Question

MKMapView reload/refresh on 3.1.2 and upwards

Answer 1

A:

Hi,

I suppose the map's loading is triggered by the user dragging the map so you could use the mapView:regionDidChangeAnimated: callback and include your game code in it.

Thanks for the help, unfortunately this is where the problem lies. The maps loading is triggered by a button connected to an IBAction which gives the map a region to display. The reason I need to use the mapDidFinishLoading callback is because I have a timer which can only start when the map is fully loaded. Any other ideas?Many thanksJules

Then you could use the mapViewWillStartLoadingMap: callback. If mapViewDidFinishLoading is not called I suppose that one isn't called neither.Start your timer in mapView:regionDidChangeAnimated, re-init it in mapViewWillStartLoadingMap: and start it again in mapViewDidFinishLoading: Is it a good workaround ?

Hi, this wont work either as none of the maps delegate functions are getting a call back. This only happens when the needed location has already been loaded at some point so what I really need to do is either reload the map somehow or flush the cache somehow??Many thanks againJules

Answer 2

A:

Don't know if you still need this, but I had a similar problem with viewForOverlay not being called. Actually it eventually got called, but too late for what I needed.

using the following it updated when I needed it to -

[self.map setVisibleMapRect:myMapRect];

Hi, I did try this but it didnt help in my case. In the end I just changed the way my game logic worked, not ideal but it works now. Cheers
