Significant location change

Question

I have tried the significant location change in the latest iOS 8 update but the Core Location manager method

- (void)locationManager:(CLLocationManager *)manager
     didUpdateLocations:(NSArray *)locations

is never called.

When using method startUpdatingLocation the method above is called.

Everything worked in iOS 7 for the app. I need to update to iOS 8.

Share your experience.

Answer 1

I'm going to guess that you're not following the instructions here:

https://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLLocationManager_class/index.html#//apple_ref/occ/instm/CLLocationManager/startMonitoringSignificantLocationChanges

Events are going to be accumulated while your app is not running. Your app launches and must immediately create a location manager and start significant location updates all over again in order to receive that accumulated information.

如果要更新到iOS 8，请确保在属性列表（.plist）文件中进行更改：NSLocationWhenInUseUsageDescription和/或NSLocationAlwaysUsageDecription： http ://matthewfecher.com/app-development/getting-gps-location-using-core -location合IOS-8-VS-IOS-7 /
