導(dǎo)入頭文件

#import <AudioToolbox/AudioToolbox.h>

添加一個(gè)自己的音頻

• inFileURL ： 音頻文件路徑
• outSystemSoundID：該音頻標(biāo)記的ID，為后面播放此音頻時(shí)的查找

AudioServicesCreateSystemSoundID(   CFURLRef                    inFileURL,
                                    SystemSoundID*              outSystemSoundID)

• 實(shí)現(xiàn)案列

AudioServicesCreateSystemSoundID((__bridge CFURLRef)([NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"shake_sound_male.wav" ofType:@""]]), &shakingSoundID);

替換系統(tǒng)的播放音頻

• inSystemSoundID : 添加音頻到系統(tǒng)時(shí)標(biāo)記的ID

 AudioServicesPlaySystemSound(SystemSoundID inSystemSoundID)    

• 播放上面的一段音頻文件

AudioServicesPlaySystemSound(shakingSoundID);

實(shí)現(xiàn)控制消息的靜音和震動(dòng)功能

邏輯：
在設(shè)置頁面放置：switch按鈕鸡挠，控制靜音和震動(dòng)按鈕祈搜，
- 靜音：播放一段沒有聲音的音頻文件
- 震動(dòng)：播放一段震動(dòng)的音頻文件
使用場合：

• 聊天消息：
• 本地通知和APNS：

// 播放接收到新消息時(shí)的聲音

- (SystemSoundID)playNewMessageSound
{
    // 要播放的音頻文件地址
    NSString *audioStr = [[NSBundle mainBundle] pathForResource:@"right_answer" ofType:@"mp3"];
    NSURL *audioPath = [[NSURL alloc] initFileURLWithPath:audioStr];
    //    NSURL *bundlePath = [[NSBundle mainBundle] URLForResource:@"EaseMob" withExtension:@"bundle"];
    //    NSURL *audioPath = [[NSBundle mainBundle] pathForResource:@"right_answer" ofType:@"mp3"];
    // 創(chuàng)建系統(tǒng)聲音贸辈，同時(shí)返回一個(gè)ID
    SystemSoundID soundID;
    AudioServicesCreateSystemSoundID((__bridge CFURLRef)(audioPath), &soundID);
    // Register the sound completion callback.
    AudioServicesAddSystemSoundCompletion(soundID,
                                          NULL, // uses the main run loop
                                          NULL, // uses kCFRunLoopDefaultMode
                                          EMSystemSoundFinishedPlayingCallback, // the name of our custom callback function
                                          NULL // for user data, but we don't need to do that in this case, so we just pass NULL
                                          );
    
    AudioServicesPlaySystemSound(soundID);
    
    return soundID;
}

// 震動(dòng)

- (void)playVibration
{
    // Register the sound completion callback.
    AudioServicesAddSystemSoundCompletion(kSystemSoundID_Vibrate,
                                          NULL, // uses the main run loop
                                          NULL, // uses kCFRunLoopDefaultMode
                                          EMSystemSoundFinishedPlayingCallback, // the name of our custom callback function
                                          NULL // for user data, but we don't need to do that in this case, so we just pass NULL
                                          );
    
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}

實(shí)現(xiàn)搖一搖功能

• 設(shè)置app是否支持震動(dòng)功能

[UIApplication sharedApplication].applicationSupportsShakeToEdit = YES;

• 實(shí)現(xiàn)代理

-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event ;

• 代理實(shí)現(xiàn)方式

#pragma mark - Event Delegate
-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if(motion == UIEventSubtypeMotionShake) {
        // 播放聲音
        AudioServicesPlaySystemSound(shakingSoundID);
//        AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
        
        // 真實(shí)一點(diǎn)的搖動(dòng)動(dòng)畫
        [self shaking];
    }
