background-process

I have a problem keeping the GPS running in background. I succeded to keep the GPS running when the app is in background, but it stops sometimes. I noticed that it stops when i enter in a building and i stay there for 2-3 hours. "Stops" means that i don't receive any GPS point even though the location service icon is still on. Then when i get out i don't receive any points until I bring my application to foreground. I set the pausesLocationUpdatesAutomatically property to NO. So, everything works fine until i get into a location with weak gps signal. When i get out of that area i don't receive

I have an ASP.NET MVC4 website running and now i need some sort of background task that is continously running. But is this even possible? The MVC4 website is a sort of notifying system. Other websites can register a Callback URL on this website and this website should trigger that callback URL for a specified interval. So, for every hour for example. Normally the code of my website only becomes active when I visit a page. But in order to make this work I need a way to have my ASP.NET website to run in the background continously. So it can do its checks and make an HTTP call when necessary. It

I have a functional countdown timer. The problem is that I need to continue the countdown when the user puts the app in the background. Or suspends the app? I am not sure what the correct terminology is to describe this action. In other words, the user opens the app and starts the countdown. The user should be able to use other apps but the countdown still operate. Also, the countdown should be able to run forever until it finishes or when the user terminates running the app. Here is the code for my timer: class Timer{ var timer = NSTimer(); // the callback to be invoked everytime the timer

I feel that UIApplicationBackgroundRefreshStatusDidChangeNotification introduced in iOS 7 is of little use without supporting UIApplication delegate method. Because, the app is not notified when user has switch ON the background refresh state for my app. This is my notification handler... - (void)applicationDidChangeBackgroundRefreshStatus:(NSNotification *)notification { NSLog(@"applicationDidChangeBackgroundRefreshStatus with notification info = %@ and refresh status = %d", notification, UIApplication.sharedApplication.backgroundRefreshStatus); if (UIApplication.sharedApplication

PHPMailers is doing a fine job in sending emails from a gmail account. But it takes quite a bit of time, and the page won't show the response until the email has been sent. Any ways to send the email in the background so that I can provide a better user experience to the user? Thanks! Rafa The use of an email queue and php exec() is one of the best ways. It will trigger when needed (avoiding the use of CRONs), it's fast because it is called backgrounded, and immediate. 1. Email queue. Take all fields in a table's MySQL with an insert, something like: $queryIN="INSERT INTO email_queue (date

Im quite new to iOS programming and now want to implement a periodic background synchronization to synchronize my server data with client data. What I want to achieve is comparable with Androids SyncAdapter where you can define a time interval (for example each 30 minutes) and the system will trigger the defined task automatically in the background. Until now I could not find such mechanism for Swift 3.0 so I need to ask if somone has experience or some hints for me how I can achieve this. What I want to do sounds quite simple: When the app starts for the first time the app should setup a sync
