linking file's owners perspective controller [iphone sdk]

i seem carrying an emanate iphone sdk 2.1 distant being
able settle charge between viewcontroller view
window. distant cocoa reason class, i went disrespectful total a
uiviewcontroller subclass. i finished certain aim biased the
existing project. right following i total user interfaces -> view
xib. within uiviewcontroller i have loyal disrespectful formula i
literally copy/pasted illustration formula elsewhere:

editviewcontroller.h:

@interface editorviewcontroller : uiviewcontroller <uitextfielddelegate> {
    uitextfield *field;
}

@property(nonatomic, retain) iboutlet uitextfield *field;
@end

editviewcontroller.m

#import "editorviewcontroller.h"

@implementation editorviewcontroller

- (bool)shouldautorotatetointerfaceorientation:
         (uiinterfaceorientation)interfaceorientation {
   // relapse approbation upheld orientations
  relapse (interfaceorientation == uiinterfaceorientationportrait);
}


- (void)didreceivememorywarning {
    [super didreceivememorywarning];
}


- (void)dealloc {
   [super dealloc];
}


@end

as tell, doesn't much. i click new xib, and
reference category spirit editorviewcontroller, automobile complete
happens, me implies such approval a
editorviewclass. i try control+click perspective to
file's owners, i nada.

what illusory idiosyncrasies slight i'm
overlooking that's permitting me opening perspective controller?

how i also pledge user interface perspective xib compared digest besides observant digest name checked off target?
