NSTimer not working while dragging a UITableView

I have an application with a countdown timer. I've made it with a label that is updated with a function called from a timer this way:

...
int timeCount = 300; // Time in seconds
...
NSTimer *myTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(actualizarTiempo:) userInfo:nil repeats:YES];
...
- (void)actualizaTiempo:(NSTimer *)timer {
    timeCount -= 1;
    if (timeCount <= 0) {
        [timer invalidate];
    } else {
        [labelTime setText:[self formatTime:timeCount]];
    }
}

Note: formatTime is a function which receive an integer (number of seconds) and returns a NSString with format mm:ss

Everything works ok, that is, the time counts down but the problem is that I have a UITableView in the application and if I touch the table and drag it (to move along the cells) the timer stops until I release my finger from the screen...

Is this behavior normal? If it is, is there any way to avoid it and make the timer work while dragging the table?

Swift version 4+:

var timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(self.TimerController), userInfo: nil, repeats: true)
RunLoop.main.add(timer, forMode: RunLoopMode.commonModes)

if you want to repeat for example as a counter then set repeat = true else = false
