该方法应该进入与 XIB（发音为 NIB）文件关联的控制器中。在该控制器的标头中，您将声明一个方法，例如
-(IBAction) userPressedButton:(id) sender;
保存 .h，然后返回 InterfaceBuilder，选择按钮并按 cmd-2 显示插座检查器。将“Touch Up Inside”拖至图标计数窗口中的“文件所有者”。该 FileOwner 对象是您的控制器。当您放开时，它将弹出控制器中所有操作的菜单，因此您应该看到 userPressedButton 方法。单击该按钮。
然后在实现 (.m) 文件中，您可以实现该方法来执行您想要的任何操作，例如显示 AlertView 等。基本上，XIB 的文件所有者是控制器类，并且您刚刚告诉 IB，当手指被在按钮区域内抬起，它应该调用 userPressedButton 方法。
简单 ;-) 开始时很奇怪，然后就很棒了。
The method should go in the controller associated with XIB (pronounced NIB) file. In the header of that controller you will declare a method such as
-(IBAction) userPressedButton:(id) sender;
Save the .h, and return to InterfaceBuilder, select your button and press cmd-2 to show the inspector for outlets. Drag "Touch Up Inside" to File Owner in the window countaining the icons. That FileOwner object is your controller. When you let go it will pop-up a menu of all of the Actions in the controller, so you should see your userPressedButton method. Click that.
Then in the implementation (.m) file you, well, implement that method to do whatever you want such as display an AlertView etc. Basically the XIB's file owner is the controller class, and you've just told IB that when a finger is lifted up inside the area of your button, it should call the userPressedButton method.
Simples ;-) It's strange to start with, then wonderful.
