In my project I want to change application settings such as sound on/off and vibrate on/off for chat notification(Local Notification).
The Settings view look something like this:
How can I toggle between the sound and vibration from within the app.
I read in some S.O thread that the vibration is automatic with the local notification sound.
So in short I end up with this logic
Sound On, Vibrate On - Set any sound file.
Sound Off, Vibrate On - Set a silent sound file.
Sound On, Vibrate Off - ??
Sound Off, Vibrate Off - ??
How can I handle the last two situations?

I am working on app that can alert users for some critical things. I use local notifications to alert the user. On iOS, I find that the notifications will not ring if the phone is on vibrate. This is a deal-breaker for many users of the app but I have been putting that question off till now since I thought that iOS doesn't allow an app to play a sound if the app is in the background.
Music apps are able to play songs even when the phone is on vibrate by enabling the audio background mode but it doesn't allow you to schedule a song to be played at a certain time.
Lately I have seen that some apps are able to play a sound at a certain time even though the app is in the background. One such app is Alarmy alarm app. I don't think that they are playing the music via the local notification when the alarm expires because the music continues to play even after I clear the notification. From the local notification documentation, I understood that I am can't run any code when local notification fires till the user clicks on the notification. So, I can't start an audio player which may be able to play the sound in vibrate.
How are such apps able to play a sound even though the phone is on vibate and the app is in background in iOS?
There are few methods to implement this kind of functionality.For reference I recommend this link.
For actually playing the sound while the device’s ringer switch is set to vibrate
First off make sure to include the audio background mode in the capabilities, in order to play audio in the background.
Then,
Swift 4
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, with: [.duckOthers, .defaultToSpeaker])
try AVAudioSession.sharedInstance().setActive(true)
UIApplication.shared.beginReceivingRemoteControlEvents()
} catch {
NSLog("Audio Session error: \(error)")
}
Here we set the shared audio session’s category to AVAudioSessionCategoryPlayAndRecord, so that we can play sound, while the device’s ringer switch is set to vibrate.
The .duckOthers is specified to make other audio quieter, if there’s any mixable audio playing, so that our alarm can be heard. You can leave that out or use another option, if you prefer a different behavior.
The .defaultToSpeaker is specified, so that the volume would go to the speaker, where it’ll be much louder and should wake up our user with ease.
beginReceivingRemoteControlEvents makes it so that the app handles the remote control options, like the play/pause buttons on the lock screen, in order to make it easier for our user to mute their alarm, once they wake up.
The way this can be done (I have implemented this in my app) is by starting an AVAudioPlayer and specifying a specific time to play. So:
Enable background audio in the app capabilities.
Start and audio session with .playback mode, and start a player at the time you like it to play:
do {
//set up audio session
try AVAudioSession.sharedInstance().setCategory(.playback, options: [.defaultToSpeaker, .duckOthers])
try AVAudioSession.sharedInstance().setActive(true)
//Start AVAudioPlayer
player.play(at: time) //time is a TimeInterval after which the audio will start
}
catch {
...
}
This does not play silence in the background, which violates Apple's rules. It actually starts the player, but the audio will only start at the right time. I think this is probably how Alarmy implemented their alarm, given that it's not a remote notification that triggers the audio nor is the audio played by a local notification (as its not limited to 30 seconds or silenced by the ringer switch).
I'm creating an app where you can "send" vibrations to your contacts.
In IOS how do you set the sound for notifications from my app to vibrate, I want it to vibrate even when silent is off. Also I want the users to send custom vibration patterns, would that work or can you only play a sound once. It should work even when the app is not in background.
Try This Code :
1) AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
2) AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
I'm building a VoIP app on iOS and I'm using the AVAudioSession category of AVAudioSessionCategoryPlayAndRecord, which is recommended for VoIP apps that need to constantly play and record audio.
However, when the user switches their iPhone ringer to silent mode, the VoIP application will still play sound for an incoming call. This is not desired behavior.
Is there a way to prevent the incoming calls from playing audio when the user has their phone on silent, but still allow them to answer the call and have audio resume?
If you take a look here at the docs for AVAudioSession Categories, you can see that AVAudioSessionCategoryPlayAndRecord unfortunately does not obey the silencing of a phone, as seen below:
Your audio continues with the Silent switch set to silent and with the screen locked. (The switch is called the Ring/Silent switch on iPhone.)
If you want the audio to stop when you turn the phone to silent, you should use AVAudioSessionCategoryAmbient.
I think I found a solution that works for a VoIP application. If the phone is set to silent, I wanted the phone to show an alert and vibrate instead of playing the audible ring.
I can solve this by using local notifications and moving the sound out of the application and adding it to the notification itself. By specifying a sound file as part of the notification, iOS will handle whether it should play the audio or vibrate the phone. This is determined by the position of the Ring/Silent switch on the side of the phone.
Here's an Apple article on adding a sound to a local notification.
I know the ways for,
1.how to stop playing sound and stop vibrating(simultaneously) while push notification comes from server to iPhone device
2.Only playing vibrate with no sound.
but I did not find any way to "play only sound and stop vibrating when new push notification comes" on device.
Long answer: when the phone is set on vibrate, it is not possible to set it so that it will play a sound. The other way around is possible - vibrating without sound, when a push notification is received.
In my application I am using 'UILocalNotification` with a 30 sec audio file. I fire the notification when device is in lock mode. I tried to drag the notification on lock screen, then application will open at that Notification sound is playing, I need to recognize notification sound is playing or not when app is in foreground.
No good way, but you can use NSTimer. Start timer after show notification and make work when timer notify you. It will work, but use it only if any other resolution don't work.
