Rhomobile Rhodes (http://rhomobile.com/products/rhodes)在方法上与PhoneGap非常相似，但它是唯一具有以下功能的框架:

模型-视图-控制器模式(如 大多数web框架提供) 对象关系管理器 支持所有流行的智能手机(包括Windows Phone 7) 托管开发服务(不仅仅是托管构建):http://rhohub.com RhoStudio IDE中的完整调试器和无sdk模拟器 支持同步脱机数据

我在stackoverflow上注册只是为了评论上面投票最多的答案。糟糕的是，stackoverflow不允许新成员发表评论。所以我必须让这个评论看起来更像一个答案。

Rory Blyth的回答包含了关于这两个javascript移动框架的一些有效观点。然而，他的关键点是不正确的。事实是，Titanium和PhoneGap大同小异。它们都通过一组javascript api公开手机功能，应用程序的逻辑(html, css, javascript)在原生WebView控件中运行。

PhoneGap is not just a native wrapper of a web app. Through the PhoneGap javascript APIs, the "web app" has access to the mobile phone functions such as Geolocation, Accelerometer Camera, Contacts, Database, File system, etc. Basically any function that the mobile phone SDK provides can be "bridged" to the javascript world. On the other hand, a normal web app that runs on the mobile web browser does not have access to most of these functions (security being the primary reason). Therefore, a PhoneGap app is more of a mobile app than a web app. You can certainly use PhoneGap to wrap a web app that does not use any PhoneGap APIs at all, but that is not what PhoneGap was created for. Titanium does NOT compile your html, css or javascript code into "native bits". They are packaged as resources to the executable bundle, much like an embedded image file. When the application runs, these resources are loaded into a UIWebView control and run there (as javascript, not native bits, of course). There is no such thing as a javascript-to-native-code (or to-objective-c) compiler. This is done the same way in PhoneGap as well. From architectural standpoint, these two frameworks are very similar.

Now, are they any different? Yes. First, Titanium appears to be more feature rich than PhoneGap by bridging more mobile phone functions to javascript. Most noticeably, PhoneGap does not expose many (if any) native UI components to javascript. Titanium, on the other hand, has a comprehensive UI APIs that can be called in javascript to create and control all kinds of native UI controls. Utilizaing these UI APIs, a Titanium app can look more "native" than a PhoneGap app. Second, PhoneGap supports more mobile phone platforms than Titanium does. PhoneGap APIs are more generic and can be used on different platforms such as iPhone, Android, Blackberry, Symbian, etc. Titanium is primarily targeting iPhone and Android at least for now. Some of its APIs are platform specific (like the iPhone UI APIs). The use of these APIs will reduce the cross-platform capability of your application.

所以，如果你想让你的应用看起来更“原生”，Titanium是一个更好的选择。如果你想更容易地将你的应用“移植”到另一个平台，PhoneGap会更好。

更新12/04/2010: 我决定给这篇文章一个年度审查，以保持其信息的最新。许多事情在一年中发生了变化，使得最初的帖子中的一些信息过时了。

最大的变化来自钛金属。今年早些时候，Appcelerator发布了Titanium 1.0，从架构的角度来看，它与之前的版本有很大的不同。在1.0中，UIWebView控件不再使用。相反，您可以为任何UI函数调用Titanium api。这一变化意味着以下几点:

Your app UI becomes completely native. There is no more web UI in your app since the native Titanium APIs take over control of all your UI needs. Titanium deserves a lot of credit by pioneering on the "Cross-Platform Native UI" frontier. It gives programmers who prefer the look and feel of native UI but dislike the official programming language an alternative. You won't be able to use HTML or CSS in your app, as the web view is gone. (Note: you can still create web view in Titanium. But there are few Titanium features that you can take advantage of in the web view.)Titanium Q&A: What happened to HTML & CSS? You won't be able to use popular JS libraries such as JQuery that assume the existence of an DOM object. You continue to use JavaScript as your coding language. But that is pretty much the only web technology you can utilize if you come to Titanium 1.0 as a web programmer.

钛视频:钛1.0有什么新功能。

现在，Titanium 1.0会把你的JavaScript编译成“原生位”吗?不。Appcelerator终于在这个开发者博客上澄清了这个问题:Titanium Guides Project: JS Environment。我们程序员比市场部的人更真诚，不是吗?:-）

接下来是PhoneGap。关于PhoneGap没有太多新东西可说。我的看法是，PhoneGap的开发在IBM今年晚些时候加入之前并不活跃。有些人甚至认为IBM为PhoneGap贡献的代码比Nitobi还多。不管这是不是真的，PhoneGap正在积极开发中，这是很好的。

PhoneGap继续以网页技术为基础，即HTML, CSS和JavaScript。PhoneGap似乎不打算像Titanium那样将原生UI功能与JavaScript连接起来。虽然Web UI在性能和原生外观上仍落后于原生UI，但这种差距正在迅速缩小。在web技术中，有两个趋势可以确保移动web UI在性能方面的亮点:

JavaScript引擎从解释器转移到虚拟机。JavaScript是JIT编译成本地代码，以便更快地执行。Safari JS引擎:SquirrelFish Extreme 网页渲染从依赖CPU转向使用GPU加速。在硬件加速的帮助下，页面转换和3D动画等图形密集型任务变得更加流畅。GPU加速合成Chrome

Such improvements that are originated from desktop browsers are being delivered to mobile browsers quickly. In fact, since iOS 3.2 and Android 2.0, the mobile web view control has become much more performing and HTML5 friendly. The future of mobile web is so promising that it has attracted a big kid to town: JQuery has recently announced its mobile web framework. With JQuery Mobile providing UI gadgets, and PhoneGap providing phone features, they two combined creates a perfect mobile web platform in my opinion.

我还应该提到Sencha Touch作为另一个移动web UI小工具框架。Sencha Touch 1.0版本最近发布，采用了包括GPLv3在内的双重授权模式。Sencha Touch可以很好地与PhoneGap合作，就像JQuery Mobile一样。

如果你是一个GWT程序员(像我一样)，你可能想看看GWT Mobile，这是一个使用GWT创建移动web应用程序的开源项目。它包括一个PhoneGap GWT包装器，允许在GWT中使用PhoneGap。

你应该学习objective - c和编程原生应用程序。不要依赖这些你以为会让生活更容易的东西。苹果确保最简单的方法就是使用他们的本地工具和语言。对于你的100行javascript，我可以在3行代码中做同样的事情，或者完全不需要代码，这取决于元素。看一些教程——如果你理解javascript，那么objective - c并不难。变通办法很糟糕，苹果可以随时把你的插头拔掉。

在你提到的解决方案中，似乎没有一个能让你直接访问OS 3.0中引入的MapKit框架。

由于谷歌Maps HTML小部件远不如MapKit(参见谷歌Latitude的例子)，您可能最好开发一个原生Cocoa触摸应用程序，或者选择一个可以扩展以添加MapKit集成的解决方案。PhoneGap以这种方式是可扩展的(它是开源的，所以默认是)，其他一些解决方案可能也是如此。
