如果您的操作扩展无法打开，请确保已将其正确配置并与主应用程序和扩展点关联。您还应检查环境和权限设置，以确保操作扩展可以在应用程序中正确运行。以下是一个可能的示例代码，其中包含操作扩展配置和启动代码：

// 在操作扩展的 info.plist 文件中配置扩展点和相关应用程序
NSExtension

    NSExtensionAttributes
    
        NSExtensionActivationRule
        SUBQUERY (
            extensionItems,
            $extensionItem,
            SUBQUERY (
                $extensionItem.attachments,
                $attachment,
                (
                    ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.url"
                    || ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.image"
                )
            ).@count >= 1
        ).@count >= 1
    
    NSExtensionMainStoryboard
    MainInterface
    NSExtensionPointIdentifier

// 在应用程序中启动操作扩展
- (void)performActionWithItem:(SLComposeSheetConfigurationItem *)item
{
    NSExtensionContext *context = [item.userInfo objectForKey:SLComposeSheetConfigurationItemExtensionContext];
    NSArray *attachments = context.inputItems.firstObject.attachments;
    for (NSItemProvider *attachment in attachments) {
        if ([attachment hasItemConformingToTypeIdentifier:@"public.url"]) {
            [attachment loadItemForTypeIdentifier:@"public.url"
                                           options:nil
                                 completionHandler:^(id item, NSError *error) {
                                     if (error == nil && [item isKindOfClass:[NSURL class]]) {
                                         NSURL *url = (NSURL *)item;
                                         // 处理 URL
                                     }
                                 }];
        }
        else if ([attachment hasItemConformingToTypeIdentifier:@"public.image"]) {
            [attachment loadItemForTypeIdentifier
