我有一个NSTableView,我想使用Interface Builder方法进行排序,而我在使用Apple Guides and Sample Code描述如何操作时遇到问题。基于对原始问题的评论,我认为这个文档太过时了,并且指向了错误的方向,所以我正在改写我的问题。
鉴于以下对默认Cocoa应用程序模板的添加:
class Foo: NSObject {
@objc dynamic var name : String
@objc dynamic var colour : String
override init() {
name = "name"
colour = "colour"
super.init()
}
init(_ name : String, _ colour : String) {
self.name = name
self.colour = colour
super.init()
}
}
class ViewController: NSViewController {
@objc dynamic var fooList : [Foo] = [Foo("Bar", "Red"),
Foo("Baz", "Green"),
Foo("Beelzebub", "Blue")]
}
我已在NSArrayController
的视图控制器中添加了NSTableview
和Main.storyboard
。阵列控制器"控制器内容"使用模型关键路径self.fooList
绑定到视图控制器,表格视图"表格内容"使用默认数据(arrangedObjects
的控制器密钥)和每个表视图单元"值"绑定到数组控制器。使用"模型密钥路径"绑定到表单元格视图。分别为objectValue.name
和objectValue.colour
。到目前为止,一切正常,我得到填充表格视图的数据。
根据评论中的建议,为了使列表可排序,我试图添加"排序描述符"绑定。我已经绑定了表格视图"排序描述符"到阵列控制器(默认选项)和阵列控制器对视图控制器的排序描述符(添加"模型键路径" self.fooList
)。
此时如果我尝试运行应用程序,我会得到一个例外和追溯:
