MongoDB和Morphia - Traditionnal id（Long）而不是ObjectId(MongoDB and Morphia - Traditionnal id (Long) instead of ObjectId)

 您可以做的最好的事情是下载PhoneGap，将您的HTML5 / Sencha应用程序粘贴到新的PhoneGap应用程序的www目录中，使用XCode进行编译，以便您拥有一个为您的Sencha应用程序提供服务的本机PhoneGap应用程序。 然后，一旦你走得那么远，你可以创建一个加载外部应用程序的事件（例如，点击按钮等）。 
 
 PhoneGap提供了一个JavaScript入口点，您可以在Sencha开发中使用它。 您可以运行本机PhoneGap功能，包括PhoneGap的ChildBrowser插件（https://github.com/purplecabbage/phonegap-plugins/tree/master/iPhone/ChildBrowser）。 使用Sencha为PhoneGap的childbrowser插件调用JS入口点，并使用ChildBrowser加载外部应用程序。 
 
 你不能只做一个iframe的原因至少有三个： 
 
 
 
 有人抱怨说，在sencha应用程序中加载iframe已经破坏了Native中的应用程序。 （我想如果iframe包含一个复杂的网页，这可能会导致内存问题，这会导致应用程序崩溃。） 
 
 
 没有简单的方法来支持iframe中的滚动。 Sencha实现的基于JS的触摸滚动不会进入iframe。 （有可能让它与某种黑客一起工作，但你仍然有上面的问题＃1。） 
 
 
 您可能在iframe内部调整内容时遇到问题，因此看起来不错。 
 
 
 我应该注意，为了完整起见，有些人在本网站上表示他们已经能够通过JSONP / AJAX加载网页，然后将页面的HTML注入他们的Sencha应用程序。 我怀疑这可能是一致的，因为它可以简单地在PhoneGap上使用一些并使用ChildBrowser插件。 

The best thing you can do is download PhoneGap, stick your HTML5/Sencha app into the www directory of a new PhoneGap app, compile it with XCode so that you have a native PhoneGap app serving your Sencha app. Then, once you get that far, you can create an event for loading your external app (e.g., on a button click, etc.).
 
PhoneGap provides a JavaScript entry point that you can use within your Sencha development. You can run native PhoneGap functionality, including the ChildBrowser plugin for PhoneGap (https://github.com/purplecabbage/phonegap-plugins/tree/master/iPhone/ChildBrowser). Use Sencha to call the JS entry point for PhoneGap's childbrowser plugin, and use the ChildBrowser to load your external app.
 
The reasons you cannot just do an iframe are at least threefold:
 
 
 
Some have complained that loading an iframe inside of a sencha app has crashed the app in Native. (I imagine if the iframe contains a complex webpage, this may cause a memory issue, which would cause the app to crash.)
 
 
There is no easy way to support scrolling within the iframe. The JS-based touch scrolling that Sencha implements does not carry into the iframe. (It may be possible to get this to work with some kind of hack, but you'd still have problem #1 above.)
 
 
You may have issues sizing your content inside of the iframe so that it looks decent.
 
 
I should note, for the sake of completeness, that some have indicated on this site that they've been able to load a webpage via JSONP / AJAX and then inject the HTML of the page into their Sencha app. I suspect this may be as complicated to get working consistently as it would be to simply bone up a bit on PhoneGap and use the ChildBrowser plugin.
