我是 XCode 的新手，并且在 Storyboard 中构建了一个 UITableView。第一个 UITableViewCell 有一个按钮，当按下它时，应该加载一个 .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......但我肯定错过了一个步骤，因为当我在 IOS Simulator 中选择按钮时出现以下错误：
" * 由于未捕获的异常 'NSInvalidArgumentException' 导致应用程序终止，原因：'* -[NSURL initFileURLWithPath:]: nil string parameter'"
我也有这个警告：“依赖分析警告：警告：没有规则来处理架构 i386 的文件类型文件'/Users/../my_mov1.mp4'
这是我在 TableViewController 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];
}

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

{
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.

// self.navigationItem.rightBarButtonItem = self.editButtonItem;

有什么我（肯定）想念的想法吗？
谢谢！
