In Photobombers, sometimes you're adding @properties to the .m file, and sometimes to the .h file. Why is that?

For example, all the @property declarations are in the header file for THPhotoCell, but all are in the implementation file for THPhotosViewController. Should they not always be in the .h file?

Yes, in *.h -> public in *.m -> private

What I think is the reasoning here is that public @properties are added to the .h file, making those properties accessible from outside the class, and private @properties are added in the .m file making them only accessible from within the class itself.

Is that correct?
