Question

I’ve been reading about pros/cons of programming with/without an interface builder and i want to try writing an app from scratch. however, even with a window based application it creates a xib file and i would like to remove this but not sure what to do after. just really need that jump start. Thanks!

Fundamentally you have to specify the appDelegate in UIApplicationMain() (in main.m), that is… from:

int retVal = UIApplicationMain(argc, argv, nil, nil);

to:

int retVal = UIApplicationMain(argc, argv, nil, @"MyAppDelegate");

then in MyAppDelegate’s method application:didFinishLaunchingWithOptions: you have to manually create your UI:

// initialize application's window
_window = [[UIWindow alloc] initWithFrame:MAIN_FRAME];

// activate and display application's window
[_window makeKeyAndVisible];

…and so on
