Monotouch 4:应用程序在 iPhone 设备上启动时崩溃，可在模拟器上运行 [英] Monotouch 4: App crash on launch on iPhone device, works on simulator

问题描述

我的设置是:

• MonoDevelop 2.8.5
• MonoTouch 4.0.6
• XCode 4.2

我创建了一个单视图 iphone 项目.在模拟器和设备上构建这个都可以.

I create a Single-view iphone project. Building this works on both simulator and device.

现在我双击 .xib 文件，在 XCode 中添加一个文本字段并创建一个出口.没有写其他代码.

Now I double click the .xib file, add a Textfield in XCode and create an outlet. No other code written.

在模拟器上运行这个效果很好.在任何 iPhone 设备上运行它都会在启动时崩溃.我设法获得以下堆栈跟踪:

Running this on the simulator works perfectly. Running it on any iPhone device crashes on launch. I managed to get the following stack trace:

System.NullReferenceException: Object reference not set to an instance of an object

有人提到 MonotTouch 4 仅适用于 MonoDevelop 2.6.问题是自从模拟器工作以来，我已经在 MD 2.8.5 中编写了很多代码，当我回滚到 MD 2.6 时，项目将无法加载...

Somebody mentioned that MonotTouch 4 only works with MonoDevelop 2.6. The problem is that I have already written a lot of code in MD 2.8.5 since the simulator was working, and when I roll back to MD 2.6 the project will not load...

推荐答案

您在 XIB 文件中有一个出口，该出口未映射到 C# 中控制器中的属性.这就是美妙的 class is not key value coding-compatible 消息所表明的.这是一个链接.

You have an outlet in a XIB file that isn't mapped to a property in your controller in C#. This is what the wonderful class is not key value coding-compliant message indicates. Here is a link.

我建议您获取最新的 MonoTouch/MonoDevelop(非测试版)和 XCode，然后查找您拥有的插座并查看哪个插座未正确连接.

I would recommend getting the latest MonoTouch/MonoDevelop (non-beta) and XCode, then find what outlets you have and see which one is not hooked up properly.

如果 XCode 不为你做，你可以手动设置它们，有一个简单的 [Outlet] 属性，你把它放在插座的属性上.查看 *.designer.cs 文件以获取示例.

You can manually set them up if XCode won't do it for you, there is a simple [Outlet] attribute you put on properties for outlets. Look at a *.designer.cs file for examples.
