iPhone：Mapview移动引脚问题

Question

I have Mapview and I successfully plot all pins on map and when I select a pin also add one button which is rightCalloutAccessoryView and when I click on button at that time I want to move all pins and selected pin display in center of mapview so please give me idea to develop this functionality..

Sorry for bad English.

Thanks in advance.

Answer 1

When the button is pushed, calculate the latitude/longitude range of all your pins, make an MKCoordinateRegion based on that, then use the MKMapView

- (void)setRegion:(MKCoordinateRegion)region animated:(BOOL)animated

To zoom to that region.
