基于NSOutlineView单元的从fieldEditor获取列

Question

我有一个基于outlineView单元格的旧项目，如果其中一个单元格在"outlinView setObjectValue:“get之前的值不正确，我想要创建一个outlinView。我需要知道地点在哪里，我尝试过的是这样的成功：

- (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText *)fieldEditor
{
    if ([control isEqualTo: myOutline]) {
        id item = [myOutline itemAtRow:[myOutline selectedRow]]; // ok
        NSInteger columnNum = [myOutline columnForView:fieldEditor];
        NSLog(@"columnNum = %ld", (long) columnNum); // bad, wrong column, it print 0 but the cell is at column 3
        TreeObj *data = (TreeObj *)[item representedObject];
        // .... rest of the code, return NO if the value is not correct ..

    }
    return YES;
}

"fieldEditor“似乎不利于找到正确的列，因为..its superview不是..its (??)所期望的。感谢您的建议，并随时发布快速代码。

(编辑)从@Willeke接受的更正代码：

- (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText *)fieldEditor
{
    if ([control isEqualTo: myOutline]) {
        id item = [myOutline itemAtRow:[myOutline selectedRow]]; // ok
        NSTableColumn *tableCoumn = [[myOutline tableColumns] objectAtIndex:[myOutline editedColumn]];
        TreeObj *data = (TreeObj *)[item representedObject];
        if ([tableCoumn.identifier isEqualToString:@"theRightColumn"]) {
            // .... rest of the code, return NO if the value is not correct and display the alert..
        }


    }
    return YES;
}

编辑的行和列是属性editedRow和editedColumn of NSTableView，NSOutlineView的超类。您要查找的列是[myOutline editedColumn]或myOutline.editedColumn。
