iPhone Dev - Is it possible to load an app's mainWindow conditionally?

Is it possible to code this sequence of events once an iPhone app has been launched?

• User launches application.
• AppDelegate.m checks if data is present in internal database.
• If yes, MainWindow.xib loads.
• If no, AnotherViewController.xib loads.

I've only seen app examples that load the MainWindow.xib without conditions.

If it is possible, which method in AppDelega开发者_C百科te.m handles the logic? (applicationDidFinishLaunching? viewDidLoad?)

I don't think you want to load the MainWindow conditionally. Instead, load and show a viewController conditionally. This can be done in applicationDidFinishLaunching.
