Different data for sharing providers in UIActivityViewController

Question

I\'m trying to use an UIActivityViewController with one long NSString as the data. If I put a string > 140 characters, the tweet sheet in it does n

Answer 1

This can be easily done by using the optional activityType property from the UIActivityItemProvider object. That property returns a UIActivityType, so you can do something like:

class PhotoActivityItemProvider: UIActivityItemProvider {  
    ...

    override var item: Any {
        guard let activityType = self.activityType else {
            return photoURL.absoluteString
        }
        if activityType == .mail || activityType == .message {
            return "The photo link is \(photoURL.absoluteString)."
        }

        ...
    }
