Thanks Rolf. Would I have found that if I searched a bit more (it was 10pm on a Sunday night when I wrote the email)?
If not, I'll throw a blog post up about it. Thanks!

That, along with how events works (by implementing an internal delegate type), is what's causing the update event not to fire. Calling this method causes the location manager to obtain an initial location fix (which may take several seconds) and notify your delegate by calling its locationManager:didUpdateLocations: method. (In iOS 5 and earlier, the location manager calls the locationManager:didUpdateToLocation:fromLocation: method instead.) Here's a patch (from one of our sample) that shows how to deal with this (using events). + if (UIDevice.CurrentDevice.CheckSystemVersion (6, 0)) { + iPhoneLocationManager.LocationsUpdated += (object sender, CLLocationsUpdatedEventArgs e) => { + UpdateLocation (e.Locations [e.Locations.Length - 1]); + }; + } else { + // this won't be called on iOS 6 (deprecated) + iPhoneLocationManager.UpdatedLocation += (object sender, CLLocationUpdatedEventArgs e) => { + UpdateLocation (e.NewLocation); + }; + } [this is from one of our internal bugs, which Sebastien tracked down to this issue] Rolf On Sun, Sep 16, 2012 at 11:03 PM, Nic Wise <[email protected]> wrote: > Hi there > > I have some location code which has been working for ages.
