AVAudioPlayer重置当前播放声音，并从一开始就玩 [英] AVAudioPlayer resetting currently playing sound and playing it from beginning

问题描述

我使用AVAudioPlayer，我想重置一个球员，如果它当前正在播放，并让它再次发挥有一个问题。

我尝试没有运气以下内容：

声音播放一次但第二次我选择它停止声音按钮，第三次再次启动的声音响了起来。

  //停止播放器并重新启动
如果（player.playing）{
    的NSLog（@复位声：％@，selectedSound）;
    [播放器停止]
    [播放器播放];
}其他{
    的NSLog（@playSound：％@，selectedSound）;
    [播放器播放];
}
 

我使用player.currentTime = 0，这表明将播放器复位，没有工作，我也尝试重置currentTime的= 0，然后调用播放，没有工作也尝试过。

  //停止播放器并重新启动
如果（player.playing）{
    的NSLog（@复位声：％@，selectedSound）;
    player.currentTime = 0;
    [播放器播放];
}其他{
    的NSLog（@playSound：％@，selectedSound）;
    [播放器播放];
}
 

解决方案

有关你的情况我想尝试以下

  //暂停播放器并重新启动
如果（player.playing）{
    的NSLog（@复位声：％@，selectedSound）;
    [播放暂停]
}player.currentTime = 0;
[播放器播放];
 

如果你要立即再次播放声音，我会建议暂停而不是停止。呼吁停止停止播放，并撤消需要播放的设置。

I'm having an issue using AVAudioPlayer where I want to reset a player if it's currently playing and have it play again.

I try the following with no luck:

The sound plays once but then the second time i select the button it stops the sound, the third time starts the sound up again.

//Stop the player and restart it
if (player.playing) {
    NSLog(@"Reset sound: %@", selectedSound);
    [player stop];
    [player play];
} else {
    NSLog(@"playSound: %@", selectedSound);
    [player play];      
}

I've also tried using player.currentTime = 0 which indicates that would reset the player, that didn't work, I also tried resetting currentTime = 0 and then calling play that didn't work.

//Stop the player and restart it
if (player.playing) {
    NSLog(@"Reset sound: %@", selectedSound);
    player.currentTime = 0;
    [player play];
} else {
    NSLog(@"playSound: %@", selectedSound);
    [player play];      
}

解决方案

For your situation I would try the following

//Pause the player and restart it
if (player.playing) {
    NSLog(@"Reset sound: %@", selectedSound);
    [player pause];
}

player.currentTime = 0;
[player play];

If you are going to immediately play the sound again, I would suggest pause instead of stop. Calling stop "Stops playback and undoes the setup needed for playback."
