如何将自定义 UIButton 添加到 XCode 中的 nib 文件？
我刚刚开始深入研究 iOS 开发的世界。我也是 XCode 的新手。我现在使用可用的默认 UIComponents 构建了几个小测试应用程序，方法是将它们从对象库拖放到我的 .xib 文件上，然后连接插座和操作，只是为了看看它是如何工作的。我想进入下一步并创建我自己的自定义绘制按钮。我有一个名为 CustomButton 的类，它扩展了 UIButton，我可以以编程方式将其添加到视图中，但我想知道如何将其拖放到 nib 文件上，以便我可以直观地而不是以编程方式布局它。我知道这是一个初学者问题，但我整晚都在搜索，试图找到如何做到这一点的示例，但没有成功。非常感谢任何帮助。
I've just begin delving in to the world of iOS development. I am also a newbie to XCode. I've built several little test apps nows using the default UIComponents available by dragging and dropping them from the Objects library on to my .xib file and hooking up outlets and actions just to see how it all works. I wanted to take it to the next step and create my own custom painted button. I have a class named CustomButton that extends UIButton and I can programmatically add it to a view, but I would like to know how to drag and drop it on to a nib file so I can lay it out visually rather than programmatically. I know this is a beginner question but I've searched all night trying to find an example of how to do it with no success. Any help is greatly appreciated.

将 UIView 放入笔尖并将其自定义类设置为 UIButton 子类。
Drop in a UIView into your nib and set its Custom Class to your UIButton subclass.
