iOS从info.plist 获取项目的名称及版本号

NSString *executableFile = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleExecutableKey];

    NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];

 

还有其它很多信息可由infoDictionary获得,以下是官方文档里的说明：

information Property List Keys
Standard keys found in a bundle’s information property list file.

const CFStringRef kCFBundleInfoDictionaryVersionKey;
const CFStringRef kCFBundleExecutableKey;
const CFStringRef kCFBundleIdentifierKey;
const CFStringRef kCFBundleVersionKey;
const CFStringRef kCFBundleDevelopmentRegionKey;
const CFStringRef kCFBundleNameKey;
const CFStringRef kCFBundleLocalizationsKey;

Constants
kCFBundleInfoDictionaryVersionKey
The version of the information property list format.
Available in iOS 2.0 and later.
Declared in CFBundle.h.
kCFBundleExecutableKey
The name of the executable in this bundle (if any).
Available in iOS 2.0 and later.
Declared in CFBundle.h.
kCFBundleIdentifierKey
The bundle identifier.
Available in iOS 2.0 and later.
Declared in CFBundle.h.
kCFBundleVersionKey
The version number of the bundle.
For Mac OS 9 style version numbers (for example “2.5.3d5”), clients can use CFBundleGetVersionNumber instead of accessing this key directly since that function will properly convert the version string into its compact integer representation.
Available in iOS 2.0 and later.
Declared in CFBundle.h.
kCFBundleDevelopmentRegionKey
The name of the development language of the bundle.
When CFBundle looks for resources, the fallback is to look in the lproj whose name is given by the kCFBundleDevelopmentRegionKey in the Info.plist file. You must, therefore, ensure that a bundle contains an lproj with that exact name containing a copy of every localized resource, otherwise CFBundle cannot guarantee the fallback mechanism will work.
Available in iOS 2.0 and later.
Declared in CFBundle.h.
kCFBundleNameKey
The human-readable name of the bundle.
This key is often found in the InfoPlist.strings since it is usually localized.
Available in iOS 2.0 and later.
Declared in CFBundle.h.
kCFBundleLocalizationsKey
Allows an unbundled application that handles localization itself to specify which localizations it has available.
Available in iOS 2.0 and later.
Declared in CFBundle.h.
Declared In
