//开启免打扰
MPushOptions *options = [[EMClient sharedClient] pushOptions];
options.noDisturbStatus = EMPushNoDisturbStatusDay;  //全天免打扰
options.noDisturbingStartH = 0;
options.noDisturbingEndH = 24;
[[EMClient sharedClient] updatePushNotificationOptionsToServerWithCompletion:^(EMError *aError) {
    if (!aError) {
        NSLog(@"开启免打扰成功");
    }else{
        NSLog(@"error:%@", aError);
    }
}];

//关闭免打扰
MPushOptions *options = [[EMClient sharedClient] pushOptions];
options.noDisturbStatus = EMPushNoDisturbStatusClose;  //关闭免打扰模式
[[EMClient sharedClient] updatePushNotificationOptionsToServerWithCompletion:^(EMError *aError) {
    if (!aError) {
        NSLog(@"关闭免打扰成功");
    }else{
        NSLog(@"error:%@", aError);
    }
}];

以上设置完后，你会发现当开启免打扰后仍然可以收到推送，那是因为还需要在playSoundAndVibration和showNotificationWithMessage:(EMMessage *)message方法中进行推送免打扰设置状态的判断，当状态为EMPushNoDisturbStatusClose时才执行推送或播放提示声音。

{
    EMPushOptions *options = [[EMClient sharedClient] pushOptions];
    if (options.noDisturbStatus == EMPushNoDisturbStatusClose) {
        NSTimeInterval timeInterval = [[NSDate date]
                                       timeIntervalSinceDate:self.lastPlaySoundDate];
        if (timeInterval < kDefaultPlaySoundInterval) {
            //如果距离上次响铃和震动时间太短, 则跳过响铃
            NSLog(@"skip ringing & vibration %@, %@", [NSDate date], self.lastPlaySoundDate);
            return;
        }
        
        //保存最后一次响铃时间
        self.lastPlaySoundDate = [NSDate date];
        
        // 收到消息时，播放音频
        [[EMCDDeviceManager sharedInstance] playNewMessageSound];
        // 收到消息时，震动

    }
}

        }

        if (playSound) {
            notification.soundName = UILocalNotificationDefaultSoundName;
        }
