升级到 Monotouch 4.0 后 MissingMethodException
有人使用优秀的 Sparrow 2D monotouch 库吗？
https://github.com/trustme/Sparrow
我刚刚更新到 Monotouch 4.0 和 Monodevelop 2.4.2，当 重建并运行 SparrowTest 给了我这个奇怪的错误：
System.MissingMethodException has been thrown "Method not found:
'Monotouch.ObjCRuntime.Messaging.void_objc_msgSend_Boolean'." at
SparrowTest.AppDelegateIPhone.FinishedLaunching in
AppDelegateIPhone.cs:23
方法是：
SPStage.SupportHighResolutions = true;
当评论时，它在许多其他方法上给出了相同的错误。我已经 尝试使用不同的sdk版本，但问题仍然存在。
有什么线索吗？
Does anyone use the excellent Sparrow 2D monotouch library?
https://github.com/trustme/Sparrow
I just updated to Monotouch 4.0 and Monodevelop 2.4.2, and when
rebuilt and run SparrowTest gives me this strange error:
System.MissingMethodException has been thrown "Method not found:
'Monotouch.ObjCRuntime.Messaging.void_objc_msgSend_Boolean'." at
SparrowTest.AppDelegateIPhone.FinishedLaunching in
AppDelegateIPhone.cs:23
The method is:
SPStage.SupportHighResolutions = true;
When commented it gives the same error on many other methods. I've
tried using different sdk versions but the problem persists.
Any clues?

您需要使用 btouch 为 MonoTouch 4 重新生成 sparrow.dll。
You need to regenerate the sparrow.dll with btouch for MonoTouch 4.
尝试创建带有 -out 的脚本来重新生成第三方库
避免此问题的另一种方法是在项目的构建输出中选择：不要链接程序集
你的项目将会成功
try to create a script with -out to regenerate Third Part Libraries
another way to avoid this problem, is that inm your build output of your project choose : Don't link the assemblies
and your project will work
问题解决了！
对于 MonoTouch 4.0，我们必须使用 smcs 而不是 gmcs。
以下是使用 MonoTouch 4.0 生成 sparrow.dll 的正确过程，分两步：
/Developer/MonoTouch/usr/bin/btouch sparrow.cs -s:enum.cs --outdir=gen -ns=Sparrow --unsafe - -sourceonly=genfiles
/Developer/MonoTouch/usr/bin/smcs -out:sparrow.dll
cat genfilesextensions.cs -unsafe -r:/Developer/MonoTouch/usr/lib/mono/2.1/ monotouch.dll enum.cs -target:library感谢 Geoff Norton 和 Duane Wandless 的帮助！
Problem solved!
With MonoTouch 4.0 we must use smcs instead of gmcs.
Here is the right procedure for generating sparrow.dll with MonoTouch 4.0, in two steps:
/Developer/MonoTouch/usr/bin/btouch sparrow.cs -s:enum.cs --outdir=gen -ns=Sparrow --unsafe --sourceonly=genfiles
/Developer/MonoTouch/usr/bin/smcs -out:sparrow.dll
cat genfilesextensions.cs -unsafe -r:/Developer/MonoTouch/usr/lib/mono/2.1/monotouch.dll enum.cs -target:libraryThanks to Geoff Norton and Duane Wandless for the help!
