推荐答案

我当时在WWDC上，我可以告诉您，如果您真的想开发iPhone，请购买这些视频.它们充满了实用信息，尤其是有关iPhone 3GS(以及现在的新iPod touch)上新增的iPhone OS 3.0和OpenGL ES 2.0方面的信息.演示者比您通常在技术会议上看到的要精巧得多.

I was at WWDC, and I can tell you that if you are serious about developing for the iPhone, buy these videos. They are full of practical information, particularly in regards to the new iPhone OS 3.0 additions and OpenGL ES 2.0 on the iPhone 3GS (and now, new iPod touch). The presenters are much more polished than you usually see at technical conferences.

例如，我想在我的应用程序中实现自定义复制和粘贴支持，所以我观看了视频，一个半小时后，我一切正常.我是花时间在网上还是在文档中查找正确的信息，这比WWDC会话的简单这就是您需要知道的"方法花费的时间要长得多.

For example, I wanted to implement custom copy-and-paste support in my application, so I watched the video and an hour and a half later I had everything working. Were I to take the time to track down the right information online or in documentation, it would have taken me much longer than the simple "this is what you need to know" approach of the WWDC session.

视频经过很好的编码，可以在iPhone(或iPod)上播放，因此您可以随身携带它们在飞机上或坐在室外观看.

The videos are nicely encoded to play on your iPhone (or iPod), so you can take them with you to watch on an airplane or while sitting outside.

如果我没记错的话，您还可以访问一些示例代码，这些示例代码仅提供给WWDC与会者，并且尚未(尚未)发布在网上.总体而言，您会从中获得很多收益.

If I'm not mistaken, you also get access to some sample code that was only made available to WWDC attendees and hasn't (yet) been posted online. Overall, you get a lot of content for your money.
