将NSTabViewItem中的NSTabViewItem副本添加到同一NSTabView中 [英] Adding a copy of an NSTabViewItem from an NSTabView into the same NSTabView

问题描述

我正在创建一个简单的Web浏览器，并希望实现标签页.为此，我正在使用 NSTabView .我基本上希望每个选项卡都有一个 WebView 来显示已加载的网站.我仅从一个选项卡开始，并希望在创建新选项卡时添加第一个选项卡的精确副本.我尝试了类似 tabView.addTabViewItem(tabView.tabViewItemAtIndex(0).copy()as NSTableViewItem)之类的东西，但是却收到了无法识别的选择器发送到实例的错误.我已经查看了 NSTableView 和 NSTableViewItem 的文档，但不知道该怎么做.

I'm creating a simple web browser and would like to implement tabs. For this purpose, I'm using an NSTabView. I basically want each tab to have a WebView that will show the website loaded. I'm starting with only one tab and want to add an exact copy of the first one when I create a new tab. I tried something like tabView.addTabViewItem(tabView.tabViewItemAtIndex(0).copy() as NSTableViewItem) but I'm getting an unrecognised selector sent to instance error. I've check the documentation for both NSTableView and NSTableViewItem but can't figure out how to that.

编辑我的整个错误看起来像这样:

EDIT My whole error looks like this:

015-03-14 17:15:57.884 Browser[1955:56547] -[NSTabViewItem copyWithZone:]: unrecognized selector sent to instance 0x600000100b40

感谢

Thanks to the answer on Copy NSView in cocoa and @MattyAyOh, I solved my problem by doing:

var data = NSKeyedArchiver.archivedDataWithRootObject(view)
var newView = NSKeyedUnarchiver.unarchiveObjectWithData(data) as NSView
newTab.view = newView
tabView.addTabViewItem(newTab)
