PhoneGap生成错误

Question

我是PhoneGap新手，当我使用OSX10.6.2和Xcode3.1.3编译捆绑的PhoneGap.xcodeproject时，我遇到了这些错误

我错过了什么？

非常感谢唐

您是否安装了最新的iPhone开发工具包？如果您使用的是Xcode3.1，我不相信您会这样做；3.2和更高版本是当前版本。

Location.m:33: warning: 'CLLocationManager' may not respond to '-headingAvailable'

具体地说，这表明CLLocationManager的声明没有-headingAvailable方法。该方法是在iPhone OS 3.0中添加的。因此，我敢打赌您已经安装了2.x系列的开发工具包？
