Table views, I.e.the scrolling asection title action in the pluralsight ipad app, where you scroll and the title remains for the section

Ben Scheirman said:

This is simply done by grouping your data into sections, typically in an NSDictionary. Then you create an NSArray of sections and return a title for each section in `tableView:titleForHeaderInSection:` method.

This creates the effect you want. If you want to customize how it looks, implement the `tableView:viewForHeaderInSection` and return your own custom view.

CoconutKit ViewControllerContainer

2013-02-04T12:40:50-08:00

Alex Kestner suggested:
Ran across the CoconutKit library (https://github.com/defagos/CoconutKit) recently doing some research for an iOS project I'm working on and thought it provided a number of seriously useful features. I'm particularly interested in the View Controller Container classes, which the CoconutKit dev writes about (at great length) here: subjective-objective-c.blogspot.com/2011/08/writing-high-quality-view-controller.html. Although it's a large library and I'm sure there's much more to be explored.

Provide an annual subscription option [is now completed]

2012-12-01T06:08:47-08:00

I think $9/mo is fair for content posted weekly... but I'm trying to minimize the slew of monthly subscription fees for various web-based products and services. The services themselves are worthwhile, but I'd prefer an option to pay annually and then forget about it for 11-ish months. Then I can decide whether to renew. Even if you make it a "pay annually, get a free month" option at $99 - you'd still make more than currently (over the course of a year) than with the "1/2 off for 3 months", which is going to be a few dollars less. I would think it'd be helpful for you also because there'd be some predictability for those months that someone has pre-paid.

App Authentication with AFNetworking [is now completed]

2012-11-08T07:36:48-08:00

There are a lot of tutorials available on AFNetworking, however I haven't been able to find one that shows how to authenticate users. I think that such an important element of an app would have more attention but it seems that is not the case. So I would def pay for a tutorial on best practices for how to do this with a Rails backend if possible please ;)
