奇怪的错误:无法呈现多边形

我使用MKMapView总共显示约700个注释。 我的问题是,有时候我得到这样一个巨大的日志:

我一直无法find任何有关错误的信息,而且我完全不知所措。 没有真正的视觉差异,我可以看到,也没有其他的错误。 任何人都知道这是关于什么?

 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.
