在自定义视图中添加按钮的NSMatrix（NSRadioModeMatrix），设置目标/操作

Question

我是NSTabView的子类，以自定义外观。我想使用NSBatonCells的NSMatrix来选择选项卡。我设法在我的NSTabView子类的initWithFrame：方法中添加带有按钮的NSMatrix。我无法工作的是以编程方式设置目标和操作。这是我试过的：

定义TAB_WIDTH 24.0f

定义TAB_HEIGHT 24.0f

- (id)initWithFrame:(NSRect)frameRect
{
    self = [super initWithFrame:frameRect];

    if (self) {

        NSInteger numberOfTabs = 5;
        NSInteger tabSpacing = 8;

        NSSize cellSize = NSMakeSize(TAB_WIDTH, TAB_HEIGHT);
        NSSize interCellSpacing = NSMakeSize(tabSpacing, 0);

        CGFloat tabSelectorWidth = TAB_WIDTH * numberOfTabs + tabSpacing * numberOfTabs - 1;
        CGFloat xOrigin = (frameRect.size.width - tabSelectorWidth) / 2;

        NSRect tabSelectorFrame = NSMakeRect(xOrigin, 0, tabSelectorWidth, TAB_HEIGHT);

        NSButtonCell *cellPrototype = [[NSButtonCell alloc] init];

        [cellPrototype setBordered:NO];

        _tabSelector = [[NSMatrix alloc] initWithFrame:tabSelectorFrame
                                                  mode:NSRadioModeMatrix
                                             prototype:cellPrototype
                                          numberOfRows:1
                                       numberOfColumns:5];

        [_tabSelector setTarget:self];
        [_tabSelector setAction:@selector(selectedTab)];

        [_tabSelector setCellSize:cellSize];
        [_tabSelector setIntercellSpacing:interCellSpacing];

        NSArray *theCells = [_tabSelector cells];

        [theCells[0] setImage:[NSImage imageNamed:@"tab1"]];
        [theCells[1] setImage:[NSImage imageNamed:@"tab2"]];
        [theCells[2] setImage:[NSImage imageNamed:@"tab3"]];
        [theCells[3] setImage:[NSImage imageNamed:@"tab4"]];
        [theCells[4] setImage:[NSImage imageNamed:@"tab5"]];

        [self addSubview:_tabSelector];

        [self setDrawsBackground:NO];
        [self setTabViewType:NSNoTabsNoBorder];
    }

    return self;
}

- (void)selectTab:(NSMatrix *)sender
{
    NSLog(@"selected tab");
}

视图是根据需要绘制的，但单击按钮不会调用目标方法。

我尝试以编程方式将按钮添加到标准IB视图中，如Programatically create and position an NSButton in an OS X app?

所述

这很有效，但在我的自定义视图中，事情就崩溃了。任何人都能给我一个暗示我缺少的东西吗？

尝试更改

 `   [_tabSelector setAction:@selector(selectedTab)];`

要

 `   [_tabSelector setAction:@selector(selectedTab:)];`
