我是PhoneGap的新手，在编译捆绑的PhoneGap.xcodeproject时遇到了这些错误 我使用的是osx 10.6.2和xcode 3.1.3
我错过了什么？
非常感谢 唐

答案 0 :(得分：0)
您是否安装了最新的iPhone开发套件？如果您使用的是Xcode 3.1，我不相信您会这样做; 3.2及以上是目前的版本。
Location.m:33: warning: 'CLLocationManager' may not respond to '-headingAvailable'
具体而言，这表明CLLocationManager的声明没有-headingAvailable方法。该方法已添加到iPhone OS 3.0中。因此，我敢打赌你安装了2.x系列的开发套件？
