I am trying to follow this tutorial link, but i have issues. Can somebody please have a look and let me know what needs to be changed. I tried to looking up other examples but none seems to work. Please let me know what needs to be changed.

以下是错误

架构i386的未定义符号：
_ OBJC_CLASS _ $ _ MPMoviePlayerController，引用自：
objc-class-ref在VideoScreenViewController.o
_MPMoviePlayerPlaybackDidFinishNotification中，引自：
- VideoScreenViewController中的[VideoScreenViewController playVideo：] .o
- VideoScreenViewController.o中的[VideoScreenViewController moviePlayBackDidFinish：]
ld：找不到架构i386的符号
clang：错误：链接器命令失败，退出代码为1（使用-v看到调用）

Undefined symbols for architecture i386: "_OBJC_CLASS_$_MPMoviePlayerController", referenced from: objc-class-ref in VideoScreenViewController.o "_MPMoviePlayerPlaybackDidFinishNotification", referenced from: -[VideoScreenViewController playVideo:] in VideoScreenViewController.o -[VideoScreenViewController moviePlayBackDidFinish:] in VideoScreenViewController.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

这是代码

//  VideoScreenViewController.h

#import <UIKit/UIKit.h>
#import "MediaPlayer/MediaPlayer.h"
@interface VideoScreenViewController : UIViewController

@property (strong, nonatomic) MPMoviePlayerController *moviePlayer;

- (IBAction)playVideo:(id)sender;

@end

    }


#import "VideoScreenViewController.h"
#import "MediaPlayer/MediaPlayer.h"
@interface VideoScreenViewController ()

@end

@implementation VideoScreenViewController

@synthesize moviePlayer;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

    }
    return self;
}

}

        moviePlayer =  [[MPMoviePlayerController alloc]

                                                   object:moviePlayer];

        moviePlayer.controlStyle = MPMovieControlStyleDefault;
        moviePlayer.shouldAutoplay = YES;
        [self.view addSubview:moviePlayer.view];

}


- (void) moviePlayBackDidFinish:(NSNotification*)notification {

    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                         pathForResource:@"Movie" ofType:@"MOV"]];
    MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url];
    [[NSNotificationCenter defaultCenter] 
     removeObserver:self
     name:MPMoviePlayerPlaybackDidFinishNotification
     object:player];

    if ([player
         respondsToSelector:@selector(setFullscreen:animated:)])
    {
        [player.view removeFromSuperview];
    }
}
