Would anyone be able to show me how to add a
@property (nonatomic, strong) IBOutlet MKUserTrackingBarButtonItem *trackingButton;
trackingButton = [[MKUserTrackingBarButtonItem alloc] initWithMapView:mapView];
NSMutableArray *items = [[NSMutableArray alloc] initWithArray:toolbar.items];
[items insertObject:trackingButton atIndex:0];
Unfortunately this doesn't seem possible in IB due to the designated initializer of
MKUserTrackingBarButtonItem. You have to instantiate it and add it to the toolbar programmatically, as you are doing.
