Passing geolocation fetched from the app to the UIWebView

Question

I\'m developing the iOS app and in one of the views I would like to include UIWebView with a page that contains a map (the address is: https://carsharing.mvg-mobil.de). The

Answer 1

You can call JavaScript on the page with UIWebView's

 stringByEvaluatingJavaScriptFromString:(NSString *)script

Answer 2

OK, I found the solution in the source code of PhoneGap how to inject JavaScript code to a standrad webview with the location fetched from CoreLocation:

int epoch = [newLocation.timestamp timeIntervalSince1970];
float course = -1.0f;
float speed  = -1.0f;
NSString* coords =  [NSString stringWithFormat:@"coords: { latitude: %f, longitude: %f, altitude: %f, heading: %f, speed: %f, accuracy: %f, altitudeAccuracy: %f }",
                        newLocation.coordinate.latitude,
                        newLocation.coordinate.longitude,
                        newLocation.altitude,
                        course,
                        speed,
                        newLocation.horizontalAccuracy,
                        newLocation.verticalAccuracy
                     ];

NSString * jsCallBack = [NSString stringWithFormat:@"navigator.geolocation.setLocation({ timestamp: %d, %@ });", epoch, coords];

[webView stringByEvaluatingJavaScriptFromString:jsCallBack];

Hopefully somebody else can profit from this code as well.
