Opening Facebook event pages in the Facebook app using Swift

I am having a problem getting Facebook events in the Facebook app. For example, to open an event with the url "https://www.facebook.com/events/1743847059178738/," I would use the following code:

let facebookURL = NSURL(string: "fb://event/1743847059178738")!
if UIApplication.sharedApplication().canOpenURL(facebookURL) {
UIApplication.sharedApplication().openURL(facebookURL)
} else {
UIApplication.sharedApplication().openURL(NSURL(string: "https://www.facebook.com/events/1743847059178738")!)
}
}


It will open the Facebook app, but no matter what event I attempt to display I get a screen saying "Unable to load event. It may have been cancelled." I have tried substituting the Facebook URL of an event for that of a profile (e.g., string: "fb://profile/100005906912309") and it works just fine. Am I mistaken in assuming that the numbers at the end of the event's URL are the same as the event's numeric ID?

Answer

So I figured out that I could bypass the whole "fb://event..." bit and just go with:

UIApplication.sharedApplication().openURL(NSURL(string: "https://www.facebook.com/events/1743847059178738")!)

I assumed this would open the link in Safari, but it automatically opened in Facebook in iOS 8.
