I want to set a music which is longer than 30sec as notification soound. But after searching about this I came to know that it is not possible to add these type of music as notification sound. notification sound must be in 30sec longer otherwise it will not play music. Now how can I add more than 30sec longer music as notification sound?
I had a similar issue for my alarm app as well. What I did was a workaround when your app is in background. You play a music file in your code in background and increase the volume of the device to maximum. You can play as much longer music file as you want. Stop playing the music when someone clicks on the notification.
The only problem with this is that your app should not be killed or terminated.
Is there a way to get the MPMusicPlayerControllerNowPlayingItemDidChange notification while the app is in the background?
I have an app that needs to be able to pause the music once a song has ended while in the background or when the screen is locked. I'm using a systemMusicPlayer to play the music.
I've tried adding the audio background capability and including a call to beginBackgroundTask in my applicationDidEnterBackground but that doesn't work for extended periods of time.
When in background, your app might be killed at any time, so you do not want to depend on acting in background.
How I understood, what you want to achieve is that when your app goes to background, the currently playing music goes on but stops after the currently playing song finished.
MPMusicPlayerController.systemMusicPlayer() is playing a queue of songs ("Playlist"). So I would try to manipulate this queue in applicationWillResignActive() to not have a song after the currently playing one .
I did not test this and I am not sure whether or not this is possible through public API.
I have the following situation in my application:
I have a music system in my application and I used MPMusicPlayerController to play music; every thing is working fine until now.
My problem: When a user starts playing music in my application and after some time it terminates, music cannot be stopped because I'm using the [MPMusicPlayerController systemMusicPlayer] object. I know there is another option which is applicationMusicPlayer, but it stops playing music in background, which doesn't satisfy my requirements.
How can I stop the music from playing when the application is terminated by user?
I have some code that attempts to stop it in applicationWillTerminate: but it only works in some situations:
If I press home button twice and terminate the app from the multitasking UI, then the app can stop the music player.
If I press the home button once and then go to the home screen, and after that I press the home button twice and terminate the application then it can not stop my music player.
I tried to put a breakpoint in applicationWillTerminate: but in the second example (from above), the application crashed and did not execute my code, unlike in the first situation.
UPDAT
And I know that when I use MPMusicPlayerController background mode is not required because it starts music in the native music player.
Any help would be appreciated.
Unfortunately your only option based on your requirements is to play the audio using your own app, AVAudioPlayer for example and set the audio background mode requirement.
As there is no way of receiving a notification when your app is terminated by the OS or by the user, you have no way around it, you will not be able to stop the system or application player from your process.
Registering for NSUncaughtExceptionHandler wont catch SIGKILL or SIGSTOP either so you cannot rely on the system music player.
This shouldnt be a problem though as its easy to setup audio playback in your app. If you are using the system player so that the user can play their own music, you should use a picker and access their music library so that they can choose the music.
In this case:
If I press the home button once and then go to the home screen, and after that I press the home button twice and terminate the application then it can not stop my music player.
You have to register application in the background mode.
fileprivate var backgroundTask: UIBackgroundTaskIdentifier = .invalid
func registerBackgroundTask() {
self.backgroundTask = UIApplication.shared.beginBackgroundTask {
//TODO
}
}
Call it in AppDelegate
Hope to help you
Is it possible to start audio play when app is in the background?
When my app is in the background , it calls the method to play the sound but AvAudioPlayer doesnt play.
Ive gone through various links on the web regarding this but all I could find is how to continue playing audio when app goes in the background. So does this mean we can't start the audio play in the background?
Thanks in advance :)
I think what I'm looking for is the combination of existing settings that I can't quite put together in the right order. I have an app that plays sound clips using AVAudioPlayer. There is a start/stop button.
I would like any other apps' audio to continue until my app actually needs to play something.
When my app is launched with some iTunes music playing, that music continues correctly. When I press play in my app, the other audio correctly stops, and my app plays. I stop my player, switch back to the music app, and press play again. But now when I switch back to my own app, the music stops immediately.
I would like it to again wait until it needs to play something before killing the music app.
My best guess is that once I've used the player, it is in some kind of 'I need audio' state, and remains in that state. How do I resign this state?
