You don't have to, although it would make things easier. You need to extract the data from your XML file; take a look at the NSXMLDocument documentation, and the documentation for its superclass, NSXMLNode; these classes make it fairly easy to retrieve different "nodes" from your XML, and place them into an array. From there, it is easy to retrieve their string values, add this information to your NSPopupButton instance:
你没必要,虽然它会让事情变得更容易。您需要从XML文件中提取数据;看一下NSXMLDocument文档,以及它的超类NSXMLNode的文档;这些类使得从XML中检索不同的“节点”变得相当容易,并将它们放入数组中。从那里,可以轻松检索其字符串值,将此信息添加到NSPopupButton实例:
[popUpButton addItemsWithTitles:objects];
Where objects is an NSArray (or NSMutableArray) containing the titles of the items you want to add to the pop up button, and popUpButton is the pointer to your NSPopUpButton instance.
其中objects是一个NSArray(或NSMutableArray),其中包含要添加到弹出按钮的项的标题,popUpButton是指向NSPopUpButton实例的指针。
