    <p>I need to fit a certain bounds within a map. I get the bounds from calling the google geocoder and reading the viewport property which looks like:</p> <pre><code>{ northeast = { lat = "30.4212235"; lng = "-97.486942"; }; southwest = { lat = "30.1128403"; lng = "-97.99917959999999"; }; } </code></pre> <p>I then convert these into CLLocationCoordinate2D</p> <pre><code>NSDictionary *viewport = [[[results objectAtIndex:0] objectForKey:@"geometry"] objectForKey:@"viewport"]; NSDictionary *NEDictionary = [viewport objectForKey:@"northeast"]; NSDictionary *SWDictionary = [viewport objectForKey:@"southwest"]; CLLocationCoordinate2D SWCoordinate = CLLocationCoordinate2DMake( [[SWDictionary objectForKey:@"lat"] floatValue], [[SWDictionary objectForKey:@"lng"] floatValue] ); CLLocationCoordinate2D NECoordinate = CLLocationCoordinate2DMake( [[NEDictionary objectForKey:@"lat"] floatValue], [[NEDictionary objectForKey:@"lng"] floatValue] ); </code></pre> <p>I know I need to generate a MKMapRect (or MKMapRegion, whichever is easier) from these coordinates and then [mapView setVisibleRect:newRect animated:YES] (or [mapView setRegion:newRegion animated:YES] but I'm not quite sure how to get there. I need a method to convert the bounds into the proper data structure, something like:</p> <pre><code>- (MKMapRect) mapRectThatFitsBoundsSW:(CLLocationCoordinate2D)sw NE:(CLLocationCoordinate2D)ne { // CGFloat x = ?? // CGFloat y = ?? // CGFloat width = ?? // CGFloat height = ?? MKMapRect mapRectFromBounds = MKMapRectMake(x,y,width,height); return mapRectFromBounds; } </code></pre> <p>Any thoughts?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
