NSInvalidArgumentException "MPMoviePlayerController를 사용하여 인스턴스로 전송 된 인식 할 수없는 선택기"

Question

음, 단일 레코드의 정보를 표시하는 DetailViewController가있는 RootViewController에 TableView가 있습니다. 상세 페이지에서 나는 멀티미디어 파일을 재생하고 난 프레임 워크 MediaPlayer를 사용하고,이 설명서에 따르면 : 그것은 모든 확인을 보인다 http://www.techotopia.com/index.php/Video_Playback_from_within_an_iOS_4_iPhone_Application

,하지만 난 재생 버튼을 클릭 할 때이 오류가 :

[...] 

// Create a table view controller 
    RootViewController *rootViewController = [[RootViewController alloc] 
               initWithStyle:UITableViewStylePlain]; 

    rootViewController.managedObjectContext = context; 
    rootViewController.entityName = @"Porti"; 


    UINavigationController *aNavigationController = [[UINavigationController alloc] 
                initWithRootViewController:rootViewController]; 

    self.navigationController = aNavigationController; 


    UIBarButtonItem *homeButton; 
    homeButton = [[[UIBarButtonItem alloc] initWithTitle:@"    Inizio    " style:UIBarButtonItemStyleBordered target:self action:@selector(home)] autorelease]; 

    UIBarButtonItem *barButton; 
    barButton = [[[UIBarButtonItem alloc] initWithTitle:@"  Mappa dei porti  " style:UIBarButtonItemStyleBordered target:self action:@selector(caricamappa)] autorelease]; 

    [toolbar setItems:[NSArray arrayWithObjects: homeButton, barButton, nil]]; 


    [window addSubview:[navigationController view]]; 
    [window addSubview:toolbar]; 
    [window makeKeyAndVisible]; 

    [rootViewController release]; 
    [aNavigationController release]; 

:이 탐색 컨트롤러를 사용하는 AppDelegate에에서

:

-[DetailsViewController playmovie]: unrecognized selector sent to instance 0x9117f60 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[DetailsViewController playmovie]: unrecognized selector sent to instance 0x9117f60'

와 I는 DetailViewController에 전달하기 위해 명령어를 사용 RootViewController의 516,:

//Push the new table view on the stack 
    [self.navigationController pushViewController:detailsView animated:YES]; 
    [detailsView release]; 

DetailsViewController.h

#import <UIKit/UIKit.h> 
#import <MessageUI/MessageUI.h> 
#import "MLUtils.h" 
#import <MediaPlayer/MediaPlayer.h> 

@interface DetailsViewController : UIViewController {

제 질문은 : 내 오류는 어디에 있습니까? 나는 그것이 playmovie 메서드의 호출에 있다고 상상하지만 솔루션을 알아낼 수는 없습니다!

P.
실수로 댓글을 삭제했습니다. 너무 죄송합니다. = (

Answer 1

당신은 클래스가 아닌 객체에 playmovie를 호출하거나 PARAM을 제공하는 것을 잊지 것 같다. 당신은 당신이 전화를 우리에게 보여 주면, 그 도움이됐다.

어쨌든, 문제가 당신은 아마 할 것을 :

[DetailsViewController playmovie]; 

또는

[oneDetailsViewController playmovie]; 

대신

:

[oneDetailsViewController playmovie:nil]; 

여기서 oneDetailsViewController은 DetailsViewController* 개체입니다.
