Question

I have an application which loads a lot of data. I have the data loading on a separate thread, but while it loads I would like to show a splash screen. For the splash screen I created a NIB file, but I can’t get the NIB to display. I’m not really sure what I’m doing wrong. If anyone can help, I’d greatly appreciate it. Here is the code:

Header file:

@interface DigiWireCDAppDelegate : NSObject <UIApplicationDelegate> {
    --
    UIWindow *window;
    --
    UIView *loadingView;
    UIActivityIndicatorView *loadingAnimationIndicator;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
--
@property (nonatomic, retain) IBOutlet UIView *loadingView;
@property (nonatomic, retain) IBOutlet UIActivityIndicatorView *loadingAnimationIndicator;
--

Implementation:

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

    [self loadData];

    [loadingAnimationIndicator startAnimating];
    loadingView.hidden = NO;

    [window addSubview:loadingView];
    [window bringSubviewToFront:loadingView];

    [self.window makeKeyAndVisible];

    return YES;
}

In case this helps, here is the NIB:

Just because you have something set as an IBOutlet doesn’t mean the xib will load automatically. In your applicationDidFinishLaunching: you want to [[NSBundle mainBundle] loadNibNamed:@"loadingView" owner:self options:nil]; in order to actually load the xib into memory.
