When running my program to query the iPod library of my iPhone, I get the following output in the console:
CPSqliteStatementPerform: attempt to write a readonly database for UPDATE ddd.ext_container SET orig_date_modified = (SELECT date_modified FROM container WHERE pid=container_pid) WHERE orig_date_modified=0
I have disabled everything that outputs to the console so it isn't as if I am having an error with NSLog. What is going on here and how can I fix it. I'll include the overall class source code that I am calling, along with the class that does the work (sorry for posting it all:
+(NSMutableDictionary *) makeQuery {
MPMediaQuery *query = [[MPMediaQuery alloc] init]; //query iPod library
NSString *facebookIDKey = @"Facebook ID";
NSString *genericFacebookID = @"1234567890";
NSMutableDictionary *organizedSongData = [NSMutableDictionary dictionaryWithObject:genericFacebookID forKey:facebookIDKey];
NSArray *allSongs = [query collections];
//only add those songs which have not
//been played since last login
for (MPMediaItem *recent in allSongs) {
NSDate *lastPlayed = [recent valueForProperty:MPMediaItemPropertyLastPlayedDate];
int songCounter = 1;
BOOL uploadInfo = [[PlayedSinceLastLogin alloc] initWithLastPlayedDateOfSong:lastPlayed];
if (uploadInfo == YES) {
//adds songs into
[organizedSongData addEntriesFromDictionary: [MakeDicForSongInfo initWithMPMediaItem:recent andSongNumber:songCounter]];
songCounter++;
}
}
return organizedSongData;
}
Here is the actual brunt of the work, done in the MakeDicForSongInfo:
+(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;
}
Could it be something in accessing all that Media information that spooks the iPhone?
