Question

我希望上下文菜单显示我的应用程序的服务。为此，我编写了以下代码。

根据这个例子：Services Implementation Guide，我在AppDelegate类中为我的服务创建了一个处理程序。

- (void)ServiceHandler:(NSPasteboard *)pboard userData:(NSString *)data error:(NSString **)error
{
    NSLog(@"I clicked");
}

- (void)ServiceHandler2:(NSPasteboard *)pboard userData:(NSString *)data error:(NSString **)error
{
    NSLog(@"I clicked");
}

- (void)ServiceHandler3:(NSPasteboard *)pboard userData:(NSString *)data error:(NSString **)error
{
    NSLog(@"I clicked");
}

然后我在appDidFinishLaunching：方法中将AppDelegate设置为服务提供者，并按如下方式安装服务：

 - (void)applicationDidFinishLaunching:(NSNotification *)aNotification {   
    [NSApp setServicesProvider:self];
    NSUpdateDynamicServices();
}

然后我在info.plist中创建了我的所有服务，如下所示：

<key>NSServices</key>
    <array>
        <dict>
            <key>NSKeyEquivalent</key>
            <dict>

                </array>
            </dict>
        </dict>
    </array>

我通过以下方式注册了我的新文件：

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f /path/to/MyApp

当然我也运行了这个命令：

/System/Library/CoreServices/pbs -update
/System/Library/CoreServices/pbs -flush
/System/Library/CoreServices/pbs -dump_cache

我尝试通过以下方式调试NSServices：

/Applications/TextEdit.app/Contents/MacOS/TextEdit -NSDebugServices com.MyApp

这个命令的结果没问题。

Item 1 (com.MyApp) is enabled in the services menu and enabled in the context menu, by the standard Services policy.
Item 2 (com.MyApp) is enabled in the services menu and enabled in the context menu, by the standard Services policy.
Item 3 (com.MyApp) is enabled in the services menu and enabled in the context menu, by the standard Services policy.

所有内容都已启用，我可以在所选复选框的首选项中看到它们，但在上下文菜单中仍然无法显示此项目。我真的不知道问题出在哪里。有任何想法吗？

编辑：我改变了 NSFilenamesPboardType 上的每个 public.item ，现在正在运行，但只有两个。我仍然无法在上下文菜单服务中查看我自己的扩展程序。有谁知道为什么 public.item 错了？

EDIT2：解决了。我的文件扩展名标识有问题。我改变它现在它的工作原理。

NSService - 添加到上下文菜单中的项目不会显示在mac os x上
