ios - 如何将 .mp4 添加到 uitableviewcell 中的按钮

Question

我是 XCode 的新手，在 Storyboard 中构建了一个 UITableView。第一个 UITableViewCell 有一个按钮，按下时应该加载 .mp4 全屏。我正在使用 MediaPlayerFramework 来实现这一点。

我的 .mp4 文件在项目中，它出现在 CopyBundleResources 中......但我肯定错过了一步，因为当我在 IOS 模拟器中选择按钮时出现以下错误:

“* 由于未捕获的异常‘NSInvalidArgumentException’而终止应用程序，原因:‘* -[NSURL initFileURLWithPath:]: nil string parameter’”

我也有这个警告:“依赖性分析警告:警告:没有规则来处理架构 i386 类型文件的文件‘/Users/../my_mov1.mp4’

这是我在 TableViewController 的子类中的代码:

RecipleTableViewController.h

@interface RecipleTableViewController : UITableViewController {


}

-(IBAction)playvideo;

@end

RecipleTableViewController.m

#import "RecipleTableViewController.h"
#import <MediaPlayer/MediaPlayer.h>

@interface RecipleTableViewController ()

@end

@implementation RecipleTableViewController

-(IBAction)playvideo {


    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"my_mov" ofType:@"mp4"]];
    MPMoviePlayerViewController *playercontroller = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
    [self presentMoviePlayerViewControllerAnimated:playercontroller];

    playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;

    [playercontroller.moviePlayer play];
}


- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Uncomment the following line to preserve selection between presentations.
    // self.clearsSelectionOnViewWillAppear = NO;

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

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1;
}

//- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
//{
#warning Incomplete method implementation.
    // Return the number of rows in the section.
 //   return 0;
//}

//- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
//{
  //  static NSString *CellIdentifier = @"Cell";
   // UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // Configure the cell...

    //return cell;
//}

/*
// Override to support conditional editing of the table view.
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Return NO if you do not want the specified item to be editable.
    return YES;
}
*/

/*
// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source
        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }   
    else if (editingStyle == UITableViewCellEditingStyleInsert) {
        // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
    }   
}
*/

/*
// Override to support rearranging the table view.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
}
*/

/*
// Override to support conditional rearranging of the table view.
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Return NO if you do not want the item to be re-orderable.
    return YES;
}
*/

/*
#pragma mark - Navigation

// In a story board-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}

 */

知道我(肯定)遗漏了什么吗？

谢谢!

您正在尝试获取 my_mov 的 URL，而实际文件名似乎是 my_mov1。
