RubyMotion Tip of the Week
When you’re creating a UITableView or UITableViewController you can use many different cell types in one table. A logical “unit” doesn’t have to be only one cell.
For example: imagine you have a list of comments, and some of the comments have images. Rather than making only one comment cell class, make a CommentImageCell and a CommentTextCell. This is much easier than dynamically changing the height of the cell depending on wether it has an image or not. It’s also more efficient.
I like to create an array of rows, with their class and their data. Then when creating that cell in the delegate you know which kind of cell to create and you can apply the data.
rows = [
{ klass: CommentTextCell, data: comment.body },
{ klass: SomeOtherCell, data: some_data }
]
RubyMotion App of the Week
This is strange, but I’m intrigued. About it, the website, and the
(https://github.com/Continuities/adarkroom) for the websiteCDQ News and Tips by Ken Miller
Hey RubyMotion folks, I'm going to start work on CDQ 0.2.0 soon, and I wanted
to give you a heads up as to what I'm going to be tackling:
- Callbacks: Structured way to perform actions when certain lifecycle events take place: create, update, delete, either for a specific object (say, on behalf of some controller code) or for all instances of a class.
- Friendly error messages: Core Data error messages are... cryptic. This would put a layer on top to make them easier to decipher.
- Easier Validations: Core Data lets you add simple validations on your schema, or custom ones in your model, but working with them in code is not easy or natural. This would create simple API for running builtin validations, and for defining custom ones.
You can see this list as it updates, and any future plans on the roadmap page on github:

If you have ideas you'd like to share (or even better, help out with) or you just have a question, reach out to me on Twitter, or email (ken@infinitered.com).
iOS Marketing Tip of the Week by Mark Rickert
The first screenshot you upload to iTunes Connect is the first impression a potential purchaser gets of your app. Along with your app's name, the first screenshot should be a good representation of what your app actually does.
What makes a great screenshot? Check out this artice from Dan Counsell of Realmac software (RapidWeaver, Clear, etc.) on how to design great App Store screenshots to set your app apart from the fray.
