在我的项目中,我有NSToolBar
,其中有NSToolBarItems
。我想删除最后两个toolbarItems,其中一个是NSToolbarSpaceItemIdentifier
,然后重新加载工具栏。
怎么做?
我被困在这一点上很长一段时间。如果我要从NSToolBar
中删除项目,我会因NSToolbarSpaceItemIdentifier
而收到约束警告。
我想再次回忆一下委托方法,并将最新的items数组传递给它。
怎么做?
请帮忙。

约束警告似乎是一个单独的问题 - 对于同一个项目,我们已经看到10.8但不低于10.9的这个错误 据我所知,这是一个框架错误,与API的任何错误用法无关。

我找不到一种方法来刷新。但杰伊是正确的,他的建议可以用来快速重置菜单
//Factory Method for reseting toolbar
func setCurrentToolBarItems(desiredItems:[String]){
// remove all toolbar items
for _ in (window?.toolbar?.items)!{
window?.toolbar?.removeItem(at: 0)
}
// add new items
for item in desiredItems{
window?.toolbar?.insertItem(withItemIdentifier: item, at: 0)
}
}
以下是一些以编程方式创建按钮的附加代码。
import Cocoa
class ToolbarWindowController: NSWindowController, NSToolbarDelegate {
@IBOutlet var DualToolBar: NSToolbar!
enum ToolbarItemID : String {
case DeleteCard = "DeleteSelectedCard", RandomizeCards = "RandomizeCards", CardTest = "CardTest",SwitchFirstCardFaceSeen = "SwitchFirstFace", ExitTest = "ExitTest"
static let allValues = [DeleteCard, RandomizeCards, CardTest, SwitchFirstCardFaceSeen, ExitTest]
}
override func windowDidLoad() {
super.windowDidLoad()
// Implement this method to handle any initialization after your window controller's window has been loaded from its nib file.
}
func test() {
contentViewController?.performSegue(withIdentifier: "goToSlideShow", sender: contentViewController)
setCurrentToolBarItems(desiredItems: [ToolbarItemID.RandomizeCards.rawValue, ToolbarItemID.SwitchFirstCardFaceSeen.rawValue])
}
//Factory Method for reseting toolbar
func setCurrentToolBarItems(desiredItems:[String]){
// remove all toolbar items
for _ in (window?.toolbar?.items)!{
window?.toolbar?.removeItem(at: 0)
}
// add new items
for item in desiredItems{
window?.toolbar?.insertItem(withItemIdentifier: item, at: 0)
}
}
// MARK: - NSToolbarDelegate

toolbarItem.label = label
toolbarItem.paletteLabel = paletteLabel
toolbarItem.toolTip = toolTip
toolbarItem.target = target
toolbarItem.action = action
toolbarItem.image = itemImage
return toolbarItem
