I would like to get the blue bar when tracking in the background, but not when not.
My app uses location services all the time when active, so in iOS8 I use the requestWhenInUseAuthorization
on CLLocationManager
. Normally, the app stops tracking your location when you close it, but the user can choose the option to let the app track his location in the background as well. Therefore, I have the location
option for UIBackgroundModes
in the Info.plist file. That works perfectly: when switching to the background, the app keeps getting location updates, and a blue bar appears as a reminder that the app is using location services. All perfect.
But the problem is, that the blue bar appears also when the user has not chosen to track in the background. In that case I simply stop location updates from the AppDelegate when entering the background:
- (void) applicationDidEnterBackground:(UIApplication *)application
{
if (!trackingInBackground) {
[theLocationManager stopUpdatingLocation];
}
}
The Blue bar is shown only for a second after closing the app, but it still looks pretty irritating.
I know that using requestAlwaysAuthorization
instead of requestWhenInUseAuthorization
will solve the issue, but then I will not get any blue bar at all, also not when tracking in the background is actually on.
I have tried to stopUpdatingLocation
already in the applicationWillResignActive:
method, but that makes no difference.
Does anybody know how to get the blue bar when tracking in the background, but not when not?
The blue bar only show when you enable
Background Location Updates
and requestwhen-in-use authorization
in iOS 8.Sounds like location manager can't stop immediately. So the blue bar will appear until location manager stop completely. Or maybe it's just a bug like Keith said.
To show blue bar on header that your app is using location when pressing home button you have to set Privacy - Location When In Use Usage Description in Plist file
when you use self.locationManager.requestAlwaysAuthorization() then it will not display blue header
you need only use
self.locationManager.requestWhenInUseAuthorization()
then it will display blue header when you app is in background that your app is using Locationyou have to also set background mode in capabilities in target for location
This is not a bug, you still have an active location manager somewhere in you app. Do you have a map view with
showsUserLocation = YES
for example? That could be it.I went over my project thoroughly and when i stopped all location managers the bar disappeared when it should.
If you follow steps below, Blue bar will not appear in background mode
We frequently report things to Apple, and sometimes they actually act upon it. Exactly to prevent the blue bar from appearing shortly as described in the question, Apple has introduced a new property on
CLLocationManager
in iOS-9. Set it at the moment you know you will need the location in the background:or, in a backward compatible way:
in Swift:
If this property is not set, then the Blue Bar will not appear when exiting the app, and the user location is not available to your app. Note that in iOS 9, you must set the property in order to be able to use location in the background.
See the WWDC video for Apple's explanation.
To show blue notification you need to add Privacy - Location When In Use Usage Description in Plist file (this is important, with Always Location the blue bar didn´t appear ever)
then star the location: locationManager.startUpdatingLocation()
Also override methods:
Remember the import!!:
And also remember the Delegate (CLLocationManagerDelegate):
