I'm trying to write a category for CLLocation to return the bearing to another CLLocation. I believe I'm doing something wrong with the formula (calculous is not my strong suit). The returned bearing is always off. I've been looking at this question and tried applying the changes that were accepted as a correct answer and the webpage i...
I am wanting to calculate total elevation loss and gain at the end of recording Core Location data. I am having a hard time thinking of the math for this one. Say if I started at 600 feet and I go up and down during the tracking, how would I calculate my elevation gain and loss? Ideas? ...
Indoors on an iPhone 4. WiFi disabled Running the LocateMe SDK sample or my own code for 30-60 seconds produces horizontal accuracy of 2294 meters. Pretty inaccurate but reasonable for cell tower triangulation. Looking at other apps that do reverse geocoding or location stuff like Foursquare shows a similar lack of accuracy. However, i...
I am making an iPhone app that is designed for things that will be local to only Missouri. So my idea is to limit the map to only Missouri/regions close to Missouri. I have the map working fine, displaying the user's location, and if they update location then the pin will also move. Can I use something like a Custom Annotation to do t...

Hi, I am writing an iPad application (os 3.2) which uses MKMapKit to display moving annotations on the map. Information is retrieved via XML from three different sources and collated together in my Annotation class and then displayed on the Map. This information is coming in every 5 seconds. I had this working fine for a few months w...
Hi, I have got a problem with a CLLocation. I wanted to know the distance between two coordinates to show it next to the title of the location in a tableView: static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewC...

When I don't try to implement the mapView:viewForAnnotation: method everything works (the annotation is added) but when I try to change the annotation view, the simulator crashes : Here is the code : MapViewController.h #import "MapViewController.h" #impor...
I was wondering if anyone knows of any subclasses for the MKAnnotationView class. On apples documentation they say one example is the MKPinAnnotationView so I was wondering if there were other pre-created subclasses like the one used to track the devices current location. If anyone has tips for creating my own subclass of the MKAnnotatio...

Hi all, I'm familiar with the Google Maps API and I'm trying to learned the iOS MapKit library now. I have an iPhone application which takes an input string and geocodes it using Google Maps geocoder service. I also want to set an appropriate zoom level for the new map but I'm not quite sure how to do it. After reading, http://stacko...
