【问题描述】：

我尝试将我照片库中选定视频中的视频分享到 Instagram 故事

func shareToInstagramStories(video: NSData) 
            // NOTE: you need a different custom URL scheme for Stories, instagram-stories, add it to your Info.plist!
            guard let instagramUrl = URL(string: "instagram-stories://share") else 
                return
            

            if UIApplication.shared.canOpenURL(instagramUrl) 
                let pasterboardItems = [["com.instagram.sharedSticker.backgroundVideo": video as Any]]
                UIPasteboard.general.setItems(pasterboardItems)
                UIApplication.shared.open(instagramUrl)
             else 
                //fail
            
    

这是我的图像选择器功能

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) 
        
        self.dismiss(animated: true, completion: nil)
        videoURL = info[UIImagePickerController.InfoKey.init(rawValue: "UIImagePickerControllerReferenceURL")] as? NSURL
     

【问题讨论】：

referenceURL 已弃用。顺便说一句，对于 ios 14 或更高版本，您应该使用 phpickerViewController

【参考方案1】：

当我将“UIImagePickerControllerReferenceURL”更改为“UIImagePickerControllerMediaURL”时，它完全起作用了

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) 
        self.dismiss(animated: true, completion: nil)
        videoURL = info[UIImagePickerController.InfoKey.init(rawValue: "UIImagePickerControllerMediaURL")] as? URL
