Hi,
I am using carousel in one of my project. I am facing that carousel not smoothly scroll. When you scroll or drag items it take a jump or say kind of stop in half way and then complete the scroll. I want that it scroll complete item smoothly. Scroll items smoothly with no jerk or jump.In my project, [self.carousel addSubview:UITextView]

Please suggest how can i improve this.
