mkmapview

Hello all,

I have some troubles with iphone 3G and Mkmapview. After a certain random time, my application freeze. When I launch with performances tool, I can see that the application a lot of time to retrieve map tiles in cache.

19.6 7006 Foundation +[NSURLConnection(NSURLConnectionReallyInternal) 18.5 6613 GMM GMM::TileCachePrivate::runCacheThread()

Its seems that the MkMapView component launch several threads to load the tiles in caches. How I can avoid this behavior ?

The behavior seems to not make troubles on 3GS.

Thanks
