I was working with XCode 4.3 and having a working code. But after upgrading to 4.4 i met with a problem. The problem is that current user location is not being showed on the iphone simulator. I mean the blue dot. And also my pins dissappeared and map is not focusing to the area i wanted. Do u have any idea about this problem?
Did you try this
self.mapView.showsUserLocation=YES;
