clregion

I'm currently working on an app that I want for my app to detect a beacon in background mode just when it gets close to it(Immediate). Based on articles that I've read it cannot be done with didEnterRegion and I should use ranging while it's running in the background mode(Location Update). is there any solution that directly reduces the didEnterRegion threshold? or Should I use the other method? and if that's the case does it work like didEnterRegion but with a limited range of RSSI? does it work when my phone entered the region and it's locked and the screen is off? Monitoring APIs give you

I have been doing some iOS development for a couple of months and recently I am developing a bus app. I am currently mimicking the bus' movements and set up multiple annotations on the bus stops. For test purposes, I have setup just one bus stop and am trying to monitor when the bus has entered this region and exited as well. Strangely, my didStartMonitoringForRegion method is called perfectly but neither the didEnterRegion nor didExitRegion methods are called. Every time I run the program, the bus pretty much passes the stop without prompting me so. Could someone explain to me why this is

From what I can interpret from the runtime requirements of sample region monitoring code of Apple , region monitoring is available on iPhone 4, iPad 2 Wifi + 3G or later. So I'm assuming that it's not available on iPad1 with 3G, or iPhone 3G/3GS. Is this a correct interpretation? I cannot test this since I don't have all those devices and I couldn't find an official documentation about this. PS: I know that I can check for it in the code by calling regionMonitoringAvailable method but I need this information to decide for the architecture of my app, so I need to know this upfront. From what I

I have been unable to work out how to handle a scenario where the phone is already inside a region when startMonitoringForRegion is called? Other questions have suggested calling requestStateForRegion inside didStartMonitoringForRegion this then calls the method didDetermineState: forRegion: . So the code looks something like this: - (void)viewDidLoad { //location manager set up etc... for (Object *object in allObjects){ CLRegion *region = [self geofenceRegion:object]; [locationManager startMonitoringForRegion:region]; } } - (void)locationManager:(CLLocationManager *)manager

Since the depreciation of initCircularRegionWithCenter:radius:identifier: , how would you define the region to be monitored using CLLocationManager ? Since CLCircularRegion is a subclass of CLRegion , you can just cast the instance. CLCircularRegion *region = [[CLCircularRegion alloc] initWithCenter:theCenter radius:theRadius identifier:theIdentifier]; // Then cast the instance for use with your CLLocationManager instance [manager startMonitoringForRegion:(CLRegion *)region]; 来源： https://stackoverflow.com/questions/19205210/how-do-you-use-clregion-in-ios-7-since
