Summary
In this chapter, we covered a lot of new things. You learned how to use the camera and how to integrate the camera roll when a camera is not available. We used our first UIScrollView in order to put in a row of images. We also added some interaction for our Scroll View so that we could apply filters to our image. This chapter had a lot of code, and there may be some parts that were confusing. Review these parts and make sure that you fully understand them. There are numerous things in this chapter that you can reuse in a number of other apps.
In the next chapter, we will wrap up the Create Reviews section.
