i have use mac os x 10.9.3 , xcode 5.1.1

in app have use mkmapview, it's working fine in ios 6.1, have stranger error display in console, such like,

can't render polygon (can't reserve indicies: 1482): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 570): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 30): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 390): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 330): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 18): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 30): featureid: 0 key: 0.0.1 (512) can't render polygon (can't reserve indicies: 18): featureid: 0 key: 0.0.1 (512) 

like this question.

i want know error , why displaying in ios 6.1 , how can solve it?

my code is:

self.mapview = [[mkmapview alloc] init]; self.mapview.frame = cgrectmake(30, 30, 140, 105); [self.mapview setmaptype:mkmaptypestandard]; [self.mapview setzoomenabled:yes]; [self.mapview setscrollenabled:yes]; [self.mapview setdelegate:self]; self.mapview.layer.borderwidth = 1; self.mapview.layer.bordercolor = [uicolor lightgraycolor].cgcolor; [self.scrollview addsubview:self.mapview]; self.pointannotation = [[mkpointannotation alloc] init]; [self setmapannotationandcallout]; /// custom method set annotation pin , callout  -(void)setmapannotationandcallout {     cllocationcoordinate2d thecoordinate ;     thecoordinate.latitude = [[self.dicofmap objectforkey:@"latitude"] doublevalue];     thecoordinate.longitude = [[self.dicofmap objectforkey:@"longitude"] doublevalue];      self.pointannotation.coordinate = thecoordinate;     self.pointannotation.title = @"title";     self.pointannotation.subtitle = @"subtitle";     int region = 8000;     mkcoordinateregion adjustedregion = [self.mapview regionthatfits:mkcoordinateregionmakewithdistance(thecoordinate, region, region)];     [self.mapview setregion:adjustedregion animated:yes]; }  #pragma mark - #pragma mark - mkmapview delegate methods  - (void)mapview:(mkmapview *)mapview didaddannotationviews:(nsarray *)views {     mkannotationview *av;     (av in views)     {         cgrect endframe = av.frame;         av.frame = cgrectmake(av.frame.origin.x, av.frame.origin.y - 230.0, av.frame.size.width, av.frame.size.height);         [uiview beginanimations:nil context:null];         [uiview setanimationduration:0.70];         [uiview setanimationcurve:uiviewanimationcurveeaseinout];         [av setframe:endframe];         [uiview commitanimations];     } }  - (mkannotationview *)mapview:(mkmapview *)sender viewforannotation:(id < mkannotation >)annotation {     static nsstring *reuseid = @"standardpin";     mkpinannotationview *aview = (mkpinannotationview *)[sender dequeuereusableannotationviewwithidentifier:reuseid];     if (aview == nil)     {         aview = [[mkpinannotationview alloc] initwithannotation:annotation reuseidentifier:reuseid];         aview.rightcalloutaccessoryview = [uibutton buttonwithtype:uibuttontypedetaildisclosure];         aview.canshowcallout = yes;     }     aview.annotation = annotation;      return aview; }  - (void)mapview:(mkmapview *)mapview didselectannotationview:(mkannotationview *)view {     [mapview deselectannotation:view.annotation animated:yes]; } 

i had same output in console on ios 6.1.

in case problem tried zoom out map based on coordinate (0.00000,0.00000), , created strange rendering problems only in first time opened map. after re-opened map worked correctly. when coordinate wasn't (0.00000,0.00000), worked.

maybe should check value of thecoordinate want be.
