我正在尝试使用standard共享图像UIActivityViewController，可以使用以下代码在 ，

和 共享：

let firstActivityItem = "foo text"
let secondActivityItem : UIImage = image!
let activityViewController : UIActivityViewController = UIActivityViewController(
    activityItems: [firstActivityItem, secondActivityItem], applicationActivities: nil)
activityViewController.excludedActivityTypes = [
    UIActivityTypePostToWeibo,
    UIActivityTypePrint,
    UIActivityTypeAssignToContact,
    UIActivityTypeAddToReadingList,
    UIActivityTypePostToVimeo,
    UIActivityTypePostToTencentWeibo
]
self.presentViewController(activityViewController, animated: true, completion: nil)

我还需要一件事， ：

If UIApplication.sharedApplication().canOpenURL(instagramURL!) {
            // Success
            var img = image!
            var savePath: String = NSHomeDirectory().stringByAppendingPathComponent("Documents/Test.igo")
            UIImageJPEGRepresentation(img, 1).writeToFile(savePath, atomically: true)
            var imgURL = NSURL(string: NSString(format: "file://%@", savePath) as! String)
            docController = UIDocumentInteractionController(URL: imgURL!) // 1
            docController.UTI = "com.instagram.exclusivegram" // 2
            docController.delegate = self
            docController.annotation = ["InstagramCaption":"testsss"] // 3
            docController.presentOpenInMenuFromRect(self.view.frame, inView: self.view, animated: true) // 4
        } else {
            // Error
        }

这两个代码分别工作正常，如何将 添加到UIActivityViewController？有可能吗？

回答：

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UIDocumentInteractionControllerDelegateUIViewController类。
