iOS SDK Spotify - 백그라운드 플레이 없음

Question

백그라운드 재생으로 작동하는 Spotify iOS SDK를 가져올 수 없으므로 전화가 잠겨 있거나 응용 프로그램이 더 이상 작동하지 않을 때 트랙이 계속 재생됩니다.

내 Info.plist에 UIBackgroundModes는 이렇게 설정 한 :

<key>UIBackgroundModes</key> 
<array> 
    <string>audio</string> 
    <string>fetch</string> 
</array> 

는 내가 부족 뭔가 다른 또는 앱에 SDK를 설정할 때 내가 활성화해야 뭔가가 있나요? 어떤 도움

Answer 1

로 작성 2 단계

// MARK: Activate audio session 

func activateAudioSession() { 
    try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback) 
    try? AVAudioSession.sharedInstance().setActive(true) 
} 

// MARK: Deactivate audio session 

func deactivateAudioSession() { 
    try? AVAudioSession.sharedInstance().setActive(false) 
} 

Answer 2

에 미리

덕분에 나는 내 이전의 애플 리케이션 중 하나에 그것을 전에했던 생각합니다. 앱을 실행하자마자 오디오 세션을 구성해야한다고 생각하십시오.

다음은이를 수행하는 방법을 보여주는 코드입니다. 그러나이 AVAudioSession

1 단계

func audioStreaming(_ audioStreaming: SPTAudioStreamingController!, didChangePlaybackStatus isPlaying: Bool) { 
    if isPlaying { 
     self.activateAudioSession() 
    } else { 
     self.deactivateAudioSession() 
    } 
} 

에게 SPTAudioStreamingPlaybackDelegate를 구현하고 활성화하는 기능을 작성하고 비활성화 내 클래스를 확장하기 위해 내가 가진이 문제를 해결하려면 목적 C.
