如何使用MPNowPlayingInfoCenter滑块调整音量变化

import MediaPlayer

// 设置音频会话
do {
    try AVAudioSession.sharedInstance().setCategory(.playback)
} catch {
    print("Failed to set audio session category: \(error)")
}

// 创建MPNowPlayingInfoCenter实例
let nowPlayingInfoCenter = MPNowPlayingInfoCenter.default()

// 设置音频信息
nowPlayingInfoCenter.nowPlayingInfo = [
    MPMediaItemPropertyTitle: "音频标题",
    MPMediaItemPropertyArtist: "艺术家",
    // 其他音频信息...
]

// 设置音量变化回调
nowPlayingInfoCenter.addTarget(self, action: #selector(volumeSliderValueChanged), for: .volumeSliderValueChanged)

@objc func volumeSliderValueChanged() {
    // 处理音量变化
    let volume = nowPlayingInfoCenter.volumeSlider.value
    // 其他处理...
}
