如何在OS X中为我的文档创建图标 [英] How do I create icon for my documents in OS X

问题描述

我有一个基于文档的应用程序.因此，我需要为我的应用程序提供一个图标，并为我的文档提供一个图标.

I have a document-based application. So I need an icon for my app as well as an icon for my documents.

在Xcode/Images.xcassets中，有一个名为AppIcon的项目，我可以使用它来设置应用程序的图标.

In Xcode/Images.xcassets there is an item called AppIcon which I can use for setting the icon of the app.

但是如何为我的文档制作图标?

But how do I make an icon for my documents?

这是我在TARGETS/文档类型和TARGETS/导出的UTI下尝试过的内容

Here is what I have tried under TARGETS/Document Types and TARGETS/Exported UTIs

我尝试了Internet上建议的其他方法，但是没有任何效果.文档图标始终为空，如下所示:

I have tried different methods suggested on Internet but nothing works. The doc icon is always blank and empty as you can see below:

推荐答案

事实证明，如果更改图标，则也必须更改扩展名才能显示图标.

It turns out that if you change your icon you have to change the extension as well in order for the icon to show up.

所以我要做的是先测试没有任何图标变成空白图标，然后再尝试添加真实图标.那没有用.相反，添加新图标后，还请确保更改扩展名.

So what I did was to first test without any icon getting an empty icon, and then tried to add the real icon. That did not work. Instead as soon as you add a new icon, also make sure to change the extension.

可笑的是，这么小的事情怎么会让你整日迷失，而且我什至没有在网上找到任何暗示.

It is funny how such a little thing can make you lose a whole day, and also that I didn't find even a hint on this on the net.
