Get the coordinates of a point from mkmapview on iphone

A bit of dead thread digging but as this is the top result in Google it may be worth it:

You can use the tap and hold gesture recognizer in order to get the coordinates and drop a pin on the map. Everything is explained at freshmob


You can try this code

- (void)viewDidLoad
{
    UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(foundTap:)];

    tapRecognizer.numberOfTapsRequired = 1;

    tapRecognizer.numberOfTouchesRequired = 1;

    [self.myMapView addGestureRecognizer:tapRecognizer];
}


-(IBAction)foundTap:(UITapGestureRecognizer *)recognizer
{
    CGPoint point = [recognizer locationInView:self.myMapView];  

    CLLocationCoordinate2D tapPoint = [self.myMapView convertPoint:point toCoordinateFromView:self.view];

    MKPointAnnotation *point1 = [[MKPointAnnotation alloc] init];

    point1.coordinate = tapPoint;

    [self.myMapView addAnnotation:point1];
}

All the best.


so i found a way to do it, finally. If i create a view and add a map object to it with the same frame. then listen for hit test on that view, i can call convertPoint:toCoordinateFromView: on the touch point sent, and give it the map like so:

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event{
    CLLocationCoordinate2D coord= [map convertPoint:point toCoordinateFromView:map];
    NSLog(@"lat  %f",coord.latitude);
    NSLog(@"long %f",coord.longitude);

    ... add annotation ...

    return [super hitTest:point withEvent:event];
}

this is pretty rough as is and as you scroll the map it still constantly calls hit test so you will need to handle that, but its a start at getting the gps coordinates from touching a map.
