如何向用户显示我的应用程序的当前项目版本？ [英] How to display the current project version of my App to the user?

问题描述

我想将目前版本加入我应用程式的「关于」部分。

I would like to add the current version into the "about" section of my app. As seen in this attached screenshot Apple offers versioning.

如何在应用程式中显示这些设定？

How do you display these settings in your app?

推荐答案

进一步搜索和测试后，我自己找到了解决方案。

After further searching and testing, I found the solution myself.

NSDictionary* infoDictionary = [[NSBundle mainBundle] infoDictionary];
NSLog(@"%i Keys:  %@", [infoDictionary count],
             [[infoDictionary allKeys] componentsJoinedByString: @" ,"]);

这个snipplet给了我以下输出：

This snipplet gave me the following output:

20个按键：NSBundleResolvedPath， CFBundleVersion ，NSBundleInitialPath，CFBundleIdentifier，NSMainNibFile，CFBundleIconFile，CFBundleInfoPlistURL，CFBundleExecutable，DTSDKName，UIStatusBarStyle，CFBundleDevelopmentRegion，DTPlatformName，CFBundleInfoDictionaryVersion，CFBundleSupportedPlatforms，CFBundleExecutablePath，CFBundleDisplayName ，LSRequiresIPhoneOS，CFBundlePackageType，CFBundleSignature，CFBundleName

20 Keys : NSBundleResolvedPath ,CFBundleVersion ,NSBundleInitialPath ,CFBundleIdentifier ,NSMainNibFile ,CFBundleIconFile ,CFBundleInfoPlistURL ,CFBundleExecutable ,DTSDKName ,UIStatusBarStyle ,CFBundleDevelopmentRegion ,DTPlatformName ,CFBundleInfoDictionaryVersion ,CFBundleSupportedPlatforms ,CFBundleExecutablePath ,CFBundleDisplayName ,LSRequiresIPhoneOS ,CFBundlePackageType ,CFBundleSignature ,CFBundleName

所以解决方案很简单：

NSString *version =[[[NSBundle mainBundle] infoDictionary] valueForKey:@"CFBundleVersion"];

但是，这是不当前项目版本但是plist文件的Bundle版本。

However, this is not the Current Project Version as seen in the screenshot but the Bundle Version of the plist file.
