Question

我的应用包含MKMapView，可将用户位置显示为蓝色子弹。

现在我创建了一个按钮（就像在普通的地图应用程序中一样）按下时应该将地图视图居中到用户位置，但我不知道该怎么做。

Answer 1

您可以将地图视图用户跟踪模式设置为MKUserTrackingModeFollow。它会自动在用户位置设置地图中心。

- (IBAction)centerMapOnUserButtonClicked:(id)sender {
    [self.mapView setUserTrackingMode:MKUserTrackingModeFollow animated:YES]; 
}

Answer 2

[self.mapView setCenterCoordinate:self.mapView.userLocation.coordinate animated:YES];

Answer 3

我今天刚刚解决这个问题。

可以将MKUserTrackingBarButtonItem按钮添加到工具栏以从iOS Maps应用程序复制功能。按下按钮时，它将打开和关闭跟踪。

- (void)viewDidLoad
{
    [super viewDidLoad];    
    MKUserTrackingBarButtonItem *buttonItem = [[MKUserTrackingBarButtonItem alloc] initWithMapView:self.map];
    self.navigationItem.rightBarButtonItem = buttonItem;
}

Answer 4

就是这样：

locationManager = [[CLLocationManager alloc] init];
        if ([CLLocationManager locationServicesEnabled])
        {
            locationManager.delegate = self;
            locationManager.desiredAccuracy = kCLLocationAccuracyBest;
            locationManager.distanceFilter = kCLDistanceFilterNone;
            [locationManager startUpdatingLocation];
        }
        location = [locationManager location];
        CLLocationCoordinate2D coordinate = [location coordinate];;
        MKCoordinateRegion region;
        region.center=coordinate;
        MKCoordinateSpan span;
        span.latitudeDelta=10.015; // Vary as you need the View for 
        span.longitudeDelta=10.015;
        region.span=span;
        [mapView setRegion:region];

        self.mapView.showsUserLocation = YES;

Answer 5

Swift 3解决方案

@IBAction func centerUserButton(_ sender: Any) {
    self.mapView.setCenter(self.mapView.userLocation.coordinate, animated: true)
}

按下按钮时，将MKMapView置于我的位置
