UIView not appearing

So I have this code -

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
    self.searchController = [[PlacesViewController alloc]initWithNibName:@"PlacesView" bundle:nil];
    NSLog(@"TEXT FIELD DID BEGIN EDITIN");
    self.navigationItem.hidesBackButton = YES;
    [self.navigationController pushViewController:self.searchController animated:YES];
    return NO;
}

The NSLog runs, but my view doesn't appear. This is happening in a controller that has a view that exists in the navigation bar. Like this -

-(void)addSearchBar{
    self.searchBarController = [[SearchBarController alloc] initWithNibName: @"SearchBar" bundle: nil];
    self.navigationItem.titleView = self.searchBarController.view;
}

where addSearchBar is called in the initWithNibName method.

Why is my view not appearing? 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        searchQuery = [[SPGooglePlacesAutocompleteQuery alloc] init];
        searchDetailQuery = [[SPGooglePlacesPlaceDetailQuery alloc] init];
        searchQuery.radius = 2000;
        shouldBeginEditing = YES;
        locationManager = [[CLLocationManager alloc] init];
        locationManager.delegate = self;
        locationManager.distanceFilter = kCLDistanceFilterNone;
        locationManager.desiredAccuracy = kCLLocationAccuracyBest;
        [locationManager startUpdatingLocation];

    }
    return self;
}

I've also proven that the view works because when I do this -

-(void)textFieldDidBeginEditing:(UITextField *)textField{
    self.searchController = [[PlacesViewController alloc]initWithNibName:@"PlacesView" bundle:nil];
    //may have to be strong.
    NSLog(@"SELF VIEW : %@", self.view);
    textField.inputView.center = self.view.center;
    textField.inputView.bounds = self.view.bounds;
    textField.inputView = self.searchController.view;
}

The view appears in place of the keyboard.

You can move the addSearchBar from initWithNibName to viewDidLoad for a try. In fact, usually in the init method, the view doesn't initialize. The view will be lazily initialize when it is first access, usually when you show the view on the screen, and the viewDidLoad method will be call immediately after the view is initialized. So usually the init method only configure data related property, and the view related property usually configured in the viewDidLoad method.
