Question

我创建了通过电子邮件发送或打印文件的代码。

但我想添加更多选项，例如通过Gmail发送，将文件保存到iBooks，保存到Dropbox等。

我添加了两个需求：电子邮件和打印。我想添加一个Gmail和几个选项。

以下是代码：

func actionMenuViewControllerShareDocument(_ actionMenuViewController: ActionMenuViewController) {
    let mailComposeViewController = MFMailComposeViewController()
    if let lastPathComponent = pdfDocument?.documentURL?.lastPathComponent,
        let attachmentData = pdfDocument?.dataRepresentation() {

        mailComposeViewController.addAttachmentData(attachmentData, mimeType: "application/pdf", fileName: lastPathComponent)
    }
}

func actionMenuViewControllerPrintDocument(_ actionMenuViewController: ActionMenuViewController) {
    let printInteractionController = UIPrintInteractionController.shared
    printInteractionController.printingItem = pdfDocument?.dataRepresentation()
    printInteractionController.present(animated: true, completionHandler: nil)
}

代码2

import UIKit

class ActionMenuViewController: UITableViewController {
    weak var delegate: ActionMenuViewControllerDelegate?

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.isScrollEnabled = false
        tableView.separatorInset = .zero
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if indexPath.row == 0 {
            delegate?.actionMenuViewControllerShareDocument(self)
        } else if indexPath.row == 1 {
            delegate?.actionMenuViewControllerPrintDocument(self)

        tableView.deselectRow(at: indexPath, animated: true)
    }
}

protocol ActionMenuViewControllerDelegate: class {
    func actionMenuViewControllerShareDocument(_ actionMenuViewController: ActionMenuViewController)
    func actionMenuViewControllerPrintDocument(_ actionMenuViewController: ActionMenuViewController)

}

尝试以下操作，您将获得多种选项，例如通过Gmail发送，将文件保存到iBooks，保存到Dropbox等，这些都是iPhone的支持。

假设您在文档目录中有.pdf文件。

    var paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
    let documentsDirectory: String = paths[0]
    let fullPath: String = URL(fileURLWithPath: documentsDirectory).appendingPathComponent("\("FileName").pdf").absoluteString
    let url = URL(fileURLWithPath: fullPath)
    let activityItems = [url]
    let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

    self.present(activityViewController, animated: true, completion: nil)

如何为发送文件添加更多选项
