我一直试图弄清楚如何使用脚本桥获取当前播放歌曲的iTunes艺术作品.我已经达到了适用于某些歌曲的程度,但对于其他人来说,我得到了一个SIGABRT.我不确定问题是什么,所以任何帮助都将不胜感激.这是我到目前为止:

iTunesApplication * iTunes = [SBApplication applicationWithBundleIdentifier:@"com.apple.iTunes"];
NSImage *songArtwork;
iTunesTrack *current = [iTunes currentTrack];
iTunesArtwork *artwork = (iTunesArtwork *)[[[current artworks] get] lastObject];
if(artwork != nil)
  songArtwork = [artwork data];
else
  songArtwork = [NSImage imageNamed:@"Image.tiff"];

NSMenuItem *artworkMenuItem = [[NSMenuItem alloc] initWithTitle:@"" action:NULL keyEquivalent:@""];
[songArtwork setSize:NSMakeSize(128, 128)];
[artworkMenuItem setImage:songArtwork];
[Menu insertItem:artworkMenuItem atIndex:0];

我可以使用一些歌曲,并在菜单项中很好地显示艺术作品,但对于其他人我在线上获得了一个SIGABRT:

[songArtwork setSize:NSMakeSize(128, 128)];

控制台的输出如下:
