Question

I used the storyboard to create my application, where the initial View is an TabBarController.

But the first time the application starts I download the database (4Mb). So, my splash screen is displayed until the download is over, because the download is done in AppDelegate. I would like to change it and display a View to the user indicating that a download is being done, not to get the impression that the application crashed.

I tried this in didFinishLaunchingWithOptions: but doesn’t work:

LoadViewController *loadView = [[LoadViewController alloc] init];
[self.window makeKeyAndVisible];
[self.window addSubview:[loadView view]];

Thanks in advance.

I am not sure if this will meet your needs but I used MBProgressHUD to handle some display while uploading data to a server, maybe you could do something like the same with your download of the database.

HUD = [[MBProgressHUD alloc] initWithView:[self view]];
[[self view] addSubview:HUD];
HUD.dimBackground = YES;
HUD.delegate = self;
[HUD showWhileExecuting:@selector(taskToDownloadDatabase) onTarget:self withObject:nil animated:YES];

This would allow you to show the user some progress that something is happening and when the database is fully downloaded initialize your view.
