UISwipeGestureRecognizer swipe left and finger up

Question

I am using a UISwipeGestureRecogizer to swipe left and right by using UISwipeGestureRecognizerDirectionRight and UISwipeGestureRecognizerDirectionLeft and its working totally fine but the default swipe is too sensitive, its just a little bit more than a tap.

Is there any way by which I can make it work like when a scrollView works when its paging enable property is true that till the user doesnt lifts its finger up, its doesnt work.
It will be fine if the view doesn't move with the finger moving, and only work when a left or right gesture is performed and the finger is lifted. Thanks.

A UISwipeGestureRecognizer will not give you any option to change the sensitivity or any other aspect of the swipe. To obtain more control over the swipe, you could use one among the following:

UIPanGestureRecognizer

Here is something to try with UIPanGestureRecognizer:

- (void)handleGesture:(UIPanGestureRecognizer *)gestureRecognizer{
    CGPoint velocity = [gestureRecognizer velocityInView:yourView];
    if(velocity.x > 0){
        //Right gesture
    }else{
        //Left gesture
    }
}

UIResponder

All UIViews inherit from UIResponder, so you can use the touchesBegan, touchesMoved and touchesEnded method for calculating the touch. Try something like this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
    UITouch *touch = [touches anyObject];
    start = [touch locationInView:self.view];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch *touch = [touches anyObject];
    CGPoint end = [touch locationInView:self.view];   
    //Compare start and end points here.
}
