Question

我甚至不知道这是否可行，但我想知道是否有任何方式你可以将UIView及其所有内容插入推文或facebook帖子中，这样当用户从应用程序发出推文时，图像UIView的内容显示在推文中。任何帮助表示赞赏。这是我的尝试，它说//这条线没有做任何事情：

func sendSocialPost(serviceType:String) {

    if SLComposeViewController.isAvailableForServiceType(serviceType) {

        // Users device is good for Twitter
        let socialDialog:SLComposeViewController = SLComposeViewController(forServiceType: serviceType)

        socialDialog.setInitialText("Whats the mood like?")

        // THIS LINE DOES NOT DO ANYTHING
        socialDialog.inputAccessoryView?.insertSubview(self.scrollViewView, aboveSubview: self.contentView)

        socialDialog.completionHandler = { (result:SLComposeViewControllerResult) in

            // Check if the user sent the tweet of cancelled it
            if result == SLComposeViewControllerResult.Done {
                // User has sent social post
                NSLog("post sent")
            }
            else if result == SLComposeViewControllerResult.Cancelled {
                NSLog("post cancelled")
            }
        }

        // Present the social dialog box
        self.presentViewController(socialDialog, animated: true, completion: nil)

    }
    else {

        // Social Account credentials haven't been added to the settings
        if serviceType == SLServiceTypeTwitter {
            NSLog("A Twitter account needs to be set up in the Settings app.")
        }
        else if serviceType == SLServiceTypeFacebook {
            NSLog("A Facebook account needs to be set up in the Settings app.")
        }

    }

}

您可以捕获UIImage的视图并发推文...... 如果这就是你的意思..

    func captureViewArea() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(self.viewToCapture.bounds.size, self.viewToCapture.opaque, 0.0)
        self.viewToCapture.layer.renderInContext(UIGraphicsGetCurrentContext())
        let viewImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return viewImage
    }
