iPhone: Detecting Tap in MKMapView

Question

How do I detect a single tap on an instance of MKMapView? Do I have to subclass MKMapView and then override the touchesEnded method?

Answer 1

my 2 cents for swit 5.x:

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
    if let touch = touches.first {
        let v = touch.view
        let ssv = v?.superview?.superview
        if ssv === self.mapView{
            searchBar.resignFirstResponder()
        }
    }
}

it works. but honestly can break if apple changes layers of views. better a recognizer.

Answer 2

Just add some code snippet as illustration of @tt-kilew answer. In my case, I want to point the user to itself on the map but do not want to interrupt his drag touch.

@interface PrettyViewController () <MKMapViewDelegate>

@property (weak, nonatomic) IBOutlet MKMapView *mapView;
@property (assign, nonatomic) BOOL userTouchTheMap;

@end

@implementation PrettyViewController

#pragma mark - UIResponder

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];

    self.userTouchTheMap = [[touches anyObject].view isEqual:self.mapView];
}


#pragma mark - MKMapViewDelegate

- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {
    //We just positioning to user
    if (!self.userTouchTheMap) {
        CLLocationDistance radius = 5000;
        [self.mapView setRegion:MKCoordinateRegionMakeWithDistance(userLocation.location.coordinate, 2*radius, 2*radius) animated:YES];
    }
}

@end
