@artur that could be cuz of two reasons. Either the simulator does not contain whatsapp, or your code is not passing the expected message to the whatsapp share extension
Or that your canOpenUrl function is not working for which you would have to add this to you info.plist file:
"<''key''>LSApplicationQueriesSchemes<''/key>
<''array>
<''string>whatsapp<''/string>
<''/array>
<''/dict>"
Hi, Sir,
I found few app now can share both image + text, do you have any idea how to implement. I can do only image (by UIdocumentInteractionController) or only text. Appreciate if you can teach me how to share photo + text to whatsapp.
Thanks in advanced.
This is not how it's supposed to be done. You should only store the URL in prepareWithActivityItems and open it in performActivity.
See the docs on prepareWithActivityItems:
Subclasses should override this method and use it to store a reference to the data items in the activityItems parameter.
https://developer.apple.com/reference/uikit/uiactivity/1620668-preparewithactivityitems
its not working for swift 4
When running in the simulator generates an error: fatal error: unexpectedly found nil while unwrapping an Optional value. And highlights the line of code: return NSURL(string: url)! . How to fix this error? The question that you have explained above, I do not understand where to enter your code. Thank you
