如何建立不振动的iOS推力通知?
原标题：How can I create iOS push notifications that don’t vibrate?
I know how to create silent push notifications (with playing a sound file that is silent). I would also like to send a push notification that doesn t vibrate phone.
When setting silent sound file as suggested below phone still vibrates when it is locked or when the app is not active.
My payload that still vibrates:
{
aps = {
alert = {
"loc-key" = "SOME_KEY";
};
badge = 1;
sound = "silence.caf";
};
}
Is this possible?
问题回答
Omitting the sound key should do the trick:
{"aps":{"alert":{"loc-key":"SOME_KEY"}, "badge":1}
The docs state that "If the sound file doesn’t exist or default is specified as the value, the default alert sound is played.". What they don t say is that if you don t provide a sound key at all, no sound will be played. If no sound is played, the phone should not vibrate as well.
I did it this way: server send a push to device with sound file name which is silent. That s it.
Example:
Incomming payload from server:
{ aps = { "content-available" = 1; sound="silence.mp3" }; data-id = 1234; }
And device handle it in AppDelegate:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
NSInteger data_id= [userInfo[@"data-id"] integerValue];
NSLog(@"Data-id: %i", data_id);
//
// code...
//
// UIBackgroundFetchResultNoData/UIBackgroundFetchResultFailed/UIBackgroundFetchResultNewData
completionHandler(UIBackgroundFetchResultNewData);
}
when you register for push notification don t ask for sound type (UIRemoteNotificationTypeSound)
- (void)registerForRemoteNotificationTypes:(UIRemoteNotificationType)types
you can test this by manually removing the sound permission in the notification settings
[[UIApplication sharedApplication]registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge];
Please try to register for remote notifications using above code applicationDidFinsihLaunching method of AppDelegate
I ve faced with similiar issue. Vibration can be fixed by setting background fetch in project capabilities
I have to add in AppDelegate :
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
NotificationCenter.default.post(name: Notification.Name.init("didReceiveRemoteNotification"), object: completionHandler, userInfo: userInfo)
}
And check "Remote notifications" in the Capabilities "Background Modes".
Then I send a notification with only the data :
device.send_message(
messaging.Message(
data = data,
), app = FCMApp)
