iOS音频播放(系统音效播放)

昨天遇到了系统提示音的播放(类似于系统短音提示音，按键提示音)，最终发现其实系统声音的播放其实很简单，在这里做一个纪录
这里的声音播放使用AVFoundation框架

播放系统音效(系统提示音效)

//其中的soundID是系统音效ID可以在下面地址找到
//soundID的类型是SystemSoundID其实就是UInt32需要强转一下eg:(UInt32)1007
AudioServicesPlaySystemSound(soundID);

系统音效ID查看：http://iphonedevwiki.net/index.php/AudioServices

播放网络缓存到沙盒document下的音频文件

//name是音频文件的名称
NSString *documents = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *urlString = [documents stringByAppendingPathComponent:name];

SystemSoundID soundID = 0;

if (!soundIDs)
{
    soundIDs = [NSMutableDictionary dictionary];
}
else
{
    soundID = (SystemSoundID)[soundIDs[soundIDName] integerValue];
}

if (soundID == 0)
{
    NSURL *url = [NSURL URLWithString:urlString];
    AudioServicesCreateSystemSoundID((__bridge CFURLRef _Nonnull)url, &soundID);
    soundIDs[soundIDName] = [NSString stringWithFormat:@"%zd",soundID];
}
AudioServicesPlaySystemSound(soundID);

播放网络app的boundle中的音频文件

//name是音频文件的名称
NSString *urlString = [NSString stringWithFormat:@"%@",[[NSBundle mainBundle] pathForResource:name ofType:nil]];

SystemSoundID soundID = 0;

if (!soundIDs)
{
    soundIDs = [NSMutableDictionary dictionary];
}
else
{
    soundID = (SystemSoundID)[soundIDs[soundIDName] integerValue];
}

if (soundID == 0)
{
    NSURL *url = [NSURL URLWithString:urlString];
    AudioServicesCreateSystemSoundID((__bridge CFURLRef _Nonnull)url, &soundID);
    soundIDs[soundIDName] = [NSString stringWithFormat:@"%zd",soundID];
}
AudioServicesPlaySystemSound(soundID);

为了方便使用将音频播放做了下简单封装成JLBAudioTool使用简单，有兴趣可以看一下https://github.com/tiancanfei/JLBAudioTool
