Cancelling Parse retries on bad internet connection

I'm trying to do something quite simple : Stopping a parse.com query after a few seconds, with an NSTimer. I've read after some reasearch it's a good "trick" to use.

Here is how I create my timer : 

   NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:6.0
                                                          target:self
                                                        selector:@selector(stopRetries:)
                                                        userInfo:@{@"query":query}
                                                         repeats:NO];

Because i'm running this on a background thread (and outside a viewcontroller class), the timer is inside a dispatch_sync(dispatch_get_main_queue());

But whatever I do, I cannot stop the query, because [query cancel] doesn't do anything. I can't pass it in the userInfo of the timer. Breakpoints show it has an address and is "there" but it looks like junk inside.

What can I be doing wrong and what should I be doing instead?

My main goal is to make the parse.com query stop faster than 30 seconds, and warn the user with an alert.

You can Try this [self performSelector:@selector(abc) withObject:nil afterDelay:6.0];
or

You can Invalidate the timer
