Sprite kit 在SpriteKit SKVideoNode中播放来自摄影机滚轮的视频

我已经完成了大部分工作，但我仍然坚持做一些简单的事情。我正试图在SpriteKit中播放一段来自摄像机的视频。视频将从主捆绑包播放，视频选择器也会工作，直到我选择视频。我想我锁定了主线程，因为在选择视频时，选择器会冻结。非常感谢你的帮助

[viewController解除viewController激活：是完成：无]；
NSLog（“地点视频”）；

为其他想要此功能的人回答我自己的问题。必须在imagePicker方法中设置节点和播放机

- (void)getVideo {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
viewController = self.view.window.rootViewController;
[viewController presentViewController: imagePicker animated: YES completion:nil];

}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

fileURL = [info objectForKey:UIImagePickerControllerMediaURL];
[picker dismissViewControllerAnimated:YES completion:NULL];
player = [AVPlayer playerWithURL: fileURL];

videoNode1 = [[SKVideoNode alloc] initWithAVPlayer:player];
videoNode1.size = CGSizeMake(self.frame.size.width, self.frame.size.height);
videoNode1.position = CGPointMake(self.frame.size.width/2.0f, self.frame.size.height/2);
videoNode1.zPosition = 100.0f;
[self addChild:videoNode1];

player.volume = 1.0f;
[videoNode1 play];

 }
