please me how this? badly searching it. thanks.

well, after long time search, found open source library ports uikit macosx.
https://github.com/bigzaphod/chameleon.git
it's complicated me, wrote own navigation controller.

nsnavigationcontroller.h

#import <cocoa/cocoa.h>  @class baseviewcontroller; @interface nsnavigationcontroller : nsresponder @property (nonatomic, strong) baseviewcontroller *rootviewcontroller;  - (id)initwithrootviewcontroller:(baseviewcontroller *)rootviewcontroller; - (nsview*)view;  - (void)pushviewcontroller:(baseviewcontroller *)viewcontroller animated:(bool)animated; - (baseviewcontroller *)popviewcontrolleranimated:(bool)animated; @end

nsnavigationcontroller.m

#import "nsnavigationcontroller.h" #import "appdelegate.h" #import "baseviewcontroller.h"  @interface nsnavigationcontroller () @property (nonatomic, strong) nsmutablearray *viewcontrollerstack; @end  @implementation nsnavigationcontroller - (id)initwithrootviewcontroller:(baseviewcontroller *)rootviewcontroller {     self = [super init];     if (self) {         self.rootviewcontroller = rootviewcontroller;         self.rootviewcontroller.navigationcontroller = self;         self.viewcontrollerstack = [[nsmutablearray alloc] initwithobjects:self.rootviewcontroller, nil];     }     return self; }  - (nsview*)view {     baseviewcontroller *topviewcontroller = [self.viewcontrollerstack objectatindex:[self.viewcontrollerstack count] - 1];     return topviewcontroller.view; }  - (void)pushviewcontroller:(baseviewcontroller *)viewcontroller animated:(bool)animated {     if (viewcontroller != nil) {         [self removetopview];         [self.viewcontrollerstack addobject:viewcontroller];         viewcontroller.navigationcontroller = self;         [self addtopview];     } }  - (baseviewcontroller *)popviewcontrolleranimated:(bool)animated {     baseviewcontroller *topviewcontroller = [self.viewcontrollerstack objectatindex:[self.viewcontrollerstack count] - 1];     [self removetopview];     [self.viewcontrollerstack removelastobject];     [self addtopview];      return topviewcontroller; }  - (void)removetopview {     baseviewcontroller *topviewcontroller = [self.viewcontrollerstack objectatindex:[self.viewcontrollerstack count] - 1];     [topviewcontroller.view removefromsuperview]; }  - (void)addtopview {     baseviewcontroller *topviewcontroller = [self.viewcontrollerstack objectatindex:[self.viewcontrollerstack count] - 1];     appdelegate *delegate = (appdelegate*)[nsapp delegate];     [delegate.window.contentview addsubview:topviewcontroller.view]; } @end

baseviewcontroller.h

#import <cocoa/cocoa.h>  @class nsnavigationcontroller;  @interface baseviewcontroller : nsviewcontroller @property (nonatomic, weak) nsnavigationcontroller *navigationcontroller; @end

baseviewcontroller.m

#import "baseviewcontroller.h"  @interface baseviewcontroller ()  @end  @implementation baseviewcontroller  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         // initialization code here.     }     return self; }  @end

it's simplest navigationcontroller. didn't implement view animation. hope can help.
