An iTunes Connect screenshot management workflow

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

Searching iOS header files with Xcode

I’m often having to grep through various iOS frameworks in search of error codes that appear (“What the bloody hell does -10867 mean?”). This can be a bit annoying – especially while working with Core Audio – so I put together an Alfred workflow that does it for me.

Here it is – type “hs” (short for “header search”) then the text you want to search for, and it’ll give you matching results. Hit enter to open that file:line combination in Sublime Text, or edit the action script to work with the editor of your choice.

Encrypting and decrypting text with Alfred 2

Here’s a couple of Alfred 2 workflows that implement encryption and decryption via AES256, useful for doing things like sharing passwords.

Select some text (or copy it to the clipboard), and hit the encryption hotkey, and you’ll be prompted for a password; the encrypted contents will be copied to the clipboard.

Then when the recipient has the encrypted text, select or copy it, hit the decryption hotkey, and the original password will be requested. Then, the original text will be displayed and copied to the clipboard.

I ♥ Alfred: Code execution extensions

ExtensionI’m a really big fan of Alfred, and lately I’ve found it really useful for running tiny little snippets of code — whether it’s to quickly URL decode a string, or remind myself of how C integer-to-float conversion behaves, I find myself using these little extensions I put together quite frequently.

Here’re two workflows I use to run PHP code (one which just executes it and shows the result in Growl, and one which copies the result to the clipboard), and a workflow that runs a snippet of C code. Of course, it wouldn’t take much to make workflows for many other languages, too.

Now with live results! Hit enter to copy result to clipboard.

Uploading to TestFlight with a few keystrokes, using Alfred

TestFlight IconHere’s a cute little Alfred extension I put together today that uploads a file to a TestFlight team for you, after prompting for build notes.

You’ll wanna edit the extension to put in your API key and Team ID, then just select a file in Alfred, type ‘testflight’ (or an abbreviation thereof) and enter, then enter a build summary, and off it goes. Result will appear in Growl.

Supporting WordPress shortcodes and captions in MarsEdit preview

I noticed that WordPress these days uses a shortcode to define image captions, of the form:

[caption id="" align="aligncenter" width="630" caption="Image title goes here"]<img src="http://domain.com/imgpath/../image.jpg" width="630" height="420" />[/caption]

I’ve recently redone our blog template at Technomadics, and while setting up the new preview template in MarsEdit, thought I’d take a stab at implementing support for captions, too, via some javascript in the template.

I was successful! Here’s how I did it:

Added the following to the “head” section:

<script type="text/javascript">
var prior_content;
function watch_for_changes() {
  var check = function() {
    var elt = document.getElementById('content');
    if ( elt.innerHTML != prior_content ) {
       elt.innerHTML = apply_filters(elt.innerHTML);
	   prior_content = elt.innerHTML;
    }
    setTimeout(check, 100);
  };
  setTimeout(check, 100);
}
 
function apply_shortcode(source, name, callback) {
   return source.replace(new RegExp('\\[' + name + '\\s*([^\\]]*)\\]((.|[\s\n])*?)\\[/' + name + '\\]', 'g'),
                         function(match, paramString, content) {
                           params = new Object();
                           reg = /([a-z]+)="((:?="[^"]+"|[^"])*)"/gi;
                           while ( (match = reg.exec(paramString)) != null ) {
                             params[match[1]] = match[2];
                           }
                           return callback(params, content);
                         });
}
 
function apply_filters(html) {
  html = apply_shortcode(html, "caption", function(args, content) {
     return '<div '+
               'class="wp-caption ' + (typeof(args.align) != 'undefined' ? args.align : '') + '" '+
               'style="width: ' + args.width + 'px;">' + content +
             '<p class="wp-caption-text">' + args.caption + '</p></div>';
  });
 
  return html;
}
</script>

…changed to ‘body’ tag to…

<body onload="watch_for_changes();">

…And wrapped a div around the main “#body#, #extended#” content with an id of content:

<div id="content">
#body#
#extended#
</div>

Basically, it polls the content area for changes, and when triggered, runs it though a filter. The above is extensible, and by adding additional “apply_shortcode” calls from “apply_filters“, more shortcodes can be simulated.

Fixing Xcode 4’s symbolicate utility to get comprehensible crash logs

‘symbolicatecrash’ is the Developer Tools utility which replaces all those meaningless addresses from crash logs with actual symbol names and source code references. It lives at some obscure folder within /Developer – use find to dig it up and symlink it into /usr/local/bin if you wanna use it conveniently from the command line.

Anyway, after plenty of frustration, I noticed some chatter about the damn thing being busted in Xcode 4. Figures!

There’s an alternate third party version on GitHub, but this didn’t really help me – I still got inscrutable errors, so I took a look at the original.

The version that comes with Xcode 4 appears to have some problems distinguishing, say, an iPhone Simulator build of the app from a native build sitting in the Archives folder. I’d just see an error about otool and some binary living in the iPhone Simulator folder.

Digging into the errant symbolicatecrash source, I noticed that the code that finds the executable path tests each candidate using otool, but doesn’t seem to be able to comprehend the output from otool caused by running it on the wrong architecture.

So, replacing the rather unhelpful ‘die’ statement on line 323:

die "Can't understand the output from otool ($TEST_uuid -> '$otool -arch $arch -l $path')";

With a “No, it ain’t this executable” response:

return 0;

…solves the problem immediately. Now I can drag crash logs straight into the Organizer in Xcode, and it’ll symbolicate correctly.

Objective-C + Cocoa on the Command Line

Sometimes there’s just one tiny snippet of Cocoa code that you want to test — maybe to find out the output of NSDateFormatter for various cases, testing out some text replacement routine, or testing out some image drawing code.

It’s often too much trouble to create a new XCode project and set up the framework to do one simple test, which is why I put together this little shell script that lets you run Cocoa code from the command line:

$ runcocoa 'NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease]; [formatter setDateFormat:@"d MMM, h:mm a"]; NSLog(@"%@", [formatter stringFromDate:[NSDate date]]);'

2011-02-23 20:02:10.313 runcocoa-output[28025:903] 23 Feb, 8:02 PM

You have full access to all Cocoa libraries, and in iOS mode, access to most iOS stuff too, straight from the command line.

Update: This is now available as a GitHub project Read More »
