如何在Swift 3 iOS 10中创建自定义相册

import UIKit
import Photos

func createCustomAlbum() {
    let albumTitle = "My Custom Album"
    
    // 请求相册访问权限
    PHPhotoLibrary.requestAuthorization { status in
        if status == .authorized {
            // 创建自定义相册
            PHPhotoLibrary.shared().performChanges({
                PHAssetCollectionChangeRequest.creationRequestForAssetCollection(withTitle: albumTitle)
            }) { success, error in
                if success {
                    // 获取刚创建的自定义相册
                    let fetchOptions = PHFetchOptions()
                    fetchOptions.predicate = NSPredicate(format: "title = %@", albumTitle)
                    let collection = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: fetchOptions)
                    
                    if let album = collection.firstObject {
                        // 添加照片到自定义相册
                        PHPhotoLibrary.shared().performChanges({
                            let image = UIImage(named: "example.jpg") // 替换为你要添加的照片
                            let creationRequest = PHAssetChangeRequest.creationRequestForAsset(from: image!)
                            let addAssetRequest = PHAssetCollectionChangeRequest(for: album)
                            addAssetRequest?.addAssets([creationRequest.placeholderForCreatedAsset!] as NSArray)
                        }) { success, error in
                            if success {
                                print("照片已添加到自定义相册")
                            } else {
                                print("添加照片到自定义相册失败: \(error?.localizedDescription ?? "")")
                            }
                        }
                    }
                } else {
                    print("创建自定义相册失败: \(error?.localizedDescription ?? "")")
                }
            }
        } else {
            print("相册访问权限被拒绝")
        }
    }
}

// 调用函数创建自定义相册
createCustomAlbum()
