共享扩展 ios swift

Question

我创建了一个包含一些按钮的共享扩展，并用 UIViewcontroller 继承了该扩展。当我创建那些 UIButtons 的 @IBAction 时，它永远不会在单击按钮时被调用。

import UIKit
import Social

class ShareViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
    }
    
    
//    override func isContentValid() -> Bool {
//        // Do validation of contentText and/or NSExtensionContext attachments here
//        return true
//    }
//
//    override func didSelectPost() {
//        // This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
//    
//        // Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
//        self.extensionContext!.completeRequest(returningItems: [], completionHandler: nil)
//    }
//
//    override func configurationItems() -> [Any]! {
//        // To add configuration options via table cells at the bottom of the sheet, return an array of SLComposeSheetConfigurationItem here.
//        return []
//    }

    @IBAction func btnBackClicked(_ sender: Any) {
        self.dismiss(animated: true, completion: nil)
    }
    @IBAction func btnCancleClicked(_ sender: Any) {
        self.dismiss(animated: true, completion: nil)
    }
    @IBAction func btnSaveClicked(_ sender: Any) {
        
    }
}

我认为正在调用您的按钮操作，只是调用 self.dismiss(animated: true, completion: nil) 不会真正关闭您的共享扩展。

关于这个，你应该使用：

self.extensionContext!.completeRequest(returningItems: nil, completionHandler: nil)

或

self.extensionContext!.cancelRequest(withError:NSError(domain: Bundle.main.bundleIdentifier!, code: 0))
