and here is my facebook and twitter actionsheet code
func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int) {
if buttonIndex == 1 { // Facebook
if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
var controller = SLComposeViewController(forServiceType:SLServiceTypeFacebook)
controller.setInitialText(shareText)
controller.addURL(NSURL(string: appUrl) )
self.presentViewController(controller, animated: true, completion: nil)
controller.completionHandler = { (result:SLComposeViewControllerResult) -> Void in
switch result {
case SLComposeViewControllerResult.Cancelled:
println("fb cancel")
case SLComposeViewControllerResult.Done:
println("done")
}
}
} else {
var alert = UIAlertView(title: "No Facebook Account", message: "Oops, you've not added facebook account in your iphone settings", delegate: self, cancelButtonTitle: "Okay")
alert.show()
}
} else if buttonIndex == 2 { // Twitter
if SLComposeViewController.isAvailableForServiceType(SLServiceTypeTwitter) {
var controller = SLComposeViewController(forServiceType:SLServiceTypeTwitter)
controller.setInitialText(shareText)
controller.addURL(NSURL(string: appUrl) )
self.presentViewController(controller, animated: true, completion: nil)
controller.completionHandler = { (result:SLComposeViewControllerResult) -> Void in
switch result {
case SLComposeViewControllerResult.Cancelled:
println("fb cancel")
case SLComposeViewControllerResult.Done:
println("done")
}
}
} else {
var alert = UIAlertView(title: "No Twitter Account", message: "Oops! Looks like you've not added Twitter account in your settings", delegate: self, cancelButtonTitle: "Okay")
alert.show()
}
}
}
same code works fine on my other apps. Not sure why this is happeing when I click or either facebook or twitter.
