I think you are looking for a circular scroll view. You can find lots of samples in net. Here are a few

The logic should be something like this If you have reached the end of the scrollview(which you can check using the content offset) you should set the content offset to that of the first image mostly 0. If you are at first image then set the content offset of the scrollview as the content offset of the last image
