打开方式-iOS是否有类似功能？

Question

In Android I can for example open mp4 files in user's apps from my own app (using Intents). In the next example - intent for playing a video:

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(newVideoPath));
intent.setDataAndType(Uri.parse(newVideoPath), "video/mp4");
startActivity(intent);

Is there something similar for iOS? Can I open from my app for example url (of video) in Photos, VLC or another player (which are installed on iPhone/iPad)

if yes, any example in Swift ?

Answer 1

You should look at the documentation for Document interaction programming .

You can register file types that your app supports/can handle and then when a user selects a particular file from the files app or downloads from another app the system will offer a list of apps that can open this file, including yours.

Answer 2

UIActivityViewController might fit your needs.

For example,

let url = // URL to your .mp4 file
let activityVC = UIActivityViewController(activityItems: [url], applicationActivities: nil)
present(activityVC, animated: true, completion: nil)
