ios - 如何打印 SFSafariViewController 完整网页？
<p><p>我正在 <code>SFSafariViewController</code> 中打开一个 pdf 文件。现在我想从 <code>SFSafariViewController</code> 打印这个 PDF。</p>
<p>但是 SafariViewController 的分享按钮没有打印选项。</p>
<p>请告诉我如何向 <code>SFSafariViewController</code> 添加打印功能。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您可以自定义事件。</p>
<pre><code> extension ViewController: SFSafariViewControllerDelegate {
func safariViewController(_ controller: SFSafariViewController, activityItemsFor URL: URL, title: String?) -> {
let acitivity = CustomActivity()
return
}
func printURL(url: URL) {
}
}
</code></pre>
<p>CustomActivity.swift</p>
<pre><code>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: ) -> Bool {
return true
}
override func perform() {
// do something here
}
}
</code></pre>
