Question

My code was working fine for days and weeks of code changes and running on my iPhone 5.0 simulator until I cleaned it.

Now it dies on this line [window addSubview:self.viewController.view];

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

    [self.window addSubview:self.viewController.view];   // dies here
    [self.window makeKeyAndVisible];

    return YES;
}

self.viewController exists, but self.viewController.view does not.

EDIT to add my AppDelegate.h:

#import <UIKit/UIKit.h>

@class MainMenu;

@interface yomikakiAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    MainMenu *viewController;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet MainMenu *viewController;

@end

I think IB must have lost a connection somewhere, but I’m not sure how to rewire it.

I made my MainMenu.xib Referencing Outlet view be File’s Owner, but that didn’t fix it.

How can I get my viewController get its view back?

Hello why are you doing this?

[window addSubview:self.viewController.view];

Try this

[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];
return YES;

The File Owner has to be linked to the View of the ViewController.
