我一直找不到有关该错误的任何信息,并且完全感到困惑.我看不到真正的视觉差异,也没有其他错误.任何人都知道这是怎么回事吗?
I've been unable to find anything regarding the error, and am completely baffled. There are no real visual discrepancies that i can see, and there are no other errors. Anyone got any idea what this is all about?
推荐答案
I also had the same problem once in iOS6.1.
I was zooming out the map based on a coordinate which was (0.00000,0.00000).
In my code:-
CLLocationCoordinate2D theCoordinate ;
theCoordinate.latitude = [[self.dicOfMAP objectForKey:@"latitude"] doubleValue];
theCoordinate.longitude = [[self.dicOfMAP objectForKey:@"longitude"] doubleValue];
self.pointAnnotation.coordinate = theCoordinate;
the value of theCoordinate was(0.0,0.0).
So check the value of coordinate.
