objective c - ios - property not found when using forwarded class -

i trying implement vuforiasdk in existing project , running problem: cannot access custom properties , methods of object subtype of uiview class. seems can use uiview properties , not own.

here's of code:

eaglview.h

#import "ar_eaglview.h"  #define kqcarmarkerscanned              @"qcarmarkerscanned"  @interface eaglview : ar_eaglview {  }  @property (nonatomic, retain) nsstring *myval;  - (id)blablawithframe:(cgrect)frame;  @end 

eaglview.mm

 #import "eaglview.h"  #import "teapot.h"  #import "texture.h"   #import <qcar/renderer.h>  #import <qcar/videobackgroundconfig.h>  #import "qcarutils.h"  ...    @implementation eaglview   - (id)blablawithframe:(cgrect)frame {      nslog(@"bla bla enters..");       return [self initwithframe:frame]; }  - (id)initwithframe:(cgrect)frame {      self = [super initwithframe:frame];       myval = @"initwithframe";       if (self)      {        ...       }      return self;  } 

arviewcontroller.h

#import <uikit/uikit.h> @class eaglview, qcarutils;  @interface arviewcontroller : uiviewcontroller { @public     iboutlet eaglview *arview;  // augmented reality view     cgsize arviewsize;          // required view size  @protected     qcarutils *qutils;          // qcar utils singleton class @private uiview *parentview;         // avoids unwanted interactions between uiviewcontroller , eaglview nsmutablearray* textures;   // teapot textures bool arvisible;             // state of visibility of view }   @property (nonatomic, retain) iboutlet eaglview *arview;  @property (nonatomic) cgsize arviewsize;   - (void) handlearviewrotation:(uiinterfaceorientation)interfaceorientation;  - (void)freeopenglesresources;   @end 

arviewcontroller.mm

#import <quartzcore/quartzcore.h>  #import "arviewcontroller.h" #import "qcarutils.h" #import "eaglview.h" #import "ar_eaglview.h" #import "texture.h"  @interface arviewcontroller () - (void) unloadviewdata; - (void) handlearviewrotation:(uiinterfaceorientation)interfaceorientation; @end  @implementation arviewcontroller  @synthesize arview; @synthesize arviewsize;  ...  - (void)loadview {      nslog(@"arvc: loadview");       cgrect viewbounds;      viewbounds.origin.x = 0;      viewbounds.origin.y = 0;      viewbounds.size.width = arviewsize.height;      viewbounds.size.height = arviewsize.width;      //arview = [[eaglview alloc] initwithframe: viewbounds]; // have replaced line      arview = [[eaglview alloc] blablawithframe:viewbounds]; // 1 - custom method - gives error "method blablawithframe not selector eaglview class"       parentview = [[uiview alloc] initwithframe: viewbounds];      [parentview addsubview:arview];      self.view = parentview;  }    - (void)viewdidload  {       nslog(@"arvc: viewdidload");        nslog(@"arview class = %@", [arview class]);        if (textures == nil)            textures=[qutils loadtextures:arview.texturelist]; // here occurs error saying texturelist property doesn't exists       [arview usetextures:textures];        [qutils createarofsize:arviewsize fordelegate:arview];       arvisible = no;   } 

.. , "unrecognized selector sent instance" error everytime try access property of arview object

i have tried (almost) everything... still have no idea what's causing it. if has clue of settings maybe set in project, please help!

thanks!
