ios - 如何管理UIButton单击声音iOS

Question

我正在使用以下代码在按钮单击时发出声音，并且效果很好。问题是，如果我减小手机的音量，声音不会降低。我想按照音量按钮管理按钮的点击声音。我没有使用输入 View 。

SystemSoundID soundID;
NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"sound1" ofType:@"mp3"];
NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];
AudioServicesCreateSystemSoundID ((CFURLRef) CFBridgingRetain(soundUrl) , &soundID);
AudioServicesPlaySystemSound(soundID);

Answer 1

如Duncan C所建议，请尝试AVAudioPlayer:

导入AVFoundation.framework。

将代码段替换为:

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"sound1" ofType:@"mp3"];
NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
[player play];
