Error getting artwork for current song

Grabbing album art for current song and using it to change a certain imageView.image generates an error, but no longer crashes. (It did before because I left out the if (!artwork) error handling. Eheh.)

This method:

- (void)handleNowPlayingItemChanged:(id)notification {
    MPMediaItem *item = self.musicPlayer.nowPlayingItem;
    CGSize albumCoverSize = self.albumCover.bounds.size;
    MPMediaItemArtwork *artwork =
                            [item valueForProperty:MPMediaItemPropertyArtwork];
    if (artwork) {
        self.albumCover.image = [artwork imageWithSize:albumCoverSize];
    } else {
        self.albumCover.image = nil;
    }
}

Explodes like this:

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
CPSqliteStatementReset: 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

But only on launch. And it still shows the image (or lack thereof). Weird.

Edit: The iPod Library is readonly (apps can't change anything, only iTunes), so maybe it's yelling at

me for writing a readonly something, but still al开发者_如何学Pythonlowing it because nothing readonly is being modified?

And after that's fixed, I need to get resizing working (for Landscape support) instead of IB's stretching.

Not vital, but still a nice thing to have.

Here's what I do. It creates no errors, and produces an image every time. If the song doesn't have an image, it defaults to the one I provide. I think because you're not checking for an image with a specific size (320 by 320, matching the screen width for me), it fails to figure it out correctly. I don't know why you're getting the SQLite error, but hopefully this fixes it!

MPMediaItemArtwork *artworkItem = [self.musicPlayer.nowPlayingItem valueForProperty: MPMediaItemPropertyArtwork];
if ([artworkItem imageWithSize:CGSizeMake(320, 320)]) {
    [self.currentlyPlayingArtworkView setImage:[artworkItem imageWithSize:CGSizeMake (320, 320)]];
}
else {
    [self.currentlyPlayingArtworkView setImage:[UIImage imageNamed:@"NoArtworkImage"]];
}

Putting this here so the question can be marked as Answered.
