我只有一个主从类型的应用程序 OS X 10.9:
窗口左侧的 NSTableView,右侧的详细信息为 NSTextFields。
我没有专门设置标签顺序,开箱即用就可以了。
插入新对象后除外:
- 插入新对象后,该对象在 NSTableView 中被选中。
- 点击标签
- 第一个 NSTextField 被选中
- 写点东西,点击标签
- 现在没有选择下一个 NSTextField 而不是选择任何内容,
- 点击标签
- NSTableView 被选中
- 点击标签
- 第一个 NSTextField 被选中
我想要的是:
- 插入新对象后,应该选择detail部分的第一个NSTextField
- 点击标签
- 应该选择详细部分的下一个 NSTextField
- …</li>
更新:我发现奇怪的行为是通过在 Interface Builder 中启用 NSArrayController 的“自动重新排列内容”来触发的。如果我禁用它,我不会再失去焦点。请参阅CoreData-bound NSTableView 在项目更改时失去输入焦点,但前提是排序。
但是,当然,我仍然希望我的内容能够自动排序——只是在操作过程中不会失去我的注意力。这可以做到吗?
UPDATE2:当我的文本字段失去键盘焦点时,我遵循了@KenThomases 的建议并记录了堆栈跟踪:

所以也许我可以编写自己的 NSArrayController rerangeObjects: 方法,这样不会失去焦点?
