MapKit always centers on userlocation - ios

Question

I have a map that zooms appropriately to the current location on load, but then doesn't allow you to pan around the map without it immediately zooming back in on the user location. I have been playing around with tracking mode but haven't gotten the right fix.. Here is some code, I appreciate the help.
- (void)viewDidLoad
{
[super viewDidLoad];
contentArray = [[NSMutableArray alloc] init];
mapViewuno.delegate = self;
mapViewuno.mapType = MKMapTypeStandard;
mapViewuno.userInteractionEnabled=YES;
locationManager = [[CLLocationManager alloc] init];
// Do any additional setup after loading the view, typically from a nib.
}
- (BOOL)prefersStatusBarHidden {
return YES;
}
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
self.navigationController.navigationBarHidden = YES;
indexValue = 0;
NSString* plistPath = [[NSBundle mainBundle] pathForResource:#"mapAddress" ofType:#"plist"];
NSMutableDictionary *dict = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
NSString *strID = [NSString stringWithFormat:#"%d",intID];
NSLog(#"array : %#",[dict objectForKey:strID]);
[contentArray removeAllObjects];
[contentArray addObjectsFromArray:[dict objectForKey:strID]];
[contentArray retain];
[self zoomToUserLocation:mapViewuno.userLocation];
}
- (void)zoomToUserLocation:(MKUserLocation *)userLocation
{
if (!userLocation)
return;
MKCoordinateRegion region;
region.center = userLocation.location.coordinate;
region.span = MKCoordinateSpanMake(.5, .5);
region = [mapViewuno regionThatFits:region];
[mapViewuno setRegion:region animated:YES];
counter = 0;
[mapViewuno removeAnnotations:mapViewuno.annotations];
if([contentArray count] != 0)
{
for(indexValue = 0; indexValue<[contentArray count];indexValue++)
{
FirstAnnotation *obj=[[FirstAnnotation alloc]init];
obj.latitude = [[[contentArray objectAtIndex:indexValue] objectForKey:#"lattitude"] floatValue];
obj.longitude = [[[contentArray objectAtIndex:indexValue] objectForKey:#"Longitude"] floatValue];
obj.titleName=[[contentArray objectAtIndex:indexValue] objectForKey:#"Title"];
obj.Address = [[contentArray objectAtIndex:indexValue] objectForKey:#"Address"];
obj.Phone = [[contentArray objectAtIndex:indexValue] objectForKey:#"Phone"];
obj.intTag = indexValue;
[mapViewuno addAnnotation:obj];
}
if ([mapViewuno.annotations count] == 0) return;
// [self.mapView setRegion:newRegion animated:YES];
}
}
-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
[self zoomToUserLocation:userLocation];
}

Answer 1

This part is causing the problem:
-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
[self zoomToUserLocation:userLocation];
}
Every time the mapview's location manager gets a new fix (i.e. every second or so) the mapview calls that delegate method which in turn calls your method to zoom. Put in a BOOL like zoomedToUserLocation and set it to NO at init time, then to YES when it hits zoomToUserLocation the first time.
