Read version from Info.plist

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"];
