带有Swift的ID3标签

问题描述 投票:13回答:1

我正在寻找一种使用Swift修改ID3标签的方法。更具体地说,我想将专辑封面图像写入mp3 / m4a文件。

Swift库是最好的,但是我将尽一切可以在Swift中完成的工作。我不想依赖另一种语言的库。

我快速浏览了AVFoundation,但它似乎仅用于音频/视频播放和转换。这是关于我从ID3标签中找到的最接近的:https://developer.apple.com/library/mac/documentation/AVFoundation/Reference/AVAsset_Class/

有任何建议吗?

我一遍又一遍地面临着同样的问题,所以我决定为此建立一个快速的框架。您可以在这里找到它:https://github.com/philiphardy/ID3Edit

将其添加到您的Xcode项目中,然后通过进入项目设置>常规>嵌入式二进制文件,确保将其嵌入

这里是如何在您的代码中实现它:

import ID3Edit
...
do
{
   // Open the file
   let mp3File = try MP3File(path: "/Users/Example/Music/example.mp3")
   // Use MP3File(data: data) data being an NSData object
   // to load an MP3 file from memory
   // NOTE: If you use the MP3File(data: NSData?) initializer make
   //       sure to set the path before calling writeTag() or an
   //       exception will be thrown

   // Get song information
   print("Title:\t\(mp3File.getTitle())")
   print("Artist:\t\(mp3File.getArtist())")
   print("Album:\t\(mp3File.getAlbum())")
   print("Lyrics:\n\(mp3File.getLyrics())")

   let artwork = mp3File.getArtwork()

   // Write song information
   mp3File.setTitle("The new song title")
   mp3File.setArtist("The new artist")
   mp3File.setAlbum("The new album")
   mp3File.setLyrics("Yeah Yeah new lyrics")

   if let newArt = NSImage(contentsOfFile: "/Users/Example/Pictures/example.png")
   {
          mp3File.setArtwork(newArt, isPNG: true)
   }
   else
   {
          print("The artwork referenced does not exist.")
   }

   // Save the information to the mp3 file
   mp3File.writeTag() // or mp3.getMP3Data() returns the NSData
                      // of the mp3 file
}
catch ID3EditErrors.FileDoesNotExist
{
   print("The file does not exist.")
}
catch ID3EditErrors.NotAnMP3
{
   print("The file you attempted to open was not an mp3 file.")
}
catch {}
