NSTabView允许您指定一个对象作为其委托。该委托对象应该是符合NSTabViewDelegate协议的类的实例。除其他方法外，该协议还声明-tabView:willSelectTabViewItem:来通知委托将要选择选项卡项；-tabView:didSelectTabViewItem:通知委托已选择选项卡项。您可能想要实现
-tabView:willSelectTabViewItem:以便在选择该选项卡项之前填充字段。NSTabViewallows you to specify an object as its delegate. This delegate object should be an instance of a class that conforms to theNSTabViewDelegateprotocol. This protocol declares, amongst others methods,-tabView:willSelectTabViewItem:to inform the delegate that a tab item is about to be selected;-tabView:didSelectTabViewItem:to inform the delegate that a tab item has been selected.You probably want to implement
-tabView:willSelectTabViewItem:so that the fields are populated right before that tab item is selected.
