App上架版本号配置的注意事项：CFBundleVersion与CFBundleShortVersionString设置，以及内部检查版本更新的代码

一、CFBundleVersion与CFBundleShortVersionString设置

CFBundleVersion：标识内部版本号，如果发包错误时可以将错误的撤回及时更改内部版本号即可。

CFBundleShortVersionString:代表应用的发布版本号，该版本的版本号是三个时期分隔的整数组成的字符串。第一个整数代表重大修改的版本，如实现新的功能或重大变化的修订。第二个整数表示的修订，实现较突出的特点。第三个整数代表维护版本。

如上图：Version对应的就是CFBundleShortVersionString 发布版本号 如当前上架版本为1.0.0  之后你更新的时候可以改为1.0.1）

           Build 对应的就是CFBundleVersion  （内部版本号，用以记录开发版本的，每次更新的时候都需要比上一次高 如：当前版本是1.0.1.1 ,下次可以改为：1.0.1.2）

 二、内部检查版本更新

由以上配置信息可知，要检查版本更新需对比当前的版本和请求返回的版本号，如果不一样才更新，如果一样则不更新；代码如下：

 

请求以上代码中的url网址时，jsonDic字典中的数据如下：

    resultCount = 1;

    results =     (

                {

                "Infrequent/Mild Alcohol, Tobacco, or Drug Use or References",

                "Infrequent/Mild Mature/Suggestive Themes"

            );

最后强调一点切记：当从网络接口获取的版本号和本地的版本号对照的时候一定要使用：CFBundleShortVersionString，不然会造成错误的。。
