How to find the lat long from a city name [closed]

由 萝らか妹 提交于 2019-12-08 13:56:08
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I have a city name but not the lat long values for that city. How would I go about getting the lat and long values from a city name and then save it to a variable in iOS? I've seen the geo reverse coding but the examples I've seen do the opposite to what I'm looking for (they find the city name from the lat/lon)

问题 I have been having trouble with location services in iOS 11 for both "Allow while Use" and "Always Allow". Works without issue in iOS < 11. Followed this thread in trying to fix but still doesn't work. What am I missing? Thank you in advance. I have UITabViewController in my app and a UINavigationController inside each tab. I have a singleton LocationManager class. I'm setting my UINavigationController's RootViewController as delegate the ViewController's viewWillAppear to receive location

CLLocationManager only monitors regions the first time the app is run after install

由 爱⌒轻易说出口 提交于 2019-12-08 07:35:42
问题 I have an iOS app which is a tabbed application, with 3 view controllers, all of which need to know when the phone enters specific geographical regions. The regions which we monitor for are supplied at run time over a web interface, so we need to periodically clear the regions that the CLLocationManager is monitoring for and add new ones. The CLLocationManager object is a member variable of a singleton class which manages the connection with the web server as well. The problem that I have is

CLLocationManager holds cache value

由 冷暖自知 提交于 2019-12-08 05:35:47
问题 This part of code of CLLocationManager is used to calculate the distance travelled. But the location cache is not removed even after using timeIntervalSinceNow . - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { if(newLocation != nil && oldLocation != newLocation) { tempNewLocation = newLocation; tempOldLocation = oldLocation; } NSLog(@"New Location Found"); NSLog(@"- Latitude: %f", newLocation

Reducing the threshold of didEnterRegion

由 点点圈 提交于 2019-12-08 05:14:03
问题 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

问题 I have some code that find the user location and return it into a Label.
