This is it :

<pre><code>locationManager = [[CLLocationManager alloc] init];
 if ([CLLocationManager locationServicesEnabled])
 {
 locationManager.delegate = self;
 locationManager.desiredAccuracy = kCLLocationAccuracyBest;
 locationManager.distanceFilter = kCLDistanceFilterNone;

 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;
</code></pre>

You could just set map view user tracking mode to MKUserTrackingModeFollow. It would automatically set map center on user location.

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

I've just been working on this problem today. 

It's possible to add a MKUserTrackingBarButtonItem button to a toolbar to copy the functionality from the iOS Maps app. When pushing the button it will turn tracking on and off.

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

Swift 3 Solution

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

My app includes an <code>MKMapView</code> that shows the users location as a blue bullet.

Now I made a button (just like in a normal map app) that when pressed should center the map view onto the users location, but I don't know how to do so.

我的应用程序包括一个MKMapView，它以蓝色项目符号显示用户的位置。现在我做了一个按钮(就像一个普通的地图应用程序一样)，当按下这个按钮时，地图视图应该居中显示在用户的位置上，但是我不知道怎么做。
