我的iphone应用程序如何检测自己的版本号？ [英] How can my iphone app detect its own version number?

问题描述

我正在写一个iPhone应用程序。它已经发布了，但我想添加一个显示其版本号的功能。

I'm writing an iPhone app. It's already been published, but I would like to add a feature where its version number is displayed.

我不想手动对我发布的每个版本执行此操作...

I'd rather not have to do this manually with each version I release...

在Objective-C中是否有办法找出我的应用程序的版本？

Is there a way in objective-C to find out what the version is of my app?

推荐答案

正如我在此描述的那样，我使用脚本用我当前的Subversion版本号重写头文件。该修订号存储在kRevisionNumber常量中。然后，我可以使用类似于以下内容的方式访问版本和修订号：

As I describe here, I use a script to rewrite a header file with my current Subversion revision number. That revision number is stored in the kRevisionNumber constant. I can then access the version and revision number using something similar to the following:

[NSString stringWithFormat:@"Version %@ (%@)", [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"], kRevisionNumber]

将创建格式为Version 1.0（51）的字符串。

which will create a string of the format "Version 1.0 (51)".
