iOS custom blocks using objective-c

Is it possible to create custom blocks using objective-c that others can use? Will anything similar be available for Android using java? Is there documentation available on creating custom blocks or calling external libraries on iOS?

The custom block function works the same across all platforms - are you finding that it doesn't work in iOS?

It's documented here

External library support will to iOS in the future, though you can always take the Xcode project and add the libraries in after the fact.

What I am really talking about is creating new block types that call custom Objective-C libraries through the normal drag and drop interface. For instance, will developers be able to make a block from an open source library that reads a QR Code and returns the text that was decoded? Or any other external library for that matter so that Stencyl app creators don't have to work at the Objective-C level - only the custom block/library creator needs to work at that level? Imagine how fast the functionality of Stencyl would be grow if Objective-C programmers could create and share new types of blocks. Suddenly Stencyl could become a general purpose graphical app development environment like App Inventor rather than just a game development tool.

Once you're able to link in external libraries from within StencylWorks, this will be possible. We already allow this for our Flash apps.

Very cool!
How far in the future do you expect that capability to become available? weeks? months? years?

I would say later this year - it's not particularly difficult to do, but we already have a lot on our plate right now and want to finish the things we have to do first.

Google online and you will find barcode generating related open source, but I don't think you can get barcode reading material, with which you can read a QR Code and return the text encoded. Most of them are commercial as this is more complicated than generating technology.
