使用背景图片和贴纸向 Instagram 分享故事 - IOS Swift

Question

I'm trying to share a story with a background image aa sticker image via URL Scheme on my ios app, i am using the attached code and it dose not work. When i'm trying to share just a background image or just a sticker it does work. But when im trying share both a background image and a sticker in top of it, it dose not work.

Any Ideas?

func shareToInstagram(deepLinkString : String){
        let url = URL(string: "instagram-stories://share")!
        if UIApplication.shared.canOpenURL(url){

            let backgroundData = UIImageJPEGRepresentation(UIImage(named: "shop_placeholder")!, 1.0)!
            let creditCardImage = UIImage(named: "share_instagram")!
            let stickerData = UIImagePNGRepresentation(creditCardImage)!
            let pasteBoardItems = [
                                    ["com.instagram.sharedSticker.backgroundImage" : backgroundData],
                                    ["com.instagram.sharedSticker.stickerImage" : stickerData],
                                  ]

            if #available(iOS 10.0, *) {

                UIPasteboard.general.setItems(pasteBoardItems, options: [.expirationDate: Date().addingTimeInterval(60 * 5)])
            } else {
                UIPasteboard.general.items = pasteBoardItems
            }
            UIApplication.shared.openURL(url)
        }

Answer 1

I copy pasted OP's code for use in my own app (only substituting different UIImages) and found only 1 issue, pasteboard items should be contained in a single array otherwise instagram will render only the first item (in this case the background layer). To fix this, replace the declaration of pasteboard items with the following code

let pasteBoardItems = [
                ["com.instagram.sharedSticker.backgroundImage" : backgroundData,
                "com.instagram.sharedSticker.stickerImage" : stickerData]
            ]

(basically just remove the close and open bracket separating the two items)

Also as a previous answer stated, make sure "instagram-stories" is included in LSApplicationQueriesSchemes in the info.plist file

I use this exact code in my app and it now works perfect

Answer 2

Everything is correct, my code is similar and it works for iOS 11+. I suggest you the following:

1. check the image data you pass to pasteboard (jpg can't be converted with UIImagePNGRepresentation and vice versa)
2. check the info.plist. You should enable "instagram-stories" scheme in it ( LSApplicationQueriesSchemes key)

Answer 3

1. Like Alec said, you need to put all of Instagram data in one list, not multiple lists. look at the example from the meta documents :

NSArray *pasteboardItems = @[@{@"com.instagram.sharedSticker.stickerImage" : stickerImage,
                               @"com.instagram.sharedSticker.backgroundTopColor" : backgroundTopColor,
                               @"com.instagram.sharedSticker.backgroundBottomColor" : backgroundBottomColor}];

2. For more recent readers, as of swift 4.2 and iOS 12 UIImageJPEGRepresentation is replaced by jpegData. change

let backgroundData = UIImageJPEGRepresentation(yourImage, 1.0)

with

let backgroundData = yourImage.jpegData(compressionQuality: 1.0)
