绑定到 NSMatrix 以获得 BOOL 属性
我有一个简单的核心数据实体，它有一个名为 subscribedToNewsletter 的布尔属性。我设计了我的 UI，将此字段表示为单选按钮组，其中 Yes/No 作为文本值（显然 YES/NO 作为支持 BOOL 值）。
我一直认为自己拥有出色的谷歌功能，但在我的一生中，我无法找到任何明确的文档：
- 如何将 NSMatrix 的选定值（或者是单元格？）绑定回 YES /NO value
- 如何绑定文本值（如果我确实需要的话；我知道只会有两个值 - 当然它们可以在 Interface Builder 中硬编码，或者不是？）
接下来将是如何将单选组（带有 Male/Female 文本）绑定到名为 gender 的字符串字段，该字段具有 M 和 F作为可能的值 - 但我离题了。
任何指示将不胜感激。多谢。
I have a simple core-data entity that has a Boolean attribute called subscribedToNewsletter. I have designed my UI to represent this field as a radio button group with Yes/No as the text values (and obviously YES/NO as the backing BOOL values).
I have always considered myself to have excellent google-fu, but for the life of me, I am unable to find any clear documentation on:
- how to bind the selected value of the NSMatrix (or is it the cell?) back to a YES/NO value
- how to bind the textual values (if indeed I do need to; I know there are only ever going to be two values - surely they can be hard-coded in Interface Builder, or not?)
Next up will be how to bind a radio group (with Male/Female text) to a String field called gender that has M and F as possible values - but I digress.
Any pointers would be very much appreciated. Thanks a lot.

不确定我是否没有得到答案，因为a）这是一个愚蠢的问题，或者b）世界上没有人知道怎么做。后者对我来说不太可能，所以我只能假设第一个:)
无论如何，以防万一其他人像我一样愚蠢，我想我会就我如何实现它提供一些反馈。
在 Interface Builder 中，我创建了一个 NSMatrix，其中包含两个单选按钮单元格，其中每个单元格的文本分别为“是”和“否”。在属性检查器 (command-1) 中，确保“是”按钮单元的“标签”字段设置为 1，“否”按钮单元的“标签”字段设置为 0。然后，在绑定检查器 (command-4) 中，将矩阵 的 SelectedTag 字段绑定到实体上的布尔属性。简单如馅饼。
我并不声称这是最好的方法......只是它是有效的。
Not sure if I got no answers because a) it is such a stupid question, or b) no-one in the world knows how. The latter doesn't strike me as likely, so I can only presume the first :)
Anyway just in case there others as stupid as me, I thought I'd give some feedback on how I managed to achieve it.
In Interface Builder, I created a NSMatrix with two radio button cells with "Yes" and "No" as the text for each respectively. In the Attributes Inspector (command-1), make sure the Tag field is set to 1 for the "Yes" button cell, and set to 0 for the "No" button cell. Then, in the Bindings Inspector (command-4) bind the SelectedTag field for the matrix to the Boolean property on your entity. Easy as pie.
I make no claims that this is the best way... just that it is effective.
