发挥iOS的一个短声 [英] Play a short sound in iOS

问题描述

我想我可以使用 AVAudioPlayer 播放声音，但是，我需要的是只打一短声，我不需要任何循环或细细粒度控制音量等。

I guess I could use AVAudioPlayer to play a sound, however, what I need is to just play a short sound and I don't need any loops or fine-grained control over the volume etc.

有没有一种简单的方法来做到这一点？

Is there an easy way to do this?

推荐答案

其他答案的每一个人......奇怪的是，（除非ARC为的有一个的答案启用）泄漏内存原来答案标记为正确的有没有明显的理由 retainCount 的电话。

Every single one of the other answers leaks memory (unless ARC is enabled for one of the answers)... oddly, the answer originally marked as correct has a call to retainCount for no apparent reason.

如果您分配/初始化的东西，它需要被释放（除非您使用ARC）。

If you alloc/init something, it needs to be released (unless you are using ARC).

如果你调用 AudioServicesCreateSystemSoundID（）你必须处理所产生的声音。

If you call AudioServicesCreateSystemSoundID() you have to dispose of the resulting sound.

查看<一个href=\"http://developer.apple.com/library/ios/#sample$c$c/SysSound/Introduction/Intro.html#//apple_ref/doc/uid/DTS40008018\">Audio UI听起来例子。

基本上是：

@interface MyClass:UI*ViewController // fixed
{
     SystemSoundID mySound;
}
@implementation MyClass
- (void) viewDidLoad {
    [super viewDidLoad];
    AudioServicesCreateSystemSoundID(.... URL ...., &mySound);
}

- (void) playMySoundLikeRightNowReally {
    AudioServicesPlaySystemSound(mySound);
}

- (void) dealloc {
   AudioServicesDisposeSystemSoundID(mySound);
   [super dealloc]; // only in manual retain/release, delete for ARC
}
@end
