[英]Post To Instagram screen on iOS Swift
我正在嘗試使從我的應用程序共享到 Instagram 變得容易。 我想要的是進入下面屏幕截圖所示的屏幕。 我試過 instagram-stories://share deeplink 並且我已經閱讀了所有這些文檔: https : //developers.facebook.com/docs/instagram/sharing-to-stories/
但是,無論我做什么,當 url 方案操作觸發時,它都會直接將圖像共享到故事中。 我在這里缺少什么?
這是我的代碼摘錄:
if let image = image {
guard let urlScheme = URL(string: "instagram-stories://share"),
let imageData = image.pngData() else {
return
}
if UIApplication.shared.canOpenURL(urlScheme) {
let pasterboardItems = [["com.instagram.sharedSticker.backgroundImage": imageData]]
let pasterboardOptions = [UIPasteboard.OptionsKey.expirationDate: Date().addingTimeInterval(60*5)]
UIPasteboard.general.setItems(pasterboardItems, options: pasterboardOptions)
UIApplication.shared.open(urlScheme, options: [:], completionHandler: nil)
}
}
您需要做的是使用以下網址打開 Instagram 應用程序:
instagram://library?LocalIdentifier=
並作為參數傳遞PHAsset.localIdentifier
。
出於某種原因,這個鈎子沒有在文檔中的任何地方列出🤷♂️
但是為了接收您的圖像/視頻的本地標識符,您必須首先將圖像/視頻保存到用戶的照片庫中。 所以最終的代碼看起來像這樣
let videoFileUrl: URL = URL(fileURLWithPath: "path/to/my/video")!
var localId: String?
PHPhotoLibrary.shared().performChanges({
let request = PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: videoFileUrl)
localId = request?.placeholderForCreatedAsset?.localIdentifier
}, completionHandler: { success, error in
// completion handler is called on an arbitrary thread
// but since you (most likely) will perform some UI stuff
// you better move everything to the main thread.
DispatchQueue.main.async {
guard error == nil else {
// handle error
return
}
guard let localId = localId else {
// highly unlikely that it'll be nil,
// but you should handle this error just in case
return
}
let url = URL(string: "instagram://library?LocalIdentifier=\(localId)")!
guard UIApplication.shared.canOpenURL(url) else {
// handle this error
return
}
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
})
image
是“png”LSApplicationQueriesSchemes
