I'm currently building a collection view with a header, I've got all the pieces working, so I don't necessarily have a question/problem about code, header works fine and so do the cells. My question is about the header and when you drag it down, you can see the background color. Currently, I have my header's color set to Gray, and the background color of the controller is set to white, so when I drag the header down, I can see the white background.
My question is.. what code do I need to implement in order for the gray header to be continuously stuck to the top even as I drag the header down?
I'd like to figure how to implement this because I want to keep the spacing of my collection view cells white and not gray (If I were to change the background color to gray).
