如何从另一个ViewController播放AVPlayerView中的视频

Question

我在视图控制器中有一个AVPlayerView。我有另一个带有一个按钮(“播放视频”)的View Controller。我似乎不能让视频在这些视图控制器上播放。我在PlayTheVideo中添加了一个NSLog，当我按下按钮时，我看到视频仍然不能播放。我可以将代码行从PlayTheVideo移动到viewDidLoad，视频会立即播放，这样我就知道可以找到资源文件。我做错了什么？

//ViewController.h
@interface ViewController1 : NSViewController
@property (weak) IBOutlet AVPlayerView *VideoPlayer;
- (void)PlayTheVideo;

@end

//ViewController.m  
@implementation ViewController1
- (void)PlayTheVideo {
    NSURL* videoURL = [[NSBundle mainBundle] URLForResource:@"Clip 1" withExtension:@"mp4"];
    self.VideoPlayer.player = [AVPlayer playerWithURL:videoURL];
    [self.VideoPlayer.player play];
}
@end

//ViewController2.m
@implementation ViewController2
#import "ViewController.h"
- (IBAction)PlayVideo:(id)sender {
    ViewController1 *myClass = [[ViewController1 alloc] init];
    [myClass PlayTheVideo];
}
@end

Answer 1

NSURL* videoURL = [[NSBundle mainBundle] URLForResource:@"Clip1" withExtension:@"mp4"];
self.VideoPlayer.player = [AVPlayer playerWithURL:videoURL];
[self.VideoPlayer.player play];

在项目和代码中的文件name..so中都有一个空格，将文件名重命名为clip1。
