objective-c - 如何在 cocoa 中创建 "Choose Dialog"？

Question

在 Apple 人机界面指南中，有一个关于 Choose Dialogs 的部分，与打开对话框不同:

By default, the dialog’s title is “Choose.” If, for example, the command that displays the dialog is Choose Picture, title the dialog “Choose Picture.” If it’s helpful, also change the Choose button to something more specific.

但是，我无法找到任何有关如何创建一个文档，而不是常规的 NSOpenPanel。

Answer 1

尝试以下操作:

NSOpenPanel *openPanel=[NSOpenPanel openPanel];
[openPanel setTitle: @"Choose File"];
[openPanel setPrompt: @"Choose"];
[openPanel setCanChooseDirectories: YES];
[openPanel setCanChooseFiles: NO];
if ([openPanel runModal] != NSCancelButton)
    {
    // Use -[openPanel URL]...
    }
