How to declare enum in Objective-C

Apple recommends defining enums like this since Xcode 4.4:

typedef enum ShareType : NSUInteger {
    kTwitter,
    kFacebook,
    kGooglePlus
}

They also provide a handy macro NS_ENUM:

typedef NS_ENUM(NSUInteger, ShareType) {
    kTwitter,
    kFacebook,
    kGooglePlus
};

These definitions provide stronger type checking and better code completion.
