objective c - Refer to build number or version number in code

Question

It's easy to set the build and version numbers manually in Xcode, and I learned how to increment them with a macro at build time. But how do I reference their values in code?

Answer 1

NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
NSString *appVersion = [infoDict objectForKey:@"CFBundleShortVersionString"]; // example: 1.0.0
NSString *buildNumber = [infoDict objectForKey:@"CFBundleVersion"]; // example: 42
