将Instagram添加到UIActivityViewController

将Instagram添加到UIActivityViewController

我认为将其他社交共享添加到您为Instagram编写的代码中会更加容易。“
.igo”扩展名是Instagram专有的，因此其他应用程序将不支持它。只需将此扩展名从“ .igo”更改为“ .ig”，其他应用程序就会读取它：

var savePath: String = NSHomeDirectory().stringByAppendingPathComponent("documents/Test.ig")

但是Instagram还具有专有的UTI，可避免其他应用程序出现在同一文档交互视图中。因此，您还需要将其从“独占图”更改为“照片”：

docController.UTI = "com.instagram.photo"

我有一个具有类似功能的应用，这是我的原始代码：

@IBAction func shareonIntagram(sender: UIButton) {        let finalImage: UIImage = UIImage.imageWithView(photoView)        let instagramURL = NSURL(string: "instagram://app")        if (UIApplication.sharedApplication().canOpenURL(instagramURL!)) { let imageData = UIImageJPEGRepresentation(finalImage, 1) let captionString = "caption" let writePath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagram.ig") if imageData?.writeToFile(writePath, atomically: true) == false {     return } else {     let fileURL = NSURL(fileURLWithPath: writePath)     self.documentController = UIdocumentInteractionController(URL: fileURL)     self.documentController.delegate = self     self.documentController.UTI = "com.instagram.photo"     self.documentController.annotation = NSDictionary(object: captionString, forKey: "InstagramCaption")     self.documentController.presentOpenInMenuFromRect(self.view.frame, inView: self.view, animated: true) }        } else { print(" Instagram is not installed ")        }    }

为了使此代码正常工作，请不要忘记添加

UIdocumentInteractionControllerDelegate

UIViewController类。
