Audio systemsound

播放震动效果  
播放系统音乐效果  
播放提示音效果

震动效果：  
NSString \*device = \[UIDevice currentDevice\]model\];  
if (device isEqualToString:@”iPhone”)\{  
AudioServicesPlaySystemSound(kSystemSoundID\_vibrate);  
\}else\{  
提示  
\}

提示音：  
//播放系统声音  
\- (void)playSystemSound\{  
NSString \*filePath = \[\[NSBundle mainBundle\] pathForResource:@”music” ofType:@”car”\];  
if (!filePath) \{  
return;  
\}  
NSURL \*url = \[NSURL fileURLWithPath:filePath\];  
//  
SystemSoundID system\_id;  
//绑定ID 和 URL  
AudioServicesCreateSystemSoundID((\_\_bridge CFURLRef) url, &system\_id);

//注册回调
    AudioServicesAddSystemSoundCompletion(system_id, NULL, NULL, AudioServicesSystemSoundFinish, NULL);
    //播放
    AudioServicesPlaySystemSound(system_id);

@end

void  
AudioServicesSystemSoundFinish( SystemSoundID ssID,  
void\* \_\_nullable clientData)\{  
AudioServicesRemoveSystemSoundCompletion(ssID);  
AudioServicesDisposeSystemSoundID(ssID);//手机静音的时候无效

播放提示音  
NSString \*filePath = \[\[NSBundle mainBundle\] pathForResource:@”music” ofType:@”car”\];  
if (!filePath) \{  
return;  
\}  
NSURL \*url = \[NSURL fileURLWithPath:filePath\];  
//

//注册回调
    AudioServicesAddSystemSoundCompletion(system_id, NULL, NULL, AudioServicesSystemSoundFinish, NULL);
    //播放
    AudioServicesPlaySystemSound(system_id);
    
    AudioServicesPlayAlertSound(system_id);//手机静音 播放声音 并震动
