Question

在我的代码中，在点击TopBar上的nextbutton和backButton时，不会调用playerPlayBackDidFinish。但是当完整播放视频文件时会调用它，如果有人知道请帮助...

我的代码如下。

#import "seq_nineViewController.h"

@implementation seq_nineViewController

@synthesize ninethVideoController, Bean;
@synthesize localBackFlag;
@synthesize goingNextButton, goingBackButton;

    self.navigationController.navigationBarHidden = NO;
    self.navigationItem.hidesBackButton = YES;

    goingNextButton.title=@"Next";
    goingNextButton.target=self;
    goingNextButton.action=@selector(nextAction);
    self.navigationItem.rightBarButtonItem=goingNextButton;
    [goingNextButton release];

    goingBackButton =[[UIBarButtonItem alloc] init];
    goingBackButton.title=@"Back";
    goingBackButton.target=self;
    goingBackButton.action=@selector(backAction);

    self.Bean = [arr objectAtIndex:appDelegate.appLicationRowId];

    MediaVideoPostUIBean *seq9_asset = [[[self.Bean aplicationFlow] arrayOfMediaVideoPostUI]objectAtIndex:2];

    if  ([[seq9_asset skip] isEqualToString:skipValueFalse]) {

        [url appendString:[appDelegate.rootBean RootFileLocation]];
        if (appDelegate.avatarFlag == 1)

        else if (appDelegate.avatarFlag == 2)
            [url appendString:[seq9_asset srcUrlFemale]];

你读过这个吗？

MPMoviePlayerPlaybackDidFinishNotification

通知观察者该电影   玩完了。受影响的电影   玩家存储在对象中   通知的参数。该   userInfo字典   通知包含   MPMoviePlayerPlaybackDidFinishReasonUserInfoKey   键，表示原因   播放完毕。这个通知   播放失败时也会发送   因为错误。

在案件中不发送此通知   电影播放器正在显示的位置   在全屏模式下，用户点按   完成按钮。在那种情况下，   完成按钮可以播放电影   播放器转出时暂停   全屏模式。如果你想   您可以在代码中检测到这种情况   应监控其他通知   如   MPMoviePlayerDidExitFullscreenNotification。

确保您没有做任何未发送此通知的内容

<强>观察

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(movieDidExitFullscreen:)
                                                 name:MPMoviePlayerDidExitFullscreenNotification
                                               object:nil];

并添加操作

- (IBAction) movieDidExitFullscreen:(NSNotification*)notification
    {
        NSLog(@"movieDidExitFullscreen");
        [self.moviePlayer stop];
        [self.moviePlayer setFullscreen:NO animated:NO];
        [self.moviePlayer.view removeFromSuperview];
    }

未调用MPMoviePlayerPlaybackDidFinishNotification
