如果应用程序在ios中处于活动状态时通知如何发出声音？

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { [[NSNotificationCenter defaultCenter] postNotificationName:@"MessageReceived" object:self]; UIApplicationState state = [application applicationState]; if (state == UIApplicationStateActive) { // NSString *cancelTitle = @"Close"; NSString *showTitle = @"Show"; // NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"New Order" message:@"You just received new order" delegate:self cancelButtonTitle:nil otherButtonTitles:showTitle, nil]; UILocalNotification *localNotifcation = [[UILocalNotification alloc] init]; localNotifcation.userInfo = userInfo; localNotifcation.soundName = UILocalNotificationDefaultSoundName; // localNotifcation.alertBody = message; localNotifcation.fireDate = [NSDate date]; [[UIApplication sharedApplication] scheduleLocalNotification:localNotifcation]; [alertView show]; } else { //Do stuff that you would do if the application was not active } } 

请给我一个解决方案，如果现在通知正在使用x-code 6.3，我怎样才能在应用程序运行时获得声音？

Answer 1

添加以下框架

 #include  

使用以下代码 –

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { UIApplicationState state = [application applicationState]; if (state == UIApplicationStateActive) { SystemSoundID soundID; CFBundleRef mainBundle = CFBundleGetMainBundle(); CFURLRef ref = CFBundleCopyResourceURL(mainBundle, (CFStringRef)@"mySoundName.wav", NULL, NULL); AudioServicesCreateSystemSoundID(ref, &soundID); AudioServicesPlaySystemSound(soundID); } else { // Push Notification received in the background } } 

或者您可以使用系统声音 –

 AudioServicesPlaySystemSound(1007); 

对于振动 –

 AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); 

在这里看到所有声音列表。

您可以手动添加声音文件，并在应用处于活动状态时播放。

 if ([application applicationState] == UIApplicationStateActive) { NSLog(@"active"); NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"alarm2" ofType:@"wav"]; NSURL *soundURL = [NSURL fileURLWithPath:soundPath]; AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &_mySound); AudioServicesPlaySystemSound(self.mySound); } 

如需更多默认声音，请查看以下答案： 播放系统声音而不导入自己的声音

试试这段代码。 将此代码放在AppDelegate .m中的AppDelegate

 SystemSoundID soundID; CFBundleRef mainBundle = CFBundleGetMainBundle(); CFURLRef ref = CFBundleCopyResourceURL(mainBundle, (CFStringRef)@"Voicemail.wav", NULL, NULL); AudioServicesCreateSystemSoundID(ref, &soundID); AudioServicesPlaySystemSound(soundID); 

这段代码完美地为我工作..
