uitableview - 点击单元格时如何播放视频？

Question

我想在点击第一个单元格时打开一个视频，我想在我点击第二个单元格时打开另一个视频，依此类推。

有人可以告诉我我该怎么做吗？我有这个代码。

  - (NSInteger)tableView:(UITableView *)tableView
 numberOfRowsInSection:(NSInteger)section
{
    return 3;//[array count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = 
    [tableView dequeueReusableCellWithIdentifier:@"cell"];

    // create a cell
    if ( cell == nil)
    {
        cell = [[UITableViewCell alloc]
                initWithStyle:UITableViewCellStyleSubtitle
                reuseIdentifier:@"cell"];
    }

    //retrieve an image/ Zet een afbeelding naast de titel
    NSString *imagefile = [[NSBundle mainBundle]
                           pathForResource:@"cellimage" ofType:@"png"];
    UIImage *ui = [[UIImage alloc] initWithContentsOfFile:imagefile];
    //set the image on the table cell/ zet hem in de tabel
    cell.imageView.image = ui;


    //set the main text/hoofd tekst
    cell.textLabel.text = [exercises objectAtIndex:indexPath.row];

    //set the subtitle text/ ondertekst
    cell.detailTextLabel.text = @"Management training", @"Ondertiteling hier", @"Ondertiteling hier";



    //accessory type /zijn de navigatie pijltjes, er zijn 3 verschillende 
    cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;

    //return the cell
    //cell.textLabel.text = [array objectAtIndex:indexPath.row];
    return cell;
}

/*
 // The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        // Custom initialization
    }
    return self;
}
*/


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
    exercises = [[NSArray alloc]
                 initWithObjects:@"BAZO", @"Ontslag gesprek",
                 @"Management training",nil];

    self.title = @"Training lijst";

    //Probeerzel
    /*array = [[NSMutableArray alloc] init];
    [array addObject:@"Bazo"];
    [array addObject:@"secondmovie"];*/


    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

我知道它有很多代码，但这是表格的代码。

我已经导入了 MediaPlayer.framework。但我不知道如何将单元格链接到视频。

感谢您的宝贵时间!

您还需要将 View Controller 设置为 TableView 的委托(delegate)，并在 View Controller 中实现 -[UITableViewDelegate tableView:didSelectRowAtIndexPath:] 委托(delegate)方法。当用户点击您的表格单元格之一时，将调用此方法。

在 tableView:didSelectRowAtIndexPath: 的实现中，您将设置一个 MPMoviePlayerController 来播放您的电影，如下所示:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // First, get the URL for the video file you want to play.  For example, if you have an array of the movie file URLs, you'd do this:
    NSURL * movieURL = [_movieFileURLs objectAtIndex:indexPath.row];

    // Now set up the movie player controller and play the movie.
    MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL: movieURL];
    [[player view] setFrame: [self.view bounds]];  // frame must match parent view
    [self.view addSubview: [player view]];
    [player play];
}
