objective c - Either AppDelgate is called or ViewController is -

i wanting both appdelegate , viewcontroller called on startup (as expected).

when viewcontroller called:

main.c

int main(int argc, const char * argv[]) {     return nsapplicationmain(argc, argv); } 

when appdelegate called , view controller not.

main.c

#import "appdelegate.h"  int main(int argc, const char *argv[]) {     nsarray *tl;     nsapplication *application = [nsapplication sharedapplication];     [[nsbundle mainbundle] loadnibnamed:@"viewcontroller" owner:application toplevelobjects:&tl];      appdelegate *applicationdelegate = [[appdelegate alloc] init];      // instantiate app  delegate     [application setdelegate:applicationdelegate];                      // assign delegate nsapplication     [application run];                                                  // call apps run method      return 0;       // app never gets here. } 

i think problem second attempt of main.c that...

nsapplication *application = [nsapplication sharedapplication];         [[nsbundle mainbundle] loadnibnamed:@"viewcontroller" owner:application toplevelobjects:&tl]; 

is not working expected. set 'nib' in ib?

what wrong?

you've got kind of confused.... should more closely @ other answer on here: other answer

your first main.c example wrong. second main.c, closer example gave better, you're calling viewcontroller should referencing mainmenu nib, in example.

this line wrong:

 [[nsbundle mainbundle] loadnibnamed:@"viewcontroller" owner:application toplevelobjects:&tl]; 

put nib name there... that's why method argument called "loadnibnamed" :)- , rid of @"viewcontroller".

now if trying call full blown nib, don't need example. designed people trying programmatic.
