You can link this IBAction to your UIButton, it's going to move the map on the current location and zoom on it.

您可以将此IBAction链接到您的UIButton,它将在当前位置移动地图并放大它。

@IBOutlet weak var mapView: MKMapView!

@IBAction func zoomToUserCurrentLocation(sender: AnyObject) {
    if self.mapView != nil {
        self.mapView.setRegion(MKCoordinateRegionMake(
            self.mapView.userLocation.coordinate, 
            MKCoordinateSpanMake(0.1, 0.1)
        ), animated: true)
    }
}

MKCoordinateSpan defines the area spanned by a map region, smaller these values are, closer you zoom on the map.

MKCoordinateSpan定义了地图区域所跨越的区域,这些值越小,越接近地图。

- (void)showCurrentLocation{

    MKMapPoint annotatiOnPoint= MKMapPointForCoordinate(self.mapView.userLocation.coordinate);
    MKMapRect zoomRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.0, 0.0);
    [self.mapView setVisibleMapRect:zoomRect animated:YES];
}
