I've been looking for an equivalent Swift code sample for Facebook friend invite for iOS apps. But I can't find them.
I understand that there is the Objective-C version on Facebook page https://developers.facebook.com/docs/app-invites/ios. However, because I started off with Swift, I find it difficult to translate.
Could someone point me to a source? Thank you.
the code working :
-In viewDidLoad :
let content = FBSDKAppInviteContent()
content.appLinkURL = NSURL(string: "https://test/myapplink")
content.appInvitePreviewImageURL = NSURL(string: "https://test/myapplink")
// Old Way, now depreciated :
//FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self)
//New way :
FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self)
// Do any additional setup after loading the view.
-In your viewController to conform the protocol delegate:
extension InviteFriendsViewController: FBSDKAppInviteDialogDelegate{
func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) {
//TODO
}
func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) {
//TODO
}
}
Facebook Friend invite in Swift 3.0
First of all, import FBSDKCoreKit, FBSDKShareKit and add delegate FBSDKAppInviteDialogDelegate. Then, on invite friend button click, add the code below:
let inviteDialog:FBSDKAppInviteDialog = FBSDKAppInviteDialog()
if(inviteDialog.canShow()){
let appLinkUrl:NSURL = NSURL(string: "http://yourwebpage.com")!
let previewImageUrl:NSURL = NSURL(string: "http://yourwebpage.com/preview-image.png")!
let inviteContent:FBSDKAppInviteContent = FBSDKAppInviteContent()
inviteContent.appLinkURL = appLinkUrl as URL!
inviteContent.appInvitePreviewImageURL = previewImageUrl as URL!
inviteDialog.content = inviteContent
inviteDialog.delegate = self
inviteDialog.show()
}
Then, add the methods below of FBSDKAppInviteDialogDelegate:
func appInviteDialog (_ appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [AnyHashable : Any]!) {
let resultObject = NSDictionary(dictionary: results)
if let didCancel = resultObject.value(forKey: "completionGesture")
{
if (didCancel as AnyObject).caseInsensitiveCompare("Cancel") == ComparisonResult.orderedSame
{
print("User Canceled invitation dialog")
}
}
}
func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: Error!) {
print("Error tool place in appInviteDialog \(error)")
}
Benobab solution is perfect, i just want to to add that in my case trying to run FBSDKAppInviteDialog.showFromViewController on viewDidAppear worked better.
