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 {}
