Read version from Info.plist - iphone

Question

I want to read the bundle version info from Info.plist into my code, preferably as a string. How can I do this?

Answer 1

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"];

Answer 2

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)")
}

Answer 3

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);

Answer 4

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
