The image of completion is like this!

App side	Instagram story

Image and Label are displayed in View, and the View is converted to image and passed to the Instagram story.

Get date and time

This time, the date is displayed so that it is easy to confirm that the value has changed when it is displayed. Adding variables such as user name to Label will make the design easier to Instagram.

ViewController.swift

@IBOutlet weak var dateLable: UILabel!   //Connect with Storyboard Label
//------------------------------------------------------
//super.viewDidLoad()Described in
let format = DateFormatter()
format.timeStyle = .medium
format.dateStyle = .long
format.locale = Locale(identifier: "ja_JP")
let date = Date()
 dateLable.text = format.string(from: date)

Convert View to UIImage

Let's connect the View created in Storyboard to the ViewController using @IBOutle! After connecting, extend UIView and add the following code to call the image = part at the timing you want to convert.

ViewController.swift

@IBOutlet weak var screensShotView: UIView!   //Connect with Storyboard View
//------------------------------------------------------
//Let's add the following code as an extension of UIVIew.
//view.asImage()You can always convert a View to an Image with.
extension UIView {
    //Code to convert UIView to UIImage
    func asImage() -> UIImage {
        let renderer = UIGraphicsImageRenderer(bounds: bounds)
        return renderer.image { rendererContext in
            layer.render(in: rendererContext.cgContext)
        }
    }
}

//view.asImage()You can convert it to UIImage with. It is better to call it when the button is pressed.
let image = screensShotView.asImage()

Share images to Instagram stories

For a detailed list of Instagram schemes, please see Official Documents.

ViewController.swift

private func setupOpenInstagram() {
        let image = screensShotView.asImage()
        let items: [[String: Any]] = [[
            "com.instagram.sharedSticker.stickerImage": image,
            "com.instagram.sharedSticker.backgroundTopColor": "#000000",
            "com.instagram.sharedSticker.backgroundBottomColor": "#FFFFFF"
        ]]
        UIPasteboard.general.setItems(items, options: [:])
        guard let shareInstagramStoryURL = "instagram-stories://share".convertURL else { return }
        UIApplication.shared.open(shareInstagramStoryURL, options: [:], completionHandler: nil)
    }
