问题
I have a webview based application and when I access http://maps.google.com, my webview is not passing the location as Safari does. I know CLLocationManager is needed, but do I get a callback when a webpage (maps.google.com) wants access to my device location? How do I respond back with the coordinates to the webpage from my WebView?
回答1:
The webview will start monitoring the location automatically, however since iOS 8 location access requires the NSLocationWhenInUseUsageDescription description in your info plist to be set.
If this has been done, it will prompt the user automatically to allow location access.
