#CSOperationsObserver

CSOperationsObserver is a little helper class that wraps KVO code for registering changes of the state of NSOperations.

##Example usage:

  • You get an NSOperation from your networking code. Your controller has a property operationsObserver

    id relatedData = [...]
  AFHTTPRequestOperation* operation = [...]
  [self.operationsObserver observeOperation:operation
  	 						  identifier:@"myJob"
  							    userInfo:@{@"relatedData":relatedData}];
[operation start];

  • In the same controller, you implement methods from the <CSOperationObserverProtocol>

    - (void)operationsObserver:(CSOperationsObserver*)observer
    didObserveCancellationOrFinishingOfOperationItem:(CSOperationObserverItem*)item
            withIdentifier:(NSString*)identifier
{
    //Do whatever you want
    if ([identifier isEqualToString:@"myJob"]) {
  	  id relatedData = item.userInfo[@"relatedData"];
  	  [...]
    }
}
