社交框架iOS 8 Swift

所以我一直在写一个应用程序，需要使用社会框架通过Twitter和Facebook分享文本。

我得到它的工作，但它并没有解雇（？），然后我想起了完成处理程序，但无论我做这个处理程序不断给我错误。

var okFacebook :Bool = SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) var okTwitter :Bool = SLComposeViewController.isAvailableForServiceType(SLServiceTypeTwitter) var okLinkedIn : Bool = SLComposeViewController.isAvailableForServiceType(SLServiceTypeLinkedIn) var socialVC :SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeTwitter) socialVC.completionHandler = SLComposeViewControllerCompletionHandler(SLComposeViewControllerResult) -> Void self.presentViewController(socialVC, animated: true, completion: nil) 

Answer 1

尝试下面的代码，尚未testing

  socialVC.completionHandler = { (result:SLComposeViewControllerResult) in // Your code } 

Answer 2

  override func viewDidLoad() { super.viewDidLoad() if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook){ var facebookSheet:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook) facebookSheet.setInitialText("Hiya, I have just discovered this great app called Dwingle, which I think you're going to love.") let url = NSURL(string: "") facebookSheet.addURL(url) self.presentViewController(facebookSheet, animated: true, completion: nil) facebookSheet.completionHandler = { result -> Void in self.dismissViewControllerAnimated(true, completion: { () -> Void in self.navigationController?.popToRootViewControllerAnimated(true) }) } } else { var alert = UIAlertController(title: "Accounts", message: "Please login to a Facebook account to share.", preferredStyle: UIAlertControllerStyle.Alert) alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)) self.presentViewController(alert, animated: true, completion: nil) } }
