Question

我有一个可在多个OS X版本上使用的应用程序。只有某些操作系统版本的用户可以使用NSToolbarItem的最佳方法是什么。当它不可用时，它应该被完全隐藏，而不仅仅是禁用。

为了简化，如何以编程方式从此（下方）菜单中删除工具栏项？

Toolbar Customization

修改：我试图在代理中覆盖toolbarAllowedItemIdentifiers:，如下所示：

- (NSArray *)toolbarAllowedItemIdentifiers:(NSToolbar *)toolbar {
    NSLog(@"Toolbar requesting allowed items.");
    NSMutableArray *array = [NSMutableArray array];
    [array addObject:@"TPUpToolbarItem"];
    [array addObject:@"TPDownToolbarItem"];
    [array addObject:@"TPResetToolbarItem"];
    [array addObject:@"TPSpeedToolbarItem"];
    [array addObject:@"TPGroupToolbarItem"];
    [array addObject:@"TPBackgroundToolbarItem"];
    [array addObject:NSToolbarShowFontsItemIdentifier];
    if (floor(NSAppKitVersionNumber) <= 1038) {
        NSLog(@"Below Lion, adding Fullscreen item.");
        [array addObject:@"TPFSToolbarItem"];
    }
    [array addObject:@"TPFlipHToolbarItem"];
    [array addObject:@"TPFlipVToolbarItem"];
    [array addObject:NSToolbarFlexibleSpaceItemIdentifier];
    [array addObject:NSToolbarSpaceItemIdentifier];
    [array addObject:NSToolbarSeparatorItemIdentifier];
    [array addObject:NSToolbarShowColorsItemIdentifier];
    [array addObject:NSToolbarPrintItemIdentifier];
    return array;
}

所有其他工具栏项目都以正确的顺序显示，但全屏项目是最后一项，并且仍在那里。

提前致谢。

除了-toolbarDefaultItemIdentifiers:之外，别忘了-toolbarAllowedItemIdentifiers:。尝试以下内容：

enum {
    MDUndeterminedVersion    = 0,
    MDTiger                  = 0x1040,
    MDLeopard                = 0x1050,
    MDSnowLeopard            = 0x1060,
    MDLion                   = 0x1070,
    MDMountainLion           = 0x1080,
    MDMavericks              = 0x1090,
    MDUnknownVersion         = 0x1100 // ??
};

static SInt32 MDSystemVersion = MDUndeterminedVersion;

+ (void)initialize {
    if (MDSystemVersion == MDUndeterminedVersion) {
        SInt32 MDFullSystemVersion = 0;
        Gestalt(gestaltSystemVersion, &MDFullSystemVersion);
        MDSystemVersion = MDFullSystemVersion & 0xfffffff0;
    }
}

- (NSArray *)toolbarAllowedItemIdentifiers:(NSToolbar *)toolbar {
    NSLog(@"Toolbar requesting allowed items.");
    NSMutableArray *array = [NSMutableArray array];
    [array addObject:@"TPUpToolbarItem"];
    [array addObject:@"TPDownToolbarItem"];
    [array addObject:@"TPResetToolbarItem"];
    [array addObject:@"TPSpeedToolbarItem"];
    [array addObject:@"TPGroupToolbarItem"];
    [array addObject:@"TPBackgroundToolbarItem"];
    [array addObject:NSToolbarShowFontsItemIdentifier];
    if (MDSystemVersion < MDLion) {
        NSLog(@"Below Lion, adding Fullscreen item.");
        [array addObject:@"TPFSToolbarItem"];
    }
    [array addObject:@"TPFlipHToolbarItem"];
    [array addObject:@"TPFlipVToolbarItem"];
    [array addObject:NSToolbarFlexibleSpaceItemIdentifier];
    [array addObject:NSToolbarSpaceItemIdentifier];
    [array addObject:NSToolbarSeparatorItemIdentifier];
    [array addObject:NSToolbarShowColorsItemIdentifier];
    [array addObject:NSToolbarPrintItemIdentifier];
    return array;
}

-

- (NSArray *)toolbarDefaultItemIdentifiers:(NSToolbar *)toolbar {
    NSLog(@"Toolbar requesting default items.");
    NSMutableArray *array = [NSMutableArray array];
    [array addObject:@"TPUpToolbarItem"];
    [array addObject:@"TPDownToolbarItem"];
    [array addObject:@"TPResetToolbarItem"];
    [array addObject:@"TPSpeedToolbarItem"];
    [array addObject:@"TPGroupToolbarItem"];
    [array addObject:@"TPBackgroundToolbarItem"];
    [array addObject:NSToolbarShowFontsItemIdentifier];
    if (MDSystemVersion < MDLion) {
        NSLog(@"Below Lion, adding Fullscreen item.");
        [array addObject:@"TPFSToolbarItem"];
    }
    [array addObject:@"TPFlipHToolbarItem"];
    [array addObject:@"TPFlipVToolbarItem"];
    [array addObject:NSToolbarFlexibleSpaceItemIdentifier];
    [array addObject:NSToolbarSpaceItemIdentifier];
    [array addObject:NSToolbarSeparatorItemIdentifier];
    [array addObject:NSToolbarShowColorsItemIdentifier];
    [array addObject:NSToolbarPrintItemIdentifier];
    return array;
}

请注意，如果您允许为工具栏设置用户自定义，则可能需要删除apps pref文件以注意工具栏设置中的更改。

使用Gestalt。

@NSGod几乎就在那里。当他的其余代码工作时，看起来IB正在覆盖我的代码并且无论如何都要添加全屏按钮。我必须将工具栏项移出工具栏，然后通过添加此方法手动将NSToolbarDelegate指向它：（up，down等等IBOutlet s ）

- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar itemForItemIdentifier:(NSString *)itemIdentifier willBeInsertedIntoToolbar:(BOOL)flag {
    if ([itemIdentifier isEqualToString:@"TPUpToolbarItem"]) {
        return up;
    }
    if ([itemIdentifier isEqualToString:@"TPDownToolbarItem"]) {
        return down;
    }

    if ([itemIdentifier isEqualToString:@"TPResetToolbarItem"]) {
        return reset;
    }
    if ([itemIdentifier isEqualToString:NSToolbarShowColorsItemIdentifier]) {
        return colors;
    }
    if ([itemIdentifier isEqualToString:NSToolbarShowFontsItemIdentifier]) {
        return fonts;
    }
    if ([itemIdentifier isEqualToString:NSToolbarPrintItemIdentifier]) {
        return print;
    }
    if ([itemIdentifier isEqualToString:@"TPSpeedToolbarItem"]) {
        return speed;
    }
    if ([itemIdentifier isEqualToString:@"TPBackgroundToolbarItem"]) {
        return background;
    }
    if ([itemIdentifier isEqualToString:@"TPGroupToolbarItem"]) {
        return group;
    }
    if ([itemIdentifier isEqualToString:NSToolbarFlexibleSpaceItemIdentifier]) {
        return flex;
    }
    if ([itemIdentifier isEqualToString:NSToolbarSpaceItemIdentifier]) {
        return space;
    }
    if ([itemIdentifier isEqualToString:@"TPFlipHToolbarItem"]) {
        return flipH;
    }
    if ([itemIdentifier isEqualToString:@"TPFlipVToolbarItem"]) {
        return flipV;
    }
    if ([itemIdentifier isEqualToString:NSToolbarSeparatorItemIdentifier]) {
        return sep;
    }
    if ([itemIdentifier isEqualToString:@"TPFSToolbarItem"]) {
        return fsItem;
    }
}

NSToolbarItem基于OS X版本的可用性
