How to modify images

phdlove42 · 07-17-2011, 11:57 AM

Hey all,

I am attempting to make a kind of slider puzzle app and have found a few samples out there but I would like to learn how to make this not just paste some code. I have figured out how to select images from my own photos and get it to display to a UIImageView but that is where I am stuck. I understand that a way to do it would be using CGrect but that is confusing me as well.

specifically:
I would like to take an image, and slice it into at least 9 movable squares. Any help is appreciated even if its a link or a sample way to slice an image even once.

THANK YOU ALL.

You could use CGImageCreateWithImageInRect to get the nine separate pieces and create separate UIImages from it.

BRILLIANT. Kinda sad I missed that going through that earlier but that sounds great. When I use that does it actually create those images or are they references? My concern is that if I am trying to have them move when you try and solve the puzzle that they could lose whatever data is stored in them.

Valid concern?

Thanks again.

I'm not sure how you're planning to handle it. The most simple way would be to have 9 separate uiimageviews holding the 9 separate uiimages that you can create with that function.
