Based on others' answers and @mattt's suggestion on related project issues, here is a drop-in quickie if you are subclassing <code>AFHTTPClient</code>:

<pre><code>@implementation SomeAPIClient // subclass of AFHTTPClient

// ...

- (NSMutableURLRequest *)requestWithMethod:(NSString *)method path:(NSString *)path parameters:(NSDictionary *)parameters {
 NSMutableURLRequest *request = [super requestWithMethod:method path:path parameters:parameters];
 [request setTimeoutInterval:120];
 return request;
}

- (NSMutableURLRequest *)multipartFormRequestWithMethod:(NSString *)method path:(NSString *)path parameters:(NSDictionary *)parameters constructingBodyWithBlock:(void (^)(id &lt;AFMultipartFormData&gt; formData))block {
 NSMutableURLRequest *request = [super requestWithMethod:method path:path parameters:parameters];
 [request setTimeoutInterval:120];
 return request;
}

@end
</code></pre>

Tested to work on iOS 6.

Can't we do this with a timer like this:

In .h file

<pre><code>{
NSInteger time;
AFJSONRequestOperation *operation;
}
</code></pre>

In .m file

<pre><code>-(void)AFNetworkingmethod{

 time = 0;

 NSTtimer *timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(startTimer:) userInfo:nil repeats:YES];
 [timer fire];


 operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
 [self operationDidFinishLoading:JSON];
 } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
 [self operationDidFailWithError:error];
 }];
 [operation setJSONReadingOptions:NSJSONReadingMutableContainers];
 [operation start];
}

-(void)startTimer:(NSTimer *)someTimer{
 if (time == 15&amp;&amp;![operation isFinished]) {
 time = 0;
 [operation invalidate];
 [operation cancel];
 NSLog(@"Timeout");
 return;
 }
 ++time;
}
</code></pre>

You can set the timeout interval through requestSerializer setTimeoutInterval method.You can get the requestSerializer from an AFHTTPRequestOperationManager instance.

For example to do a post request with a timeout of 25 second :

<pre><code> NSDictionary *params = @{@"par1": @"value1",
 @"par2": @"value2"};

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

 [manager.requestSerializer setTimeoutInterval:25]; //Time out after 25 seconds

 [manager POST:@"URL" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

 //Success call back bock
 NSLog(@"Request completed with response: %@", responseObject);


 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
 //Failure callback block. This block may be called due to time out or any other failure reason
 }];
</code></pre>

My project is using AFNetworking.
