Here is my code so far, but i get an error that UIBarButtonItem Is not convetable to UIVIew Why? The action is connected to a navigation bar button item?
#IBAction func ActionButton(sender: UIBarButtonItem) {
let firstActivityItem = "Text you want"
let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!
// If you want to put an image
let image : UIImage = UIImage(named: "TALogo")!
let activityViewController : UIActivityViewController = UIActivityViewController(
activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
// This lines is for the popover you need to show in iPad
activityViewController.popoverPresentationController?.sourceView = (sender as! UIBarButtonItem)
// This line remove the arrow of the popover to show in iPad
activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.allZeros
activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
// Anything you want to exclude
activityViewController.excludedActivityTypes = [
UIActivityTypePostToWeibo,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo
]
self.presentViewController(activityViewController, animated: true, completion: nil)
}

The way is using UIActivityViewController for example in the following way :
#IBAction func shareSheet(sender: AnyObject) {
let firstActivityItem = "Text you want"
let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!
// If you want to put an image
let image : UIImage = UIImage(named: "image.jpg")!
let activityViewController : UIActivityViewController = UIActivityViewController(
activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
// This lines is for the popover you need to show in iPad
activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)
// This line remove the arrow of the popover to show in iPad
activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.allZeros
activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
// Anything you want to exclude
activityViewController.excludedActivityTypes = [
UIActivityTypePostToWeibo,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo
]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
The above code works for both iPhone and iPad because in you set the new popoverPresentationController in iOS 8 it works for iPad too.
In the case of use an UIBarButtonItem you need to replace this line:
activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)
With this one:
activityViewController.popoverPresentationController?.barButtonItem = (sender as! UIBarButtonItem)
I hope this help you.
