Question

我正在尝试在TableViewCell中实现将按钮用于文本和图像的共享按钮。这段代码很完美，但是我希望TableViewCell中的数据能够动态使用。

@IBAction func tapShareButton(_ sender: UIButton) {
     //Shoename should be the releasename
    let firstActivityItem = "Find out everywhere the *shoename* is available to purchase"
    let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!
    // Image should be the releaseimage
    let image : UIImage = UIImage(named: "image.jpg")!

    let activityViewController : UIActivityViewController = UIActivityViewController(
        activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)

    activityViewController.popoverPresentationController?.sourceView = (sender )
            activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)

    // Anything you want to exclude
    activityViewController.excludedActivityTypes = [
        UIActivity.ActivityType.postToWeibo,
        UIActivity.ActivityType.print,
        UIActivity.ActivityType.assignToContact,
        UIActivity.ActivityType.saveToCameraRoll,
        UIActivity.ActivityType.addToReadingList,
        UIActivity.ActivityType.postToFlickr,
        UIActivity.ActivityType.postToVimeo,
        UIActivity.ActivityType.postToTencentWeibo
    ]

    self.presentViewController(activityViewController, animated: true, completion: nil)
}

public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    let cell = tableView.dequeueReusableCell(withIdentifier: "ReleaseCell", for: indexPath) as! ReleaseTableViewCell
    var release: ReleaseModel
    release = releasesData[indexPath.row]

    cell.releaseType.text = release.releasetype
    cell.releaseName.text = release.releasename
    cell.releaseDate.text = release.releasedate
    cell.releaseImage.sd_setImage(with: URL(string: release.releaseimage!), placeholderImage: UIImage(named: "placeholder1"))

    cell.delegate = self
    return cell
}

使用按钮位置获取单元格的indexPath，然后从模型对象中提取特定数据。

编辑：

您可以直接与if (process.env.NODE_ENV === 'development') {//path dev -> min to product app.use('/js', express.static('client/js/dev')) app.use('/css', express.static('client/css/dev')) }中的文本一起共享图像，因为在URL中共享图像之前，您需要先下载图像，否则可以通过将其保存在数组中来直接共享图像。

UIActivityViewController
