ios google maps delegate events not firing in simulator - ios

Question

For some reason, I can't seem to get tap and longtap and all the other delegate events to work in my simulator. I think I installed everything correctly because the map shows up on the screen, with a custom button click I can put a marker on the map, but it will not recognize the delegate events. Am I doing something wrong???
mapviewcontroller.h
#import <UIKit/UIKit.h>
#import <GoogleMaps/GoogleMaps.h>
#import <CoreLocation/CoreLocation.h>
#interface MapViewController : UIViewController <GMSMapViewDelegate, CLLocationManagerDelegate>
#property (weak, nonatomic) IBOutlet UIView *mapContainer;
- (IBAction)addmarker:(id)sender;
#end
mapviewcontroller.m
#import "MapViewController.h"
#interface MapViewController ()
#end
#implementation MapViewController{
GMSMapView *mapView;
}
#synthesize mapContainer;
- (void)viewDidLoad
{
[super viewDidLoad];
mapView.delegate = self;
mapView.myLocationEnabled = YES;
mapView.settings.myLocationButton = YES;
mapView.settings.compassButton = YES;
//CLLocation *myLoc = mapView.myLocation;
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86 longitude:151.20 zoom:15];
mapView = [GMSMapView mapWithFrame:CGRectMake(0, 0, self.mapContainer.frame.size.width, self.mapContainer.frame.size.height) camera:camera];
[self.mapContainer addSubview:mapView];
}
- (void) mapView: (GMSMapView *) mapView didTapAtCoordinate: (CLLocationCoordinate2D) coordinate{
NSLog(#"%f, %f", coordinate.latitude, coordinate.longitude);
}
- (void) mapView:(GMSMapView *)mapView didLongPressAtCoordinate:(CLLocationCoordinate2D)coordinate{
NSLog(#"tapped");
}
- (void) mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker{
NSLog(#"tapped info");
}
- (void) mapView:(GMSMapView *)mapView didBeginDraggingMarker:(GMSMarker *)marker{
NSLog(#"dragged");
}
- (IBAction)addmarker:(id)sender {
CLLocationCoordinate2D position = CLLocationCoordinate2DMake(-33.86, 151.20);
GMSMarker *marker = [GMSMarker markerWithPosition:position];
marker.title = #"hello";
marker.map = mapView;
}
#end
The only thing that works is the IBAction. Also my location and compass buttons do not show up. Any ideas of why it's not working? I declared the delegates...

You need to set all properties after the object initialization.
- (void)viewDidLoad {
[super viewDidLoad];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86 longitude:151.20 zoom:15];
mapView = [GMSMapView mapWithFrame:CGRectMake(0, 0, self.mapContainer.frame.size.width, self.mapContainer.frame.size.height) camera:camera];
mapView.delegate = self;
mapView.myLocationEnabled = YES;
mapView.settings.myLocationButton = YES;
mapView.settings.compassButton = YES;
[self.mapContainer addSubview:mapView];
}
