斯威夫特：如何设置了优雅与他人（又名POD）混合音频会议 [英] Swift: how to set up an audio session that gracefully mixes with others (aka Pod)

问题描述

这code片段时，其他音频（又名iPod的）停止：

This code snippet makes the other audio (aka iPod) to stop:

func setSessionPlayer() {

    var audioSessionError: NSError?
    let audioSession = AVAudioSession.sharedInstance()

    audioSession.setActive(true, error: nil)

    if audioSession.setCategory(AVAudioSessionCategoryPlayback, withOptions:AVAudioSessionCategoryOptions.MixWithOthers,
        error: &audioSessionError) {
            println("Successfully set the audio session")
    } else {
        println("Could not set the audio session")
    }

}

我是什么失踪？

推荐答案

我想这是因为你设置 audioSession.active 之前，它的配置为 MixWithOthers 。移动 audioSession.setActive 下面的if块，像这样：

I think it's because you're setting the audioSession.active before it's configured to MixWithOthers. Move audioSession.setActive below the if block like so:

if audioSession.setCategory(AVAudioSessionCategoryPlayback, withOptions:AVAudioSessionCategoryOptions.MixWithOthers,
    error: &audioSessionError) {
        println("Successfully set the audio session")
} else {
    println("Could not set the audio session")
}

audioSession.setActive(true, error: nil)
