昨天遇到了系統(tǒng)提示音的播放(類似于系統(tǒng)短音提示音，按鍵提示音)，最終發(fā)現(xiàn)其實(shí)系統(tǒng)聲音的播放其實(shí)很簡單钝侠，在這里做一個(gè)紀(jì)錄
這里的聲音播放使用AVFoundation框架
播放系統(tǒng)音效(系統(tǒng)提示音效)
//其中的soundID是系統(tǒng)音效ID可以在下面地址找到
//soundID的類型是SystemSoundID其實(shí)就是UInt32需要強(qiáng)轉(zhuǎn)一下eg:(UInt32)1007
AudioServicesPlaySystemSound(soundID);
系統(tǒng)音效ID查看：http://iphonedevwiki.net/index.php/AudioServices
播放網(wǎng)絡(luò)緩存到沙盒document下的音頻文件
//name是音頻文件的名稱
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);
播放網(wǎng)絡(luò)app的boundle中的音頻文件
//name是音頻文件的名稱
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);
為了方便使用將音頻播放做了下簡單封裝成JLBAudioTool使用簡單疤坝，有興趣可以看一下https://github.com/tiancanfei/JLBAudioTool
