剪切/复制/粘贴键盘快捷键在NSPopover中不起作用 [英] Cut/copy/paste keyboard shortcuts not working in NSPopover

问题描述

我有一个基于macOS NSPopover的任务栏应用程序，其中显示了一个带有登录字段(用户名和密码)的弹出式窗口.

I have a macOS NSPopover based tray app which shows a popover with login fields (username and password).

问题是用户无法将其电子邮件或密码复制粘贴到文本字段中.由于某些原因，弹出窗口似乎不允许键盘快捷键.

Problem is that user is unable to copy-paste his email or password into text fields. The popover doesn't seem to allow keyboard shortcuts for some reason.

有人有类似的问题吗?

推荐答案

这不是最容易解决的问题，您需要做一些事情才能使它起作用.

This isn't the easiest thing to solve and you need to do a few things to get this to work.

1)将MainMenu添加到MainMenu.xib文件.

1 ) add a MainMenu to your MainMenu.xib file.

即使主菜单不会显示(因为您仅在执行NSStatusBar项)，您还是希望该主菜单是由于编辑"菜单中的命令键(例如，用于拦截 cmd的东西 -X， cmd -C和 cmd -V).无论第一响应者是谁，这些命令键都会发送到您的文本字段或Web视图.

Even though the main menu won't display (because you're only doing a NSStatusBar item), you want that main menu because of the command keys in the Edit menu (i.e. something to intercept the cmd-X, cmd-C & cmd-V's). Those command keys will be sent to your text field or your webview, whatever is the first responder.

2)

我通过添加以下内容使您的文本字段成为第一响应者:

I made your textfield the first responder by adding:

- (void)viewDidAppear
{
    [super viewDidAppear];
    [self.textField becomeFirstResponder];
}

到您的ViewController.m文件.

to your ViewController.m file.

3)

您还需要将状态项"弹出的窗口设置为关键窗口.在示例应用程序中，确实有一个注释掉的canBecomeKeyWindow方法.我取消注释并始终返回TRUE.

You also need to make the window brought up by the Status Item a key window. In your example app, you did have a commented out canBecomeKeyWindow method. I uncommented it out and always return TRUE.
