How to access app info.plist variables in code

Info.plist  [information property list file]:  is a structured text file that contains essential configuration information for a bundled executable

Attributes from the info.plist for your project are directly accessible by the following...

[[NSBundle mainBundle] objectForInfoDictionaryKey:key_name];


Example:  NSString *appVersion = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];


An information property list file is a structured text file that contains essential configuration information for a bundled executable. The file itself is typically encoded using the Unicode UTF-8 encoding and the contents are structured using XML. The root XML node is a dictionary, whose contents are a set of keys and values describing different aspects of the bundle. The system uses these keys and values to obtain information about your app and how it is configured. As a result, all bundled executables (plug-ins, frameworks, and apps) are expected to have an information property list file.

By convention, the name of an information property list file is Info.plist. This name of this file is case sensitive and must have an initial capital letter I. In iOS apps, this file resides in the top-level of the bundle directory. In OS X bundles, this file resides in the bundle’s Contents directory. Xcode typically creates this file for you automatically when you create a project of an appropriate type.
