使用iOS中的照片框架将视频保存到自定义相册

我想使用

照片框架将使用自定义照相机拍摄的视频保存到
照片库
中的特定相册，例如
新相册
。
我已经找到了一些答案，但是他们提到了
ALAssetsLibrary
的使用，现在已经不推荐了

请让我知道，如果你需要任何更多的细节，也纠正我，如果我错过了什么。
谢谢
我找到了一个解决方案：

代码块1:

PhotoLibrary.shared().performChanges({
    let createAssetRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(/*Your url here*/)
    placeholder = createAssetRequest.placeholderForCreatedAsset
    identifier = placeholder.localIdentifier
}, completionHandler: {
    success, error in 
    /* 
       Fetch Asset with the identifier here
       after that, add the PHAsset into an album
    */
    newAsset = PHAsset.fetchAssets(withLocalIdentifiers: [identifier], options: nil).firstObject
}

// Consider we have a known localIdentifier for a specific PHAssetCollection defined as -> let collectionIdentifier: String
guard let collection: PHAssetCollection = PHAssetCollection.fetchAssetCollections(withLocalIdentifiers: [collectionIdentifier], options: nil).fistObject else {
   // handle Error
   return
}
PhotoLibrary.shared().performChanges({

    guard let addAssetRequest = PHAssetCollectionChangeRequest(for: collection) else { return }

    addAssetRequest.addAssets([newAsset] as NSArray)
}, completionHandler: {
    success, error in
    //handle error or stuff you want to do after that here
})

您可以使用以下代码段添加
PHAsset
：

代码块2:

PhotoLibrary.shared().performChanges({
    let createAssetRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(/*Your url here*/)
    placeholder = createAssetRequest.placeholderForCreatedAsset
    identifier = placeholder.localIdentifier
}, completionHandler: {
    success, error in 
    /* 
       Fetch Asset with the identifier here
       after that, add the PHAsset into an album
    */
    newAsset = PHAsset.fetchAssets(withLocalIdentifiers: [identifier], options: nil).firstObject
}

// Consider we have a known localIdentifier for a specific PHAssetCollection defined as -> let collectionIdentifier: String
guard let collection: PHAssetCollection = PHAssetCollection.fetchAssetCollections(withLocalIdentifiers: [collectionIdentifier], options: nil).fistObject else {
   // handle Error
   return
}
PhotoLibrary.shared().performChanges({

    guard let addAssetRequest = PHAssetCollectionChangeRequest(for: collection) else { return }

    addAssetRequest.addAssets([newAsset] as NSArray)
}, completionHandler: {
    success, error in
    //handle error or stuff you want to do after that here
})

编辑创建
阶段集合的示例

在本例中，我在
performChanges（:，completionHandler:）
闭包中创建了create
PHAssetCollection
，然后将其放入该函数的
@escaping
闭包中

PHPhotoLibrary.shared().performChanges({

        let createRequest = PHAssetCollectionChangeRequest.creationRequestForAssetCollection(withTitle: name)
        placeHolderIdentifier = createRequest.placeholderForCreatedAssetCollection.localIdentifier

    }, completionHandler: {
        success, error in
        if success {
            var createdCollection: PHAssetCollection? = nil
            if placeHolderIdentifier != nil {
                createdCollection = PHAssetCollection.fetchAssetCollections(withLocalIdentifiers: [placeHolderIdentifier!], options: nil).firstObject
            }
            completion(success, createdCollection as? T)
        } else {
            LogError("\(error)")
            completion(success, nil)
        }
    })

谢谢你。我会检查并让你知道的。@Ankit Kumar Gupta那么它起作用了吗？还是你还在为某事苦苦挣扎？抱歉@Marcel本周还有其他一些优先事项。当然会测试它，并在下一个测试中让您知道。@user25当您看到第一个代码块时，您会看到
PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL（/*此处的url*/）
就像在示例中一样，您需要获取占位符标识符。在完成处理程序中，使用
PHAsset.fetchAssets（withLocalIdentifier:[identifier]，options:nil）获取创建的资产。firstObject
其中
identifier
是占位符标识符，并添加资产，就像在第二个代码块中提到的那样。我现在将用粗体文字标记这些块：）@user25祝你好运，我将从你的搜索开始，它看起来很有希望，我以前从未做过类似的事情。
