Answer 1

I know a solution but its for fast iteration because final iterations can jump through value (looks not beautifully if there is a slow search), but the decision simple and short, can not the most beautiful from a architecture(but it can be corrected if it is necessary) realisation.

- (void)someAction 
{
    [self animateValue:0 toValue:1111 withStep:7 andIntervalSpeed:5];
}

-(void)animateValue:(int)value toValue:(int)toValue withStep:(int)step andIntervalSpeed:(int64_t)intervalSpeed
{
    self.currentValue = value; // @property (nonatomic) int currentValue;
    NSUInteger numberofIteration = (toValue - value)/step;

    int64_t interval = 0.0;
    for (NSUInteger i = 0; i < numberofIteration; i++) {

        dispatch_time_t start = DISPATCH_TIME_NOW;
        interval += intervalSpeed;

        dispatch_after(dispatch_time(start, interval * USEC_PER_SEC), dispatch_get_main_queue(), ^{

            if (((toValue - value)%step != 0) && (i == (numberofIteration-1)))
            {
                self.currentValue = toValue;
            }
            else
            {
                self.currentValue+= step;
            }

            NSLog(@"%d",self.currentValue);
            self.someLabel.text = [NSString stringWithFormat:@"%d",self.currentValue];

        });

    }
}
