我换了。Monotouch让我编写应用程序的速度至少提高了3-4倍(与我以前在Obj C中每月1个应用程序相比，每月4个)

打字少了很多。

只是我的经验。

使用Mono并不是一种依赖。它为iPhone操作系统增加了很多功能。LINQ, WCF, Silverlight应用程序之间的可共享代码，ASP。NET页面，一个WPF应用程序，一个Windows Form应用程序，还有针对Android的mono它也适用于Windows Mobile。

So, you can spend a bunch of time writing Objective-C (You'll see from many studies where the exact same sample code in C# is significantly less to write than OC) and then DUPLICATE it all for other platforms. For me, I chose MonoTouch because the Cloud App I'm writing will have many interfaces, the iPhone being only one of them. Having WCF data streaming from the cloud to MonoTouch app is insanely simple. I have core libraries that are shared among the various platforms and then only need to write a simple presentation layer for the iPhone/WinMobile/Android/SilverLight/WPF/ASP.NET deployments. Recreating it all in Objective-C would be an enormous waste of time both for initial dev and maintenance as the product continues to move forward since all functionality would have to be replicated rather than reused.

那些侮辱MonoTouch或暗示它的用户需要拐杖的人，是缺乏拥有。net框架的大蓝图，可能不理解逻辑与表示的正确分离，这种分离可以在跨平台和设备上重用。

Objective-C is interesting and very different from many common languages. I like a challenge and learning different approaches... but not when doing so impedes my progress or creates unnecessary re-coding. There are some really great things about the iPhone SDK framework, but all that greatness is fully supported with MonoTouch and cuts out all the manual memory management, reduces the amount of code required to perform the same tasks, allows me to reuse my assemblies, and keeps my options open to be able to move to other devices and platforms.

我想补充一点，即使有一个公认的答案——谁能说苹果不会拒绝那些有迹象表明是用Mono Touch构建的应用呢?

三个字:Linq to SQL

是的，很值。

在这篇文章中有很多开发者没有尝试过MonoTouch和Objective-C的传闻。似乎大多数Objective-C开发者从未尝试过MonoTouch。

我显然是有偏见的，但你可以看看MonoTouch社区一直在做什么:

http://xamarin.com

在那里，你会发现一些开发人员用Objective-C和c#开发的文章。

MonoTouch库的成本完全不是重点。你不应该在你的iPhone应用中使用Mono的原因是，它是一种拐杖。如果您懒得学习本机工具，那么我就没有理由相信您的产品值得下载。

编辑:4/14/2010用MonoTouch编写的应用程序不适合iTunes Store。这是应该的。苹果在Mac上看到了大量的浅端口，使用跨平台工具包，如Qt，或Adobe自己的System 7工具箱的部分重新实现，总之，它们不够好。
