What I want to do is when I'm on map view and have got the user location I want to automatically zoom into the location. the h-file #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import <CoreLocation/CoreLocation.h> @interface WalkingTableViewController: UIViewController <MKMapViewDelegate> @property (weak,

问题 Can anyone suggest a good tutorial for implementing dragging feature for MKPinAnnotationView in iPhone MKMapView ? 回答1: you can find source code demo for MKPinAnnotationView Drag & drop feature from this link. Update: The Github project link given in above site url is not working. But I found new project example for that from this url. 回答2: To make an annotation draggable, set the annotation view's draggable property to YES. This is normally done in the viewForAnnotation delegate method so

问题 Am trying to add custom annotations on MKMapView and implement custom callOut view on tap of annotation. Am following this link for the same. The issue is when I add the custom annotation didSelectAnnotationView is called on its own and the popOver callout is shown, even when the user has not clicked the annotation Here is my code: -(void)callAddAnnotationsLocal{ [_mapView removeAnnotations:[_mapView annotations]]; CLLocationCoordinate2D coord = {.latitude = 43.3998170679, .longitude = -95

问题 I wrote this code to add a map view in a single page for my app. I want to add one more page with a different map view. How can I do this? controller.h # import < UIKit/UIKit.h > # import < MapKit/MapKit.h > @interface __3_ProductionsViewController : UIViewController { MKMapView *mapview; } @property (nonatomic, retain) IBOutlet MKMapView *mapview; -(IBAction)setMap:(id)sender; -(IBAction)getlocation; @end controller.m # import "__3_ProductionsViewController.h" # import " NewClass.h " #

问题 I am creating an iOS app using Parse database(asynchronously) to store information that will be used when populating a mapview. I have been trying to figure out what is wrong for a long time and have done plenty of research without any luck. I have, however, found the source of the issue. In my code, I am querying the parse database in hopes of getting the information I want and then storing the information in a custom pointAnnotation class, which is of type MkPointAnnotation. Each item is

问题 I have found a very wierd problem in MKMapView that i think might be a bug in the new xcode 4.2 and ARC (Automatic Reference Count). I created a very basic UIViewController class: MapViewController, that implements the protocol : #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import <CoreLocation/CoreLocation.h> @interface MapViewController : UIViewController <MKMapViewDelegate> @property (strong, nonatomic) IBOutlet MKMapView *mapView; I use a xib file to instantiate the mapview and link

问题 I have been programming for ios and I need to get address. How can I get full address from latitude and longitude in json or other format? Can I get it without internet connection? Thank you for your attention. 回答1: What you need is the CLGeocoder (on iOS 5) and MKReverseGeocoder (on older iOS versions). Both use Google Maps to get address data so you need an internet connection to get data. You'll get address as NSDictionary , but you can easily convert it to a JSON string with JSONKit or

问题 I have Some UIViews that are displayed over an MKMapView to serve as controls to filter the content of the map and my mapView have annotations that can show callout.I want to create an effect where my overlays will fade away if my callout appears or gets scrolled under the overlays and become visible again after the callout does not takes its place. Is there a way to find out if the Callout of an MKMapView is overlapping a UIView ? I have tried: Accessing frame of Callout to check if it

问题 I am building an iOS app and need to be able to place a pin where the user currently is! For some reason I have been having an awful time getting it to work! I tried the following code but was faced with an error. - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{ if (annotation == mapView.userLocation) { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:nil]; annView.pinColor =
