Question

Im using pan gesture for showing different images.

Pan gesuture is detecting correctly.

The problem is i want to get the time-interval between a pan gesture (in milliseconds).

So how can i fetch the time interval between a pan gesture in iPhone.

i tried in this way but it is not showing correctly.

else if([sender state] ==UIGestureRecognizerStateChanged ) 
    {
        NSLog(@"pan velocity %@ ",[NSDate date]);

        self.previousTime = [NSDate date];
        NSDate *currentTime = [NSDate date];
        NSTimeInterval timeDifference =  [currentTime timeIntervalSinceDate:previousTime];
        //self.previousTime = currentTime;
        NSLog(@"%f sssss",timeDifference);
    }

Can anyone please help me how to find the time interval between a pan gesture in iOS.

Thanks in advance.

Answer 1

NSDate *previousTime = [NSDate date];
double timeDifference = [previousTime timeIntervalSinceNow] * -1000.0;
