cocoa - 具有 2 列、文本和检查的 NSOutlineView

Question

我已经这样做了：

那是具有两列的 NSOutlineView，第一列是 TextCell，在第二列上我拖放复选框单元格。现在，我将所有行设置为 true：

-(id)outlineView:(NSOutlineView *)outlineView objectValueForTableColumn:(NSTableColumn *) tableColumn byItem:(id)item {
    if ([[tableColumn identifier] isEqualToString:@"name"]) {
        返回[项目名称]；
    } else if ([[tableColumn identifier] isEqualToString:@"sel"]) {
        返回@“1”；//对于NSOnState
                //返回@“0”；//对于 NSOffState
    }
}

现在我希望当用户单击复选框时它转到 NSOffState 并且我尝试内部方法：

-(void)outlineView:(NSOutlineView *)outlineView setObjectValue:(id)object forTableColumn:(NSTableColumn *)tableColumn byItem:(id)item {

    [项目 setSel:NSOffState];
}

但它不去，我该怎么办？

帮我 ！！！

    @interface AppDelegate : NSObject {
        NSMutableArray *array;
    }

    @property (assign) IBOutlet NSWindow *window;

    #import "AppDelegate.h"

    @implementation AppDelegate

    @synthesize 窗口 = _window;

    - (void)dealloc

        布尔测试=是；
        NSNumber *num=[NSNumber numberWithBool:test];

        [dc setObject:num forKey:@"sel"];
        [dc setObject:@"name" forKey:@"name"];

        [数组添加对象：dc]；
    //[self setArray:self.array];
     }

     - (id)outlineView:(NSOutlineView *)outlineView child:(NSInteger)index ofItem:(id)item
