IOS: zoom in mapkit for two annotation point
ios, mapkit, xcode
Solution
Yes, it is possible. After adding the second annotation. This sample code should work for any number of annotations:
MKMapRect zoomRect = MKMapRectNull;
NSArray *annotations = [mapView annotations];
for (MKAnnotation *annotation in annotations) {
MKMapPoint annotationPoint = MKMapPointForCoordinate(annotation.coordinate);
MKMapRect pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0, 0);
if (MKMapRectIsNull(zoomRect)) {
zoomRect = pointRect;
} else {
zoomRect = MKMapRectUnion(zoomRect, pointRect);
}
}
[mapView setVisibleMapRect:zoomRect animated:YES];
Problem
I want to know if there is a way to have a dynamic zoom when I set in my mapview the blue dot (my position) and another pin...when I load mapview I want to show these two point in the same frame...is it possible? thanks
