theSpan.latitudeDelta = 0.005;
theSpan.longitudeDelta = 0.005;

theRegion.center =  manager.location.coordinate;
theRegion.span = theSpan;

myMap.scrollEnabled = YES; 
myMap.zoomEnabled = YES; 

[myMap setRegion:theRegion];
[myMap regionThatFits:theRegion];

Answer 1

Don't you do anything in the main thread that would prevent the map tiles to load fully ?

Answer 2

Solved with SDK updated.

Answer 3

I've seen that you're using CLLocationManager. You need to be aware that the CLLocationManager delegate callbacks are called on a background thread. So you should not update the map (e.g. zoom, region etc.) from within the delegate callbacks.

Or you need to perform these task in a "performSelectorOnMainThread" block.
