How can my iphone app detect its own version number

Question

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   I d rather not have to do this manually with each version I release      Is there a way in objective-C to find out what the version is of my app

You can try this method   NSString  version      NSBundle mainBundle  infoDictionary  objectForKey   CFBundleShortVersionString

Read the info plist file of your app and get the value for key CFBundleShortVersionString  Reading info plist will give you an NSDictionary object

User · Answer

You can use the infoDictionary which gets the version details from info plist of you app  This code works for swift 3  Just call this method and display the version in any preferred UI element   Swift-3    func getVersion   - gt  String       let dictionary   Bundle main infoDictionary      let version   dictionary  CFBundleShortVersionString   as  String     let build   dictionary  CFBundleVersion   as  String     return  v  version    build

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    which will create a string of the format  Version 1 0  51

This is a good thing to handle with a revision control system  That way when you get a bug report from a user  you can check out that revision of code and  hopefully  reproduce the bug running the exact same code as the user    The idea is that every time you do a build  you will run a script that gets the current revision number of your code and updates a file within your project  usually with some form of token replacement   You can then write an error handling routine that always includes the revision number in the error output  or you can display it on an  About  page

Building on Brad Larson s answer  if you have major and minor version info stored in the info plist  as I did on a particular project   this worked well for me   -  NSString   appNameAndVersionNumberDisplayString       NSDictionary  infoDictionary     NSBundle mainBundle  infoDictionary       NSString  appDisplayName    infoDictionary objectForKey   CFBundleDisplayName        NSString  majorVersion    infoDictionary objectForKey   CFBundleShortVersionString        NSString  minorVersion    infoDictionary objectForKey   CFBundleVersion         return  NSString stringWithFormat       Version                            appDisplayName  majorVersion  minorVersion       Now revving a minor version manually can be a pain  and so using a source repository revision number trick is ideal  If you ve not tied that in  as I hadn t   the above snippet can be useful  It also pulls out the app s display name

A succinct way to obtain a version string in X Y Z format is    NSBundle mainBundle  infoDictionary   CFBundleVersion     Or  for just X Y    NSBundle mainBundle  infoDictionary   CFBundleShortVersionString     Both of these snippets returns strings that you would assign to your label object s text property  e g   myLabel text    NSBundle mainBundle  infoDictionary   CFBundleVersion

If you need a combination of both version and build num  here s a short way using Swift 3   let appVersion   Bundle main infoDictionary   CFBundleShortVersionString    let buildNum   Bundle main infoDictionary   CFBundleVersion    let versionInfo      appVersion   build   buildNum       versionInfo is now something like  2 3 0  build 17     Add an as  String to the end of either the appVersion or buildNum line to get only that portion as a String object  No need for that though if you re looking for the full versionInfo   I hope this helps
