本文介绍如何在iOS应用程序中使用AVFoundation框架播放本地存储的MP4视频文件。通过创建AVPlayer实例并将其与UIView关联，实现视频的加载与播放。

#import "ViewController.h"
#import <QuartzCore/QuartzCore.h>
#import <AVFoundation/AVFoundation.h>

@interface ViewController ()

@property (nonatomic, weak) IBOutlet UIView *containerView; @end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    //get video URL
    NSURL *URL = [[NSBundle mainBundle] URLForResource:@"Ship" withExtension:@"mp4"];

    //create player and player layer
    AVPlayer *player = [AVPlayer playerWithURL:URL];
    AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];

    //set player layer frame and attach it to our view
    playerLayer.frame = self.containerView.bounds;
    [self.containerView.layer addSublayer:playerLayer];

    //play the video
    [player play];
}
@end
