如何在instagram swift上与自定义内容共享链接

Question

我想在instagram上共享应用程序，图像和文本的链接是否无法在instagram上显示预填充文本？是否可以通过iOS应用在instagram上共享链接。以下是我的快速代码，请建议我。图片分享成功，如何与文字分享？

以下代码：

import UIKit

class ViewController: UIViewController,UIDocumentInteractionControllerDelegate {

private let documentInteractionController = UIDocumentInteractionController()
private let kInstagramURL = "instagram://"
private let kUTI = "com.instagram.photo" //"com.instagram.exclusivegram"
private let kfileNameExtension = "instagram.ig"//"instagram.igo"
private let kAlertViewTitle = "Error"
private let kAlertViewMessage = "Please install the Instagram application"

var imageInstagram = UIImage()
let instagramCaption = String()

func shareToInstaGram() {
    let img = UIImage(named: "Logo")
    imageInstagram = img!
    let instagramURL = NSURL(string: kInstagramURL)
    if UIApplication.shared.canOpenURL(instagramURL! as URL) {
        let jpgPath = (NSTemporaryDirectory() as NSString).appendingPathComponent(kfileNameExtension)
        do {
            try imageInstagram.jpegData(compressionQuality: 0.75)?.write(to: URL(fileURLWithPath: jpgPath), options: .atomic)
        } catch {
            print(error)
        }
        let rect = CGRect.zero
        let fileURL = NSURL.fileURL(withPath: jpgPath)
        documentInteractionController.url = fileURL
        documentInteractionController.delegate = self
        documentInteractionController.uti = kUTI
        documentInteractionController.annotation = ["InstagramCaption": "desTitl"]
        documentInteractionController.presentOpenInMenu(from: rect, in: view, animated: true)
       }
    }
 }

有人可以向我解释如何与图片共享文本。任何帮助将不胜感激。

提前感谢。

使用UIActivityViewController将您的图片和文字发布在任何已安装的社交媒体应用上。
