Ios 网间网操作系统。在不使用菜单显示的情况下将图像共享到Instagram

有人可以帮助并解释如何在不显示菜单的情况下共享Instagram吗？例如，应用程序Prisma在不使用菜单显示的情况下执行此操作。

必须执行以下操作：

将照片保存到照片库

获取已保存照片的资源url

使用此URL通过URL方案打开Instagram

instagram://library?AssetPath=ASSET_PATH

其中，ASSET_PATH是在第二步中获取的资产url

Swift 3上的代码示例：

let library = ALAssetsLibrary()
library.writeImage(toSavedPhotosAlbum: image.cgImage, metadata: nil) { (url, error) in
    if let url = url {
        DispatchQueue.main.async {
            let path = url.absoluteString.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)
            let instagram = URL(string: "instagram://library?AssetPath=\(path)")
            UIApplication.shared.open(instagram!)
        }
    }
}

您必须这样做：

将照片保存到照片库

获取已保存照片的资源url

使用此URL通过URL方案打开Instagram

instagram://library?AssetPath=ASSET_PATH

其中，ASSET_PATH是在第二步中获取的资产url

Swift 3上的代码示例：

let library = ALAssetsLibrary()
library.writeImage(toSavedPhotosAlbum: image.cgImage, metadata: nil) { (url, error) in
    if let url = url {
        DispatchQueue.main.async {
            let path = url.absoluteString.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)
            let instagram = URL(string: "instagram://library?AssetPath=\(path)")
            UIApplication.shared.open(instagram!)
        }
    }
}

我知道这是一个老问题，但我只是想为那些可能正在寻找答案的人提供一个更新的答案

Vitaly Berg有正确的方法处理不推荐的代码。以下是对我有效的最新代码（Swift 5）：

@IBAction func instagramButtonClicked(_ sender: Any) {

            //check and see if we can save photos
            let status = PHPhotoLibrary.authorizationStatus()
            if (status == PHAuthorizationStatus.authorized) {
                // Access has been granted.
                self.shareToInstagram(theImage!)
            }else if (status == PHAuthorizationStatus.denied) {

        placeHolder = creationRequest.placeholderForCreatedAsset!
    }, completionHandler: { success, error in
        guard success, let placeholder = placeHolder else {
            completion(nil)
            return
        }
        let assets = PHAsset.fetchAssets(withLocalIdentifiers: [placeholder.localIdentifier], options: nil)
        guard let asset = assets.firstObject else {
            completion(nil)
            return
        }
        asset.requestContentEditingInput(with: nil, completionHandler: { (editingInput, _) in
            completion(editingInput?.fullSizeImageURL)
        })
    })
}

菜单是指UIActivityController吗？我是指UIDocumentInteractionController。我无法在此处访问此instagram文档，其中包含相关信息。你可以搜索“iPhone Instagram Hooks”以获取更多信息。谢谢，但我熟悉此说明，这不是我要查找的。菜单中的“UIActivityController”是指UIDocumentInteractionController吗？我指的是UIDocumentInteractionController。我无法在此处访问此Instagram文档，其中包含相关信息。您可以搜索“iPhone Instagram Hooks”以获取更多信息。谢谢，但我熟悉此说明，这不是我想要的。
