Xcode obj - C: I can't retrieve variable from another class's instance variable

In my WhatToEditViewController, I created an NSString property called whattoedit. When the user presses a certain button, whattoedit gets assigned to a string.

@interface WhatToEditViewController : UIViewController

@property (nonatomic, strong) NSString * whattoedit;

@end

#import "WhatToEditViewController.h"

implementation:

@implementation WhatToEditViewController

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)TappedMorning:(id)sender {
self.whattoedit = @"Morning";

}
- (IBAction)TappedAfternoon:(id)sender {

self.whattoedit = @"Afternoon";
}
- (IBAction)TappedEvening:(id)sender {

self.whattoedit = @"Evening";

}

(I checked this part of my program works :/) Also when the user presses the button, a new view controller called SettingsTableViewController gets pushed in. What I want to do is set the title of the navigation bar of SettingsTableViewController as WhatToEditViewController's whattoedit property.

Here is SettingsTableViewController's implementation:

#import "SettingsTableViewController.h"
#import "WhatToEditViewController.h"

@interface SettingsTableViewController ()

@end

@implementation SettingsTableViewController



- (void)viewDidLoad {
[super viewDidLoad];

WhatToEditViewController * editMode = [[WhatToEditViewController alloc] init];

self.navigationController.navigationBar.topItem.title = editMode.whattoedit;

Oddly, the navigation bar title turns into (null). Should the navigationBar.title code be in the viewdidload?

Thanks, Fez
