objective-c – 使NSOutlineView行可编辑

概述有没有人知道如何在NSOutlineView的可编辑中制作单元格？我使用苹果的样本代码,我似乎无法让它工作. 我正在设置它,以便当您在NSOutlineView中的单元格上快速连续单击两次时,单元格变为可编辑,以便用户可以更新单元格内的文本. (与xcode和邮件等工作方式相同). 我包含了这个控制器的大部分代码,徒劳地希望有人可以发现我做错了什么,这是非常令人沮丧的.我知道调用了theEditT 有没有人知道如何在NSOutlineVIEw的可编辑中制作单元格？我使用苹果的样本代码,我似乎无法让它工作.

我包含了这个控制器的大部分代码,徒劳地希望有人可以发现我做错了什么,这是非常令人沮丧的.我知道调用了theEdittableColumn,因为它在双击时返回NSLog消息.

解决方法 我知道这是一篇非常古老的帖子,但如果有人遇到同样的问题,这可能不是与代码相关的问题.对于我的情况,这是一个与XIB本身的值集相关的问题.

因此,假设您已经复制了所有Apple代码,并且您已经启动并运行了NSOutlineVIEw,以及一些仍然无法编辑的内容,请转到您的XIB并设置您想要的单元格的NSTextFIEld的以下设置编辑.在我的情况下,行为设置默认设置为none.也许对你来说也是同样的问题

干杯.
