大佬教程收集整理的这篇文章主要介绍了objective-c – NSOutlineView：编辑绑定到NSTreeController的NSTextFieldCell时的异常，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
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.%@",@L_675_1@data.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.

我想绑定适用于显示值,但不能编辑它们？
updatE
我添加了@L_944_33@符号断点,我得到以下内容：
po *(id *)($esp + 4) <NSTextValueBinder: 0xfe40720>{object: <NSTablecolumn: 0xfe40180> identifier: MovieReleaseYear,bindings: value=arrangedObjects.MovieReleaseYear} p *(SEL *)($esp + 8) (SEL) $10 = "_valueForKeyPath:ofObject:mode:raisesForNotApplicableKeys:" po *(id *)($esp + 12) arrangedObjects po *(id *)($esp + 16) <CBTreeController: 0x39b4340>[object class: NSMutableDictionary]
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@L_944_33@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.%@",@L_675_1@data.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.%@",@L_675_1@data.columnBindingKeyPath] options:bindingOptions];
