我正在使用UIActivityViewController分享,但在我设置其主题时,特别是它没有设置.请帮忙.
let eventURL = eventShare[sender.tag]
let eventTitleText = eventTitle[sender.tag]
let contentDescription = eventDescription[sender.tag]
let contentURL:NSURL = NSURL(string:eventURL)!
let activityViewController : UIActivityViewController = UIActivityViewController(activityItems: [contentDescription, contentURL],applicationActivities: nil)
activityViewController.setValue("Our Buzz - \(eventTitleText)", forKey: "Subject")
activityViewController.popoverPresentationController?.sourceView = self.view
self.presentViewController(activityViewController, animated: true, completion: nil)
