I created a project based on your CalloutMapAnnotationView demonstrating a IB based solution. Arrow keys animate motion of the location annotation and it’s callout annotation. The callout now also automatically resizes based on the supplied contentView, and the view is loaded from a separate nib. Good luck! https://github.com/jacobjennings/JJMapCallout
One problem with the code by Paul Shapiro is that it doesn’t deal with when you add annotations below where the user is looking at the moment. Those annotations will float in mid-air before dropping because they are moved into the user’s visible map rect. Another is that it also drops the user location blue … Read more
In the showDetails: method, you can get the pin tapped from the map view’s selectedAnnotations array. Even though the property is an NSArray, just get the first item in the array since the map view only allows one pin to be selected at a time: //To be safe, may want to check that array has … Read more
For some reason (possibly a bug), the path property returns NULL in the current release of iOS 7. A workaround is to construct your own CGPathRef from the points of the polygon. With this method, you don’t need a reference to the MKPolygonView or the MKPolygonRenderer. For example: CGMutablePathRef mpr = CGPathCreateMutable(); MKMapPoint *polygonPoints = … Read more
First make your view controller implement the MKMapViewDelegate protocol and declare the properties you will need: @property (nonatomic, retain) MKMapView *mapView; //this is your map view @property (nonatomic, retain) MKPolyline *routeLine; //your line @property (nonatomic, retain) MKPolylineView *routeLineView; //overlay view then in viewDidLoad (for example, or wherever you initialize) //initialize your map view and add … Read more
There is an even easier solution. Create a custom UIView (for your callout). Then create a subclass of MKAnnotationView and override setSelected as follows: – (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; if(selected) { //Add your custom view to self… } else { //Remove your custom view… } } Boom, job done.
Unfortunately, there’s no such function provided in the API, so you’ll have to write your own. This site gives several calculations involving latitude/longitude and sample JavaScript code. Specifically, the section titled “Destination point given distance and bearing from start point” shows how to calculate what you’re asking. The JavaScript code is at the bottom of … Read more
The following viewDidLoad will (1) set two locations, (2) remove all the previous annotations, and (3) call user defined helper functions (to get route points and draw the route). -(void)viewDidLoad { [super viewDidLoad]; // Origin Location. CLLocationCoordinate2D loc1; loc1.latitude = 29.0167; loc1.longitude = 77.3833; Annotation *origin = [[Annotation alloc] initWithTitle:@”loc1″ subTitle:@”Home1″ andCoordinate:loc1]; [objMapView addAnnotation:origin]; // … Read more
I don’t know how exactly the bottom sheet of the new Maps app, responds to user interactions. But you can create a custom view that looks like the one in the screenshots and add it to the main view. I assume you know how to: 1- create view controllers either by storyboards or using xib … Read more
The problem there is that you are using URL property absoluteString where you should be using the path property. The difference between absoluteString and path properties is that absoluteString includes the file url scheme (“file://”) which is the reason it doesn’t find the file at what was supposed to be its path but it is … Read more
