我喜欢以编程方式创建我的界面。 / p>

I would prefer to create my interfaces programatically.

为什么？ Interface Builder更容易，更快。你不能通过拖放来写错字，当你用手打字矩形时，你不会得到那些非常方便的Aqua指南。

Why? Interface Builder is easier and faster. You can't write a typo by drag and drop, and you don't get those oh-so-handy Aqua guides when you're typing rectangles by hand.

不要打它。 Interface Builder是您的朋友。让它帮助你。

Don't fight it. Interface Builder is your friend. Let it help you.

如果你坚持通过在代码中编写你的UI浪费你自己的时间和精力：

If you insist on wasting your own time and energy by writing your UI in code:

不是基于文档的（通常基于库的，如邮件，iTunes，iPhoto）：创建NSObject的子类，实例化它，并将其作为应用程序的委托，并在委托的 applicationDidFinishLaunching：方法，创建一个窗口，用视图填充它，然后排序。

Not document-based (generally library-based, like Mail, iTunes, iPhoto): Create a subclass of NSObject, instantiate it, and make it the application's delegate, and in the delegate's applicationDidFinishLaunching: method, create a window, populate it with views, and order it front.

基于文档Preview，QuickTime Player）：在NSDocument子类中的 makeWindowControllers 方法中，创建你的窗口（并用视图填充它们）并为它们创建窗口控制器，确保发送 addWindowController：。

Document-based (like TextEdit, Preview, QuickTime Player): In the makeWindowControllers method in your subclass of NSDocument, create your windows (and populate them with views) and create window controllers for them, making sure to send yourself addWindowController: for each window controller.
