Show HN: Over 100 tested iOS code samples

Interesting concept, here are some issues in my opinion:

1) No price shown on the first page, I have to click on Buy to see that it is $99 CAD

2) No mention of the source of the code, where it is coming from, what makes it tested, who tested it.

3) What about the license. Do you own it and are you granting it, is it open source code that you have scoured, what are the individual pieces of licenses and will I have to worry about that too.

4) What code samples are there? The image doesn't tell me much, need a list of code samples, including the sample of code so that I can figure out the quality before shelling out $99 CAD.

The picture shown on the homepage is kinda scrunched, http://i.imgur.com/oHK40.png.

I'm very weary about this conceptually. If you don't know what a piece of code is doing, then you shouldn't be putting it into your project; because when it breaks, you wont know how to fix it. So a cookbook with explanations would accompany this nicely.

Licence concerns me, the page states (We've searched so you don't have to) are you certain you are legally allowed to publish these code samples? Creating your own is fine, but if you've searched places like blogs, stack overflow, etc, you could be infringing copyright. I'll release code samples for free use, but you aren't allowed to re-publish them or make a profit off of them.
