• If the request timed out, you usually have to call the request again by yourself. AFNetworking+RetryPolicy handles that for you.

• AFNetworking+RetryPolicy category adds the ability to set the retry interval, retry count and progressive (uses power rule e.g. interval = 3 -> 3, 9, 27 etc.). failure is called no earlier then retryCount = 0, only fatalStatusCodes finishes the request earlier.

Allows

• How many times to try.
• Time interval between attempts in seconds.
• Progressive - next attempt will always take more time then the previous one if set.
• Set fatal status codes. These will trigger failure block immediately when received, ends all retry counts.

Installation

• Category uses AFNetworking 3.0 and above.

• For AFNetworking 1 support, use branch afn1-support. Will not be updated anymore.

• For AFNetworking 2 support, use branch afn2-support. Will not be updated anymore.

1. Add the AFNetworking+RetryPolicy category to your project as a regular library.
2. Use #import "AFNetworking+RetryPolicy.h"

Usage (Example)

• Simple GET request will look like this.

	AFHTTPSessionManager *manager = [AFHTTPSessionManager new];
    [manager GET:@"foo" parameters:nil progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        NSLog(@"%@", responseObject);
        
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"%@", error.localizedDescription);
        
    } retryCount:5 retryInterval:2.0 progressive:false fatalStatusCodes:@[@401, @403]];

• You can also turn on the logging in the category to see what happens (kDebugLoggingEnabled = true).
