Is there like a default url scheme, like
openapp://Facebook, that would open the Facebook app (or whatever) if you click that URL from Safari on an iOS device? Or is there some other way to accomplish this?
And does the app have to be specially coded to handle this?
My company has an app but we don't have the budget right now to update it to handle any special URL schemes, but I'd really like a way to open it directly from a button on the web site.
