Question

I am programming a map app on iPhone and want the map to rotate as the user changes his direction. I have read most of the posts on stackoverflow. Most of them suggest the use of setUserTrackingMode with MKUserTrackingModeFollowWithHeading if we are working with iOS 5 or later. This does not seem to work with me for some reason. Following is my code:

-(IBAction)getLocation  //This is a button
{
    mapView.showsUserLocation=YES;  //mapView is the instance of MKMapView
    [mapView setUserTrackingMode:MKUserTrackingModeFollowWithHeading animated:YES];
}

This only shows the user location but if I move the phone, it doesn’t rotate.
One more thing is, I downloaded a project from internet, and I included this line. It worked there only for the first time. I have no idea why this is happening.

Any suggestions?

The easier way to do this is to include an MKUserTrackingBarButtonItem instead of creating your own button. It acts exactly the same as the button in the iOS 5 Maps app and is easy to set up.

Here’s how to use it:

// You should have an outlet to your map view called mapView
MKUserTrackingBarButtonItem *userTrackingButton;
userTrackingButton = [[MKUserTrackingBarButtonItem alloc] initWithMapView:self.mapView];

// You need an outlet to your toolbar too
[self.toolbar setItems:[NSArray arrayWithObject:userTrackingButton]];
