Reproducible Demo



From my findings this is a bug of UIActivityViewController in iOS 11:

Changing the implementation in RCTActionSheetManager.m slightly seems to solve this issue:

Replace [items addObject:URL]; with [items addObject:URL.absoluteString];

solves the issue. For me sharing to other apps (e.g. Facebook) still works. Another option would be to add iOS version checks here or to wait for Apple to fix this problem (might only take some years).

I'm more than happy to provide this little change as a PR.

Go to the App Store and share an app via copy. You will see it's a iOS bug.

@ethanneff I totally agree.

Sadly users won't get this and blame the app itself. Therefor I was asking if this project is willing to accept a workaround für iOS 11?

It seems only happened in Apple's apps such as SMS and Note

If the workaround works and doesn't break any other use cases I think this is fine. Just make sure iOS still detects the URL and it is clickable.

Feel free to open a PR and document the fix since it is a bit of a workaround.
