AFNetworking+RetryPolicy

If a request timed out, you usually have to call that request again by yourself. AFNetworking+RetryPolicy is an objective-c category that adds the ability to set the retry logic for requests made with AFNetworking.

Features:

•  retryCount – How many times to try.
•  retryInterval – Time interval between attempts in seconds.
•  progressive – Next attempt will always take more time than the previous one. (Uses Exponentiation)
•  fatalStatusCodes – These will trigger failure block immediately when received and ends current retry.
