ios - 如何打印 SFSafariViewController 完整网页？

Question

我在 SFSafariViewController 中打开一个 pdf 文件。现在我想从 SFSafariViewController 打印这个 PDF。

但是 safari view controller 的分享按钮没有打印选项。

请告诉我如何将打印功能添加到 SFSafariViewController。

您可以自定义事件。

    extension ViewController: SFSafariViewControllerDelegate {
        func safariViewController(_ controller: SFSafariViewController, activityItemsFor URL: URL, title: String?) -> [UIActivity] {
            let acitivity = CustomActivity()
            return [acitivity]
        }

        func printURL(url: URL) {
        }
    }

自定义事件.swift

import Foundation
import UIKit

class CustomActivity: UIActivity {
    override class var activityCategory: UIActivityCategory {
        return .action
    }

    override var activityType: UIActivityType? {
        return UIActivityType.print
    }

    override var activityTitle: String? {
        return "Print"
    }

    override var activityImage: UIImage? {
        return nil
    }

    override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
        return true
    }

    override func perform() {
        // do something here
    }

}
