发送了无法识别的选择器？
我一直在使用 MonoTouch 和 Xcode 界面构建器，从一些已经定义了界面的示例代码中进行修改。
添加按钮并为其提供单击回调后，我发现其中一个按钮不再响应单击，而是崩溃了：
2011-09-30 01:51:35.361 RedLaserSample[19437:707] -[RLSampleViewController scanPressed]：发送到的无法识别的选择器 实例0x17e1260 MonoTouch.Foundation.MonoTouchException： Objective-C 抛出异常。名称： NSInvalidArgumentException 原因：-[RLSampleViewController scanPressed]：无法识别的选择器 发送到 MonoTouch.UIKit.UIApplication.Main 处的实例 0x17e1260 (System.String[] args, System.StringprincipalClassName, System.String delegateClassName) [0x00000] 在 :0 处 RedLaserSample.Application.Main (System.String[] args) [0x00000] 在 /Users/dev/Desktop/chrisbranson-RedLaserSample-0311fa6/RedLaserSample/Main.cs:28
有什么想法可能导致此问题以及如何修复它吗？
I've been mucking around with MonoTouch and the Xcode interface builder from some sample code which had an interface defined already.
After adding a button and giving it a click callback I found one of the buttons was no longer responding to clicks and instead crashing out:
2011-09-30 01:51:35.361 RedLaserSample[19437:707]
-[RLSampleViewController scanPressed]: unrecognized selector sent to
instance 0x17e1260 MonoTouch.Foundation.MonoTouchException:
Objective-C exception thrown. Name: NSInvalidArgumentException
Reason: -[RLSampleViewController scanPressed]: unrecognized selector

(System.String[] args, System.String principalClassName, System.String
delegateClassName) [0x00000] in :0 at
RedLaserSample.Application.Main (System.String[] args) [0x00000] in
/Users/dev/Desktop/chrisbranson-RedLaserSample-0311fa6/RedLaserSample/Main.cs:28
Any ideas what could be causing this and how I could fix it?

解决了这个问题，出于某种原因，我必须在 Xcode 构建器中重新添加单击事件。也许当添加添加按钮回调的新方法时，使用旧版本的 mono 构建的项目会自行崩溃？
Solved it, for some reason I had to re-add the click event in the Xcode builder.. perhaps the project being built with an older version of mono broke itself when a newer way of adding button callbacks was added in?
