问题 Using User Notification framework available in iOS 10 i tried to trigger notification whenever User enters specific geo location using UNLocationNotificationTrigger. When I tried test it through simulator by simulating the Geo location, the notification is not getting triggered, but Location manager returns the updated geo location. Should this be tested in real device instead of running it in simulator? 回答1: According to Apple Documentation : Apps must request access to location services and

问题 I want to get the Location object on Button press. I know the LocationListener callbacks, however they execute only after a particular time or distance. I want to get Location instantaneously. Are there any methods to do so. 回答1: You are welcome to call getLastKnownLocation() on LocationManager to retrieve the last known location for your requested location provider. However: that location may be old that location may be null Hence, your code will need to be able to cope with both of those

问题 I have images of malls that I need to use as maps for an app I am making. I have the GPS lat/long of the bottom corners of the map and I figured out the distance from the bottom GPS coordinates to what would be the top of the map image. How ever these are not straight up and down linear maps meaning I can't just plot my lat and long all nice and neat. I've tried using various formulas and I'm so close but I can't plot the top lat and long of the top left and right of the map. So far this is

问题 I have an Android app with a Google Map and automatic location updates via Google Play Services' new location API. Implemented just like this: https://developer.android.com/training/location/receive-location-updates.html I'm specifically trying to receive GPS / accurate locations. It works 100% perfectly and normally, GPS icon is on above, locations coming in every few seconds, no worries. The odd problem seems to be that if you switch to Google Maps, wait a second, then switch back to my

问题 I've got a spreadsheet of about 5000 user events associated with IPs, and I'm trying to use IP to determine location using just an Excel formula. The IPs in my log are structured as "dotted quads" (decimal notation). I figured VLOOKUP is the way to go here, so I downloaded WEBNet77's IPV4 IpToCountry database, which seems like a comprehensive and up-to-date resource (is there a better resource out there for this purpose?). The database includes about 140K rows of IP ranges, with the sheet

问题 I have been looking for an answer for this question for a long time and no one seemed to have an answer. I am trying to subscribe to location updates, using Google's latest FusedLocationProviderAPI. I have followed tutorial online and it works by getting my location every now and then using intentservice triggered by requestLocationUpdates. Moving on, I try to add pass a custom class of object "User" to my intentservice. This custom class would allow me to upload the location to my server for

问题 ios sdk has great region monitoring functions. I need something like that in android and i think we have two alternatives. Geofencing and LocationManager. Geofencing has really tidy examples and bugs , so i prefered LocationManager. Everyting works fine in LocationManager except one. If you add your current location as ProximityAlert , it immediatly fires "ENTERING" , but it is my current location , it doesnt mean that i entered this region. Because of that , it fires "ENTERING" each time i
