Read version from Info.plist

问题:

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

回答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"];

回答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)")
}

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
