当我在NSOutlineView中编辑NSTextFieldCell(在我点击后立即开始闪烁)时,我遇到了崩溃.
表列绑定到数据源.这些值在单元格中正确显示,绑定有效,只有在编辑单元格时才会出现问题.
[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@",Metadata.columnBindingKeyPath] options:bindingOptions];
这是我得到的例外.似乎NSTextFieldCell是从NSControllerTreeProxy设置/获取值而不是NSTreeController的内容.

解决方法
我最近偶然发现了和你一样的问题.我不确定是否要帮助你,但我仍然会提供适合我的修复方法.
我不知道你的整个代码,所以我不能确定它是否和你一样,但我也是,试图绑定一个列并稍后编辑它,给我同样的崩溃.
事实上这很简单.我在将列添加到Outline视图之前绑定了列,如下所示：
[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@",Metadata.columnBindingKeyPath] options:bindingOptions]; [theOutlineView addTableColumn: theEditingColumn]
我无法解释为什么会出现这种情况,但转换它就把它固定在我身边：
[theOutlineView addTableColumn: theEditingColumn] [theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@",Metadata.columnBindingKeyPath] options:bindingOptions];
