Webview 的 goToItem 没有做任何事情？
我目前正在尝试为我的浏览器设置一个漂亮的后退按钮上下文菜单。它使用 -backListWithLimit 提供的数组中的项目填充自身，并包含项目标题和图标。每个项目都将其representedObject 设置为其各自的WebHistoryItem，并将其操作设置为goToHistoryItem:，这是我的一个方法，它获取发送者的representedObject 并尝试告诉主webView 导航到该历史记录项。代码如下：
- (IBAction)goToHistoryItem:(id)sender
{
WebHistoryItem *historyItem = [sender representedObject];
[[mainWebView backForwardList] goToItem:historyItem];
}
菜单呈现完美，每个项目都有适当的标题和标记。但由于某种原因，选择一个项目根本就失败了。我已经检查过 NSLog，并且 WebHistoryItem 正在传递...... webView 不会用它做任何事情。它没有留下任何错误，没有控制台日志，什么都没有，而且我不知道哪里出了问题。
我在这里错过了什么吗？为什么这不起作用？
I'm currently trying to set up a nice back button contextual menu for my browser. It populates itself with items from the array provided by -backListWithLimit, complete with item titles and icons. Each item has its representedObject set to its respective WebHistoryItem and its action set to goToHistoryItem:, a method of mine which grabs the sender's representedObject and attempts to tell the main webView to navigate to that history item. Here's the code:
- (IBAction)goToHistoryItem:(id)sender
{
WebHistoryItem *historyItem = [sender representedObject];
[[mainWebView backForwardList] goToItem:historyItem];
}
The menu renders perfectly, with each item appropriately titled and badged. For some reason, though, selecting an item simply fails. I've checked with NSLog, and the WebHistoryItem IS getting passed along… the webView just won't do anything with it. It leaves no error, no console log, nothing, and I can't figure out where I've gone wrong.
Am I missing something here? Why doesn't this work?

好吧，我最终弄清楚了。结果我需要使用 [webView goToBackForwardItem:] 而不是 [[webView backForwardList] goToItem:]。
Well, I ended up figuring it out. Turns out I needed to use [webView goToBackForwardItem:] instead of [[webView backForwardList] goToItem:].
