Run background location updates in ViewController or separate object?

ios,swift,cllocationmanager,ibeacon

For background location updates your app may not be running at the time the update is generated. If you've been terminated then you may be re-launched as a result of the location update. In that case your app delegate is probably the best candidate for the location manager delegate. You...

Beacon / IOS CLLocationManager get current region

You can use the locationManager:didDetermineState:forRegion: callback, which tells you if you are either Inside, Outside or Unknown. You can force yourself to get a callback by calling locationManager.requestStateForRegion(region) when your app starts up. See more here: https://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLLocationManagerDelegate_Protocol/#//apple_ref/occ/intfm/CLLocationManagerDelegate/locationManager:didDetermineState:forRegion:...

iOS: When I try to get CLLocation by click, there is most of the time a “big” lag

ios,objective-c,core-location,cllocationmanager

The time interval between update calls to the location manager delegate is variable, so the behavior you're experiencing is expected. CLLocationManager has a property called location which returns the last known location of the user (or nil if you've never used the Location Manager in the app). Instead of waiting...

Accessing CLLocationManager varibale from one viewcontroller to another viewcontroller

When you DashBoardViewController *dash=[[DashBoardViewController alloc] init]; it creates a new DashBoardViewController instance. You can define locationManager in AppDelegate and access directly to it from anywhere in your code.

Remove CLBeaconRegion from monitoring depending on current location

ios,geolocation,cllocationmanager,ibeacon,clbeaconregion

a CLBeaconRegion represents N bluetooth beacons with the same uuid. an ibeacon has no gps coordinate. it has an RSSI value (the signal strength) and a 'calculated' proximity property but no location. same as a wifi router ;) there are services to associate beacons/wifi routers with a GPS location but...

Using CLLocationManager in SpringBoard, but got the error with:depending on legacy on-demand authorization, which is not supported for new apps

ios8,location,cllocationmanager,theos,springboard

It's all due to iOS 8 changes. On previous iOS versions at least locationd had com.apple.locationd.preauthorized entitlement which gives access to location without user permission. Now even locationd doesn't have it. Same with SpringBoard and imagent. Of course, being locationd it can access location through it's own APIs - locationd...

Not being prompted to enable Location Services in App

ios,objective-c,cllocationmanager,cllocation

Lots of useful comparisons here: http://nevan.net/2014/09/core-location-manager-changes-in-ios-8/ Also, silly question time: you mix _location and self.location but you don't show your property/synthesize code. Are you sure you're operating on the same object?...

CoreLocation Swift

Alerting user that the app still uses Location Updates (GPS)

ios,ios8,gps,core-location,cllocationmanager

In iOS8 and later requestWhenInUseAuthorization puts up the blue bar. It's put up by Apple to remind the user of the device that the app is using CoreLocations. On the other hand if you use requestAlwaysAuthorization blue bar wont' show, but Apple will periodically remind users that your app is...

How can I eliminate false states of my monitored region in the location manager's didDetermineState method?

ios,cllocationmanager,geofencing

I tried this earlier and it didn't seem to work, but then I changed the delegate of my location manager and it seems to work now in the didDeterminState method. CLLocation* location = [self.locationManager location]; NSDate* eventDate = location.timestamp; float accuracy = location.horizontalAccuracy; NSTimeInterval howRecent = [eventDate timeIntervalSinceNow]; CLLocation* regionLocation...

How to get background updates for iBeacons without using locationManager didEnterRegion

ios,objective-c,cllocationmanager,ibeacon

Those docs are misleading because they are meant to cover monitoring for geofence regions (e.g. CLCircularRegion) as well as beacon regions (CLBeaconRegion). The Heuristics you describe apply only to geofences. For beacons, detection times on entering a region vary depending on the hardware. On iPhone 4S devices, beacon region entry...

Location class using CLLocationManager in swift

ios,swift,cllocationmanager,cllocation

The problem is that locUtil, to which you have assigned your LocationUtil instance, is an automatic variable — that is, it is local to the viewDidLoad function. Thus, when viewDidLoad runs, locUtil (and your LocationUtil instance) comes into existence, exists for one more line, and vanishes in a puff of...

iOS8 background standard-location updates after termination

ios,objective-c,core-location,cllocationmanager

If you're using CoreLocation framework in your app in Xcode7(pre-released),and you may notice that there is a newly added property called allowsBackgroundLocationUpdates in CLLocationManager class. This new property is explained in the WWDC session "What's New in Core Location". The default value is NO if you link against iOS 9....

Setting Parse PFGeopoints on a map only viewable for current user

parse.com,mkmapview,cllocationmanager

Easiest way to do this is to have a column in the database named visible. You should only query for users that have it set as true. When you don't want a user to be seen, set his visible column to false.

Is there any good way to know when CLLocationManager's startMonitoringForRegion has completed?

of course yes. in the CLLocationManagerDelegate you will find - locationManager:didStartMonitoringForRegion: . here you will find the full delegate description.

CLLocationManager time format?

nsdateformatter,cllocationmanager

Try using this as your format: @"yyyy-MM-dd HH:mm:ss zzz" This now works fine for me: This is swift in the picture, but the important part is the date format string. That is language independent and I just wanted to show you that it was working. Replacing the format string in...

How to convert PFGeoPoint to CLLocation

You need to explicitly create the CLLocation instance using initWithLatitude:longitude: with the latitude and longitude from the PFGeoPoint. There is only a convenience method for creating a PFGeoPoint from a CLLocation, not the other way round.

App get in LocationManager approval loop

objective-c,sms,xcode6,mkmapview,cllocationmanager

You could init the CLLocationManager before requesting authorisation, but I would also recommend against just assigning for permission right away.

Getting user's current location coordinates: MKMapItem vs CLLocationManager

ios,location,mkmapview,cllocationmanager,mkmapitem

For an MKMapView object to be showing user location you will have to have requested authorisation for iOS8 (ie using requestWhenInUseAuthorization on a CLLocationManager object). MKMapView objects have a didUpdateUserLocation: delegate method you could use receive user location updates, but this may fire off repeatedly until it reaches the accuracy...

How to use MKMapView's “Shows User Location” in iOS8?

Where to store app location data?

Why does didUpdateLocations: only have one location after locationManagerDidResumeLocationUpdates:

the didFailWithError or didChangeAuthorizationStatus methods are not being called Those are delegate methods.
