Question

I have decided to load my views programmatically, so putting:

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

Would not work. I do have a ViewController and an AppDelegate, though. What would be the proper use of UIApplicationMain to use a ViewController and an AppDelegate.
PS I am NOT using XCode or Interface Builder, I am developing on the toolchain.

Answer 1

This function is declared as

int UIApplicationMain (
   int argc,
   char *argv[],
   NSString *principalClassName,
   NSString *delegateClassName
);

Since you did not subclass UIApplication, pass nil to the 3rd argument. But you have a custom UIApplicationDelegate. So pass its class name to the 4th argument.

int retval = UIApplicationMain(argc, argv, nil, @"AppDelegate");
