Class: EyesPlatform: ImagesLanguage: Objective-C SDK:
Use this property to set and retrieve your Eyes license key.
To obtain your API key, see How to obtain your API key.
NSString* value; // give relevant initial value eyes.apiKey = value; value = eyes.apiKey
(copy, nonatomic) NSString *apiKey
Set this immediately after the Eyes object is created (before calling openWithApplicationName). If you have an environment variable called APPLITOOLS_API_KEY that is set to the value of your API key, then you do not need to call this method, and Eyes will take the string from the environment value.
