My application is based on Event according to user current location. when i start my application Splash screen comes for 3 or 4 second .. then during splash screen i m getting current location of device and according to this current location i am displaying Event list..
But at the first time i m not able to get current location during the splash screen .after some time i am getting current location successfully for other screen.
In BB device there is GPS system and when we press device Menu key it will be refresh and get our current location. and it is display there. so is there any way to get quick current location from this GPS system (device system) which is displaying Latitude and Longitude there.
Thanks in Advance !!!
You can get last know location which will be immediately. But who know how far user is now.
Cell tower method will be also quick. But it also is not accurate as you probably expected.
As I remember there is 30-80 secs while device gets accurate location (if it's possible).
So I would suggest you to use available location with less accuracy and update list as you get more accurate one.

The output geo coordinates are only accurate on first load, the problem is when the iPhone screen times out and the locations services also timeout. And if I open safari again the geo coordinates are off by 100's of meters. The same thing happens if I push safari app to background. The problem is fixed if I reload the safari tab requesting geolocation or if I clear safari app cache and open up safari again. Why is this happening? My use case involves showing the user an arrow that guides to destination. Thus it is likely the phone times out occasionally for user that leads to location services timeout. iOS chrome does not mimic this behavior and work as expected i.e geo coordinates are always accurate event after tab in focus and /or screen timeout.
I don't know why this happens exactly, but it's happening to me too. I was able to get around the issue by using window.setInterval to call a function every 5 seconds or so that checks whether the location has been updated. If it hasn't, then the function stops and restarts the geolocation watch.
The restarting of the geolocation watch has the same effect as reloading the page, i.e. the accuracy becomes much better again, and location updates resume. Hope that helps!
I have a client requirement to monitor a region (say MyHome). To alert the user when he leaves MyHome and reaches back to the location. I can handle it pretty easily using the region crossing delegate methods:
locationManager:didEnterRegion:
locationManager:didExitRegion:
My question is, what will be the scenario if my device is off when I am at MyHome location. I leave the location MyHome, move to a different place and switch on my mobile. Will I get the locationManager:didExitRegion: delegate method fired when I launch the app back and thus will be able to notify that I am away from the region. OR will I have to do anything else to get this possible?
First of all monitoring region is not made for such small area to monitor. You may not get actual results. Now, the answer of your question, yes. It is possible. When you will start your device, you will have delegates method to get hit.
I'm developing an iOS map application, so it's essential to receive location data consistently.
What is happening now is that the system allows the to app load the map and that's it!
The location getting instruction seems to freeze, even the network traffic indicator at the top bar disappears. Simply when I go to Settings->Privacy->Location Updates, switch off location updates for my app and then switch it back on. The map loads the current location.
What could be the possible causes to this?, please advice.
Use:
[_mapView setUserTrackingMode:MKUserTrackingModeFollow animated:YES];
This will smoothly follow the users current location. If you drag the map it will even set the tracking mode back to MKUserTrackingModeNone which is usually the behaviour you want.
I am trying to set a bounds between the users location and a selected marker. I can set everything up properly but when I try to use the users location (mapView_.myLocation.coordinate) it says the lat and long are both 0. I did create a button to center the camera on the users location and it gets the lat and long just fine. Does not make any sense to me. Also I don't have a device set up to test so I am using xcodes iOS simulator with a location put into the simulator (is that where my problem is?). Any ideas?
Are you trying to access myLocation.coordinate from loadView or similar, ie when the app first starts up?
Generally when enabling location services the app doesn't receive a location update immediately, it comes through after some delay. So it's possible that myLocation.coordinate won't be valid in loadView, but will have a value set some time later (which is why it works with your button).
You could perhaps listen for changes to myLocation, and then set your bounds when it changes to something.
I'm learning to develop iOS apps and I try them on simulater only. Now, in my app I use CLLocationManager to get my current location coordinates. But when I run the app no matter where I am I get the same results for all the coordinate values(altitude,longitude,latitude). They do not change even if I move to another location. What I wonder is how does CLLocationManager get values? If it does not work on simulater then where do the values that never change come from? According to the coordinates I guess it's a default value that shows London if no coordinates are available.
Try Resetting the iOS Simulator, erasing all applications and settings.
And when you run CLLocationManager using application, it will probably ask for permission to use location, something like what you would see in you device.
I've been using iOS Simulator, and it gives location of my computer for the simulator all the time. I guess it's affected by your internet connection and IP address. Since many computers don't come with GPS, it's the only way to know the location of the computer.
The simulator always gives the location of Apple headquarters at Cupertino. It does not use computer's gps or location.
Simulator may use skyhook to check your location which is bounded to WiFi hotspot (if it was added with it's coordinates) and if you move in radius of WiFi coverage than your location won't be changed at all.
On the menu bar, go to Debug, then select Location, Custom Location and then you can input coordinates to simulate from. The Simulator will not always provide you the same feedback as a device would.
