This application is an example of how to use the Instagram API for authentication.
InstagramService is the class that handles the authentication, implements the following functions:
func startAuthorization(withURL url: NSURL)
func requestAccessToken(withCode code: String)
func logout()
Implementation of InstagramDelegate is needed to get callback from the first two functions, posible callbacks are:
func didGetAuthorizationCode(code: String)
func didFailAuthorizing()
func didGetAccessToken(token: String, forUser user: User)
func didFailGettingAccessToken()
Some of the concepts applied to build this example are:
- Generics
- Protocols
- MVVM
