Building stuff! I’ve been working on track recording and layering lately. This episode I’m talking about the complexities involved in non-destructive layering, and how I’m making sure everything’s rock-solid via unit testing.

Not dead, you guys. Just working on something I’m not quite ready to show you yet. It’ll be worth the wait, though.

Back home again, and working on Loopy Masterpiece’s action infrastructure: this is how Masterpiece’s universal action triggering and sequencing is probably going to function, allowing for a non-destructive workflow and performance automation, among other cool things.

I’ve been doing some work under the hood this week: working on Loopy Masterpiece’s data model and figuring out how sessions are going to be stored on disk. The answer: Core Data.

Some more progress on Masterpiece’s prototype, although I got a little tiny bit lost on a tangent. This week I’m talking about graphics performance and reacquainting myself with OpenGL, and affordance in animation. Also, I found an amusing little piece of memorabilia.

Well, this week didn’t go quite as planned. I think I broke my own spirit. Oh well! Maybe next week.

An iTunes Connect screenshot management workflow

By Michael Tyson | Published: March 24, 2015

Ugh – iTunes Connect is really annoying to use when it comes to screenshots. There’re some third party tools out there, but it was still too hands-on for my workflow.

So I wrote a little script that does the stuff I want. I have a Sketch document that exports all the screenshots, and the script updates the iTunes Connect metadata XML appropriately.

In case it’s useful to anyone else:

Usage:

  1. Work on screenshots

  2. Setup:

    alias iTMSTransporter="/Applications/Xcode.app/Contents/Applications/Application\ Loader.app/Contents/MacOS/itms/bin/iTMSTransporter"

  3. Grab latest ITMS data:

    iTMSTransporter -m lookupMetadata -u [email protected] -p password -vendor_id APPVENDORID -destination YourApp.itmsp

  4. Open up the metadata.xml and remove the fields you don’t want to change – this is probably going to be the currently-live version, and maybe the product info at the bottom.

  5. Export all the screenshots into the itmsp package folder

  6. Run this tool (update_itmsp_screenshots.php YourApp.itmsp)

  7. Check that everything looks okay

  8. Verify

    iTMSTransporter -m verify -u [email protected] -p password -f YourApp.itmsp

  9. Upload

    iTMSTransporter -m upload -u [email protected] -p password -f YourApp.itmsp

I’m back, and doing some prototyping this week. Look! It moves!

Stick around (and be sure to subscribe) if you’re interested in trying out the prototype app when it’s ready.
