ios - 与自定义类而不是 SLComposeServiceViewController 共享扩展
<p><p>我目前正在使用共享扩展功能。</p>
<p>当我在这里搜索很多时,似乎总是使用 SLComposeServiceViewController 将带有一些文本内容的图像共享给特定的应用程序。</p>
<p>但我希望自定义 UIViewController 类加载从照片应用程序中选择的图像,当打开 <code>共享表上的邮件扩展名</code></p>时,它与邮件编辑器一样
<p>所以我得到了这个示例,并按照下面的 git hub 链接(第二个)中的说明进行操作:</p>

<li> <a href="https://github.com/martinnormark/ShareByMail" rel="noreferrer noopener nofollow">https://github.com/martinnormark/ShareByMail</a> </li>
</ul>
<p>是的,似乎 <code>4 年前</code> 所以迁移并转换为 <code>Swift 4.1</code> 版本。在我修改了这些更改并调试它之后。它不像在 GitHub gif 上那样工作。是的,最初时,当我在共享表上触摸扩展应用程序时,我可以呈现和关闭 Controller 。但是在我解散并再次尝试呈现它之后,这一次它在 GitHub gif 上没有反应。</p>
<p>Martin 只显示和隐藏 <code>UINavigationController Y 位置值的self.view</code>。一旦我按下 <code>Cancel 或 save</code> 栏按钮,然后我尝试通过共享表上的扩展触摸打开它,它不起作用并且那里没有反应。</p>
<p>这里是 <code>NSExtensionPrincipalClass - EntryViewController</code></p> 的源代码
<pre><code>import UIKit
@objc(EntryViewController)
class EntryViewController : UINavigationController {
init() {
super.init(rootViewController: ShareViewController())
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
}
override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.view.transform = CGAffineTransform(translationX: 0, y: self.view.frame.size.height)
UIView.animate(withDuration: 0.25, animations: { () -> Void in
self.view.transform = CGAffineTransform.identity
}, completion: nil)
}
}
import UIKit
import Social
class ShareViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = .white
self.navigationItem.title = "Share this"
self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .cancel, target: self, action: #selector(self.cancelButtonTapped(_:)))
self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .save, target: self, action: #selector(self.saveButtonTapped(_:)))
}
@objc func saveButtonTapped(_ sender: UIBarButtonItem) {
self.hideExtensionWithCompletionHandler(completion: { (Bool) -> Void in
self.extensionContext!.completeRequest(returningItems: nil, completionHandler: nil)
})
}
@objc func cancelButtonTapped(_ sender: UIBarButtonItem) {
self.hideExtensionWithCompletionHandler(completion: { (Bool) -> Void in
self.extensionContext!.cancelRequest(withError: NSError())
})
}
func hideExtensionWithCompletionHandler(completion:(Bool) -> Void) {
UIView.animate(withDuration: 0.20, animations: { () -> Void in
self.navigationController!.view.transform = CGAffineTransform(translationX: 0, y: self.navigationController!.view.frame.size.height)
}, completion: nil)
}
}

<p>如何查找和修复上述尝试中的问题或如何进行自定义 UIViewController 布局而不是使用 <code>SLComposeServiceViewController</code>?</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>在您的 ViewController 上(按钮操作方法)</p>
<h3> objective-c </h3>
<p>当你完成你的过程时调用它</p>
<pre><code> completionHandler:nil];
</code></pre>
<p>当您/用户取消您的流程时调用它</p>
<pre><code>NSError *error = ;
;
</code></pre>
<h3> swift </h3>
<p>当你完成你的过程时调用它</p>
<pre><code>self.extensionContext?.completeRequestReturningItems([], completionHandler:nil)
</code></pre>
<p>当您/用户取消您的流程时调用它</p>
<pre><code>let cancelError = NSError(domain: NSCocoaErrorDomain, code: NSUserCancelledError, userInfo: nil)
self.extensionContext!.cancelRequestWithError(cancelError)
</code></pre>
<p>如果您有任何 API 错误</p>
<pre><code>self.extensionContext!.cancelRequestWithError(error as NSError)
</code></pre>
<h3>更新</h3>
<p>在您的代码中,您没有在此方法中调用完成处理程序 <code>hideExtensionWithCompletionHandler</code></p>
<pre><code>func hideExtensionWithCompletionHandler(completion:@escaping (Bool) -> Void) {
UIView.animate(withDuration: 0.20, animations: { () -> Void in
self.navigationController!.view.transform = CGAffineTransform(translationX: 0, y: self.navigationController!.view.frame.size.height)
}, completion: { (_) -> Void in
completion(true)
})
}
</code></pre></p>
