"Core Location - we've taken that and patched it into an API so you can create location-aware applications. The media layer... starting with Core Audio, this is the low-level audio layer; on top of that we've built OpenAL, an industry standard."
一些例子：“本地核心 - 我们得到它并且建立指向到API，所以你现在可以创建和地理位置相关的应用程序。Media （多媒体）层 - 和核心Audio一起启动，这是底层Audio（声音）层，更高的层我们建构了产业级标准的OpenAL?！?/P>
"Video playback: seamless video playback, uses our h.264 codec, built right in." So we can add new video codecs right? RIGHT? Sigh. "Core animation... OpenGL ES, the embedded version of OpenGL and a screamer for 3D graphics on the iPhone. In fact, this entire layer is heavily hardware accelerated."
“影片播放：采用我们内建的h.264 编码，实际无间断的影片播放?！?所以我们可以自已装codec编码进去是吗？是吗？唉...「核心动画...OpenGL标准的嵌入式版本OpenGL ES标准，以及iPhone 的3D图形的screamer（Bandage_man：个人估计原词应该是Streamer，即图形视频流。。。。）。事实这一整套层都经过高度的硬件加速才得以实现。”
10:29AM - "Cocoa Touch - our advanced touch event system; the accelerometer - what you might not know is that it's a full 3-axis sensor, and you can use that in your apps as well. ... this is the architecture for the iPhone OS, the most advanced mobile platform out there. We think we're years ahead of any other platform. We borrowed heavily from OS X -- we started on the shoulders of a giant."
10:29AM - “Cocoa Touch，我们最先进的触控事件系统，可以通过这个在你的软件中使用硬件中的加速感应器，三轴感应器等等，这就是iPhone 操作系统的架构，可以说是最先进的移动平台，我想我们还是不小心领先了其他系统平台不少年。通过OS X，我们学到了不少东西，可以说是站在巨人的肩膀上?！?/P>
"We have a comprehensive set of tools to help developers create and debug apps -- let's start with Xcode. We started there and enhanced it to support the iPhone; now we use Xcode to build the OS and apps for the iPhone. What is Xcode? It starts as a great source code editor -- it knows all about the iPhone SDK, will code-complete the APIs for the iPhone SDK."
“在Debug调试程序方面，我们也有相当多的工具，就先从Xcode的开始谈起吧！通过对于iPhone的的强化支持，我们可以使用Xcode来编写在iPhone上的程序甚至操作系统，什么是Xcode？它从一开始就是个强大的程序代码编辑工具，它了解iPhone SDK的全部，并且完成的iPhone的SDK的宣传短片?！?/P>
10:30AM - "... it also integrates directly with source control management system, subversion, cvs... integrates with iPhone SDK documentation, and also has a nice debugger -- it's also a great remote debugger. Plug an iPhone in, run the app live on your iPhone, and be debugging it from your Mac. This is incredibly powerful."
10:30AM - “...这个东西还直接整合了系统资源控制管理系统、Subversion系统、cvs系统...并和iPhone SDK文件整合在一起，并有良好调试Debug调试的能力，还有一个进行软件的Debug调试工具，一个最好的iPhone内建的用于远程Debug调试程序的插件。”在你的iPhone上运行它，用你的Mac通过连接iPhone来调试，它令人难以置信的强大。！”
10:32AM - "The next tool I'd like to talk about is Interface-Builder -- this is the tool you'll use to... wait for it... build your application interface. We have the complete library of iPhone interface assets, just drag them onto the canvas." Showing making connections from the view layers to control layers; it's also localizeable. "Next: Instruments..."
10:32AM - “我接下来谈及的工具是Interface Builder（界面构建器），也就是打造你的软件界面的主要方式。我们将提供完整的iPhone界面元件，只要把他们拖拽到屏幕上就好了。” 开始示范如何将界面上的控件和后台程序代码做关联。
