fail to set timeoutInterval when using subclass of AFHTTPRequestOperationManager

Question

I made a subclass of AFHTTPRequestOperationManager and wanted to set timeout to 3 seconds.

[netMgr.requestSerializer setTimeoutInterval:3.f];

But it doesn't work.

I can figure out that it's because the auto key value observing returns NO in automaticallyNotifiesObserversForKey when the key is timeoutInterval

Could anyone tell me the reason, or What's the right way to set timeout of request ?

Answer 1

I agree. Twenty-one days ago, the commit 0f3829f turned off automatic notification for these properties. It's the observer for these properties that ensures that any request serializer property changes translate to modification of the NSMutableURLRequest object for requests issued via AFHTTPRequestOperationManager .

I have to assume mattt had a reason for turning off this notification (looks like it is in response to issue #2523 , which should probably be reconsidered), so until this is remedied, I'd suggest one merely manually posting the notification.

[manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
manager.requestSerializer.timeoutInterval = ...;
[manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];

Note, this was fixed 26 March 2015 in commit 7d8e286 .
