版本号问题

iOS的版本号，一个叫做Version，一个叫做Build，这两个值都可以在Xcode 中选中target，点击“Summary”后看到。 Version在plist文件中的key是“CFBundleShortVersionString”，和AppStore上的版本号保持一致，Build在plist中的key是“CFBundleVersion”，代表build的版本号，该值每次build之后都应该增加1。这两个值都可以在程序中通过下面的代码获得：

[[[NSBundle mainBundle] infoDictionary] valueForKey:@"key"]

［2］具体实现

代码实现获得应用的Verison号：
