Map reverting to user's location, not allowing 'browse' iOS - ios

Question

The map screen of the app displays the user's current location. I want to allow the user to 'browse' the map (scroll around and explore other areas) and I have a button which returns the user to the point on the map with their current location BUT I'm what's happening is that the app isn't allowing the user to 'browse' the map and retain the view they are looking at, rather it jumps right back to the user's current location.
Here is some code:
-(void) setupLocation {
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
// locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
[locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(#"didFailWithError: %#", error);
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
// [self.mapView setCenterCoordinate:self.mapView.userLocation.coordinate animated:YES];
tempLat = newLocation.coordinate.latitude;
tempLon = newLocation.coordinate.longitude;
CLLocationCoordinate2D currentLocation = CLLocationCoordinate2DMake(tempLat, tempLon);
MKCoordinateRegion viewRegionLocation = MKCoordinateRegionMakeWithDistance(currentLocation, 100, 100);
[self.mapView setRegion:viewRegionLocation animated:YES];
locationNew = [[CLLocation alloc] initWithLatitude:newLocation.coordinate.latitude longitude:newLocation.coordinate.longitude];
locationOld = [[CLLocation alloc] initWithLatitude:oldLocation.coordinate.latitude longitude:oldLocation.coordinate.longitude];
}
I also have:
- (IBAction)stopUpdating:(id)sender {
[locationManager stopUpdatingLocation];
}
And:
- (IBAction)findMe:(id)sender {
[locationManager startUpdatingLocation];
}
Any ideas of why the map keeps jumping back to the user's current location??
Thank you very much!

Answer 1

Because, in your - (void)locationManager: didUpdateToLocation: fromLocation: method you set the region of your mapview to the updated location everytime.
Removing this part will solve your problem.
MKCoordinateRegion viewRegionLocation = MKCoordinateRegionMakeWithDistance(currentLocation, 100, 100);
[self.mapView setRegion:viewRegionLocation animated:YES];
EDIT 1:
add this line in your viewDidLoad method,
self.mapView.showsUserLocation = YES;
change the find me button press method like this,
-(IBAction) findMeButtonPressed:(id)sender;{
MKCoordinateRegion viewRegionLocation = MKCoordinateRegionMakeWithDistance([self.locationManager location].coordinate, 100, 100);
[self.mapView setRegion:viewRegionLocation animated:YES];
}
