I Am using iCarousel framework.

There I want to find out the swipe direction of a view, because i am having next and previous actions, need to give for right and left scrolling.

If I understand your question correctly, you want to know when the user scrolled the carousel and to know in which direction did she scroll. If so, you should implement the method
- (void)carouselCurrentItemIndexDidChange:(iCarousel *)carousel;
and compare the new index with the previous (stored) value - if the new one is greater than before, the user scrolled right, if it's smaller - scroll left.
