I have an approach for stopping or deactivate the timer, Before apply this make sure that you tried all the cases as mentioned above so you can also understand that why this approach used at last.

 // Instead of self use NSTimer class, it will not provide you any crash and in selector placed any empty function and setRepeats to NO

self.messageTimer = [NSTimer scheduledTimerWithTimeInterval:100.0
                       target:NSTimer selector:@selector(emptyFunctionCalling)
                                                                   userInfo:nil
                                                                    repeats:NO];
[self.messageTimer invalidate];
 self.messageTimer = nil;

So whenever the case occured that timer will not stopping then entering in this code the timer will stops permanently.
