In Java one can specify the class what class is called when program starts. It must have public static void main .. you know the drill.

How about in Objective-C? Of all the classes you may have present in your program which one is called first?

    The starting point is not in a class but in the main function, same as regular C:

    int main( int argc, const char *argv[] )

    For an iOS app, this is generally generated for you and control is passed into your UIApplicationMain.

    For more information, see the section on the main function in the docs here.
