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?
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)".
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.
Swift version for both separately:
Swift 3
let versionNumber = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
let buildNumber = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as! String
Swift 2
let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String
Its included in this repo, check it out:

This is what I did in my application
NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleVersion"];
Hopefully this simple answer will help somebody...
You can specify the CFBundleShortVersionString string in your plist.info and read that programmatically using the provided API.
There are two things - build version and app version.
To get App version:
NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleShortVersionString"];
To get Build version:
NSString *buildVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleVersion"];
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"];
// Syncs with App Store and Xcode Project Settings Input
NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleShortVersionString"];
You can try using dictionary as:-
NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];
NSString *buildVersion = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey]
Swift 5:
There are two things - App version and build version
To get App version:
if let appVersion = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String {
// present appVersion
}
To get Build version:
if let buildVersion = Bundle.main.infoDictionary?["CFBundleVersion"] as? String {
// present buildVersion
}
Thanks #Brad Larson♦ a lot
Read the info.plist file of your app and get the value for key CFBundleShortVersionString. Reading info.plist will give you an NSDictionary object
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() -> String {
let dictionary = Bundle.main.infoDictionary!
let version = dictionary["CFBundleShortVersionString"] as! String
let build = dictionary["CFBundleVersion"] as! String
return "v\(version).\(build)"
}
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!
func getAppVersion() -> String {
let dictionary = Bundle.main.infoDictionary!
let versionValue = dictionary["CFBundleShortVersionString"] ?? "0"
let buildValue = dictionary["CFBundleVersion"] ?? "0"
return "\(versionValue) (build \(buildValue))"
}
Based on #rajat chauhan answer without forced cast to String.
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.
You can try this method:
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleShortVersionString"];

I am using this code for in-app purchases, took it from RaywernderLich's tutorial.
// Encode the receiptData for the itms receipt verification POST request.
NSString *jsonObjectString = [self encodeBase64:(uint8_t *)transaction.transactionReceipt.bytes
length:transaction.transactionReceipt.length];
Now Xcode is saying
'transactionReceipt' is deprecated: first deprecated in iOS 7.0
How to fix it?
Regarding Deprecation
Since this question is technically asking how one should go about addressing the deprecated attribute its fair to assume that the OP is still deploying on an iOS version less than 7. Therefore you need to check for the availability of the newer API rather than calling it blindly:
Objective-C
Edit
As pointed out in the comments you can't use the respondsToSelector on NSBundle since that API was private in previous iOS versions
NSData *receiptData;
if (NSFoundationVersionNumber >= NSFoundationVersionNumber_iOS_7_0) {
receiptData = [NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]];
} else {
receiptData = transaction.transactionReceipt;
}
//now you can convert receiptData into string using whichever encoding:)
Swift
Since Swift can only be deployed on iOS 7 and above we can use the appStoreReceiptURL safely
if let receiptData = NSData(contentsOfURL: NSBundle.mainBundle().appStoreReceiptURL!) {
//we have a receipt
}
Regarding Receipt Validation
The newer API the receipt now contains the list of all transactions performed by the user. The documentation clearly outlines what a receipt looks like:
Meaning that if you really, really wanted to, you can iterate through all the items contained in the receipt to validate against each transaction.
For more on receipt validation you can read obc.io
Replace with something like:
[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]];
Convert NSData to NSString after that.....
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
if(!receipt) {
/* No local receipt -- handle the error. */
}
NSString *jsonObjectString = [receipt base64EncodedString];
I would like to know how can I access the iOS application target version.

Thanks
NSDictionary* infoDict = [[NSBundle mainBundle] infoDictionary];
NSString* versionNum = [infoDict objectForKey:#"CFBundleVersion"];
This will give the version number. Similarly you can get other attributes as well.
I want to read the bundle version info from Info.plist into my code, preferably as a string. How can I do this?
You can read your Info.plist as a dictionary with
[[NSBundle mainBundle] infoDictionary]
And you can easily get the version at the CFBundleVersion key that way.
Finally, you can get the version with
NSDictionary* infoDict = [[NSBundle mainBundle] infoDictionary];
NSString* version = [infoDict objectForKey:#"CFBundleVersion"];
for Swift users:
if let version = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") {
print("version is : \(version)")
}
for Swift3 users:
if let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") {
print("version is : \(version)")
}
I know that some time has passed since the quest and the answer.
Since iOS8 the accepted answer might not work.
This is the new way to do it now:
NSString *version = (__bridge id)CFBundleGetValueForInfoDictionaryKey(CFBundleGetMainBundle(), kCFBundleVersionKey);
Now in iOS 8 both fields are necessary. Earlier it works without the CFBundleShortVersionString. But now it is a required plist field to submit any app in app store. And kCFBundleVersionKey is compared for uploading every new build, which must be in incremental order. Specially for TestFlight builds. I do it this way,
NSString * version = nil;
version = [[NSBundle mainBundle] objectForInfoDictionaryKey:#"CFBundleShortVersionString"];
if (!version) {
version = [[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleVersionKey];
}
Swift 3:
let appBuildNumber = Bundle.main.infoDictionary!["CFBundleVersion"] as! String
let appVersion = Bundle.main.infoDictionary!["CFBundleShortVersionString"] as! String
Is there a way to read the app's bundled plist file, I am wanting to pull the value for Bundle version.
See Getting the Bundle’s Info.plist Data.
[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleVersionKey];
should get you the bundle version.
In Swift you can use:
let bundleVersion = Bundle.main.object(forInfoDictionaryKeykCFBundleVersionKey as String) as! String
or:
let bundleVersion = Bundle.main.infoDictionary?[kCFBundleVersionKey as String] as! String
If you want the short bundle versions string, you can use:
let shortBundleVersion = Bundle.main.object(forInfoDictionaryKey:"CFBundleShortVersionString") as! String
#define APP_VERSION [[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*)kCFBundleVersionKey]
I'm having some troubles with the bundle and somehow I can't save images from bundle to docs directory any more. Now I've got this error before building:
The document NSBundle.h could no be
saved
It apparently compiles well.
This is the kind of code I'm using:
//Get every name from plist array and append it to the full path
for( NSString *aName in namesPackage ) {
bundlePath = [[NSBundle mainBundle] pathForResource:aName ofType:#"png"];
if([fileManager fileExistsAtPath:bundlePath])NSLog(#"it exists in bundle: %#",bundlePath);
imagePath = [NSString stringWithFormat:#"%#/%#/%#",DOCUMENTS_FOLDER,package,aName];
[fileManager copyItemAtPath:bundlePath toPath:imagePath error:&anError];
if(anError) NSLog([anError description]);
}
Thanks for your help in advance.
You should use NSString's file extensions category:
-stringByAppendingPathComponent:
-stringByAppendingPathExtension:
That will take care of any potential issues with trailing slashes, etc.
Also, you should never pass any unknown string as the format argument to any variable length function, as they could contain format specifiers. Use NSLog(#"%#", anError) instead.
