How does this lib handle oauth session key and refresh key

[ghost]

hi, am new to objective-c and i want to use this library to get random image from r/dachshunds gallery. I know that oauth for imgur requires a session key and a refresh key to access make a call to their API. Will this library give me session key and refresh key? does this library handle expiration of session key (and get new session key) for me?

Sorry if my questions sound naive, I dont have a clear view since I haven't used the library but thought i'd ask to know better. Thanks!
