold song property information
//Create NSArray to hold the values

NSString *songTitle = [song valueForProperty:MPMediaItemPropertyTitle];
NSString *albumName = [song valueForProperty:MPMediaItemPropertyAlbumTitle];
NSString *artistName = [song valueForProperty:MPMediaItemPropertyArtist];
NSString *artistID = [song valueForProperty:MPMediaItemPropertyArtistPersistentID];
NSString *lastPlayed = [song valueForProperty:MPMediaItemPropertyLastPlayedDate];
NSString *genre = [song valueForProperty:MPMediaItemPropertyGenre];
NSString *userRating = [song valueForProperty:MPMediaItemPropertyRating];
NSString *playCount = [song valueForProperty:MPMediaItemPropertyPlayCount];

NSArray *propertyValues = [[NSArray alloc] initWithObjects:songTitle, albumName, artistName, artistID, 
                           lastPlayed, genre, userRating, playCount, nil];

//Create NSDictionary to store information, initializing it with
//above data, then returning the resulting dictionary

NSDictionary *songInfo = [[NSDictionary alloc] initWithObjects:propertyValues forKeys:propertyKeys];

return songInfo;
}

Why the error? It also doesn't return the information that I'm requesting, but produces no XCode errors or even warnings, and continues to run the program after that. It's as if it just skips some of these steps.

At first glance I don't see anything in there that would be causing this. This error may be coming from somewhere else in your code. What I do see is that you are shoving any kind of pointer into an NSString... For example the last played property is going to return an NSDate.
