In the custom picker, I am learning a bit on how to incorporate images into pickers. It is wild. Imagine, I can get pictures of things popped in to a spinning picker. Now I have an app in mind to build which does take pictures and cycles through them. However, there is a randomness component so if I want to go with many pictures, my guess is that I would use up a lot of application space. Now these little pngs are small, maybe up to 1K so it would take 1000 of these just to make a meg. I would assume meg-size apps are pulled down on the iPad or iPhone so I am not too concerned.
I got into UIImage and UIImageView. Not exactly why Apple has two controls The UIImage is for storage of the data and the UIImageView is for displaying what is stored. I guess I to go a little further to understand why both are needed. I guess maybe the stored one can be used in multiple controls or something - I don't know.
Well, anyways, I am a few pages away from finishing this long chapter (50 pages). This chapter is long but chapter 8 will be longer... 60 pages! So, I spent a lot of time on 7 and expect a lot more with 8. However, chapter 8 is about data tables and I love that stuff, so, hopefully chapter 7 will be done either tomorrow or Wednesday and then I can go for the big 8!
