It allows you to render your ActiveRecord objects as plists (among other things):

def show
  @post = Post.find(params[:id])

  respond_to do |format|
    format.xml   { render :xml => @post }
    format.plist { render :plist => @post }
  end
end

Jeena was kind enough to let me know he “stole” my old Jsonifier plugin (github) code in plistifier.

Save it into ~/Library/Application Support/Xcode/Color Themes/, restart Xcode, and open its Preferences. You will be able to pick the Railscasts Color Theme in the Fonts & Colors tab.

I dug this theme up after realizing that I haven’t actually saved the Railscasts theme I’d replicated from several months ago and was too lazy to set up another one in my other Mac.

Koen Van Der Auwera did a similar theme too so if you find that mine doesn’t work so well (I’ve only used it for Cocoa Touch development, not at all for developing Mac apps), scoot over to his blog post.

Anyway, I submitted it to the iPhone App Store for approval as a free app and named it Singtel Data Usage. No points for creativity with the name but I thought it’d be nice to know exactly what the app did from just reading its name. After one keyword rejection (which was unfounded but I wasn’t going to argue with the app reviewers), it finally got approved a few days ago.

Yeah that’s what it looks like. I stole part of the design from another iPhone app – can anyone guess which one? I think I spent 80% of development time changing the design over and over again, tweaking font sizes, and agonizing over which icons to use.

Thanks to folks on Twitter (I’m @chuyeow – do follow me if you’re reading my blog), word got around and by the 3rd day of it being approved, my app was the Top Free app on the Singapore App Store. Going to take a time out for the vanity shot:

A similar app, iBBOM, was approved around the same time but I believe I got a head start because of all the awesome people on Twitter who retweeted my tweet and the kind folks who gave glowing reviews on the App Store (thanks especially to Andy Croll for the 1st review). iBBOM actually looks much better than my app (I can’t help tweeting about it) and works perfectly (only thing I don’t like are the ads). I believe I couldn’t have gotten to the top of the App Store without the guys and gals who spread the word on Twitter.

On to the not so fun part of this post. Yet another similar app, SG BBOM, was pulled from the App Store by Singtel (the telco) recently so I’m expecting to hear from Singtel really soon. We shall see.

In the meantime, if you own an iPhone and have a Singtel data plan, do check out my app (App Store link) and give an honest review on the App Store. If you’ve already downloaded it, I’d like to know what you think in a review as well. Thanks!

I attributed it to the recent jailbreak (I’ve already removed the jailbreak trying to figure out this problem) at first. I only realized something was really wrong when the iPhone’s battery started draining while it was charging via USB!

Looking around on teh interwebs, I managed to solve it (easily!) by following the suggestions from this thread at the Apple support forums. Here’s what worked for me:

1. Go to Settings on your iPhone.
2. Turn Notifications off. I’m not sure if this is necessary but did so just in case.
3. Go to Mail, Contacts, Calendars and delete all your accounts (I deleted even Calendar accounts just in case). You may want to write down or backup your account settings first.
4. Go to Fetch New Data (also in the same Mail, Contacts, Calendars settings) and make sure Push is Off.
5. It’s probably not necessary but you may want to restart your iPhone (power it on and off) here.
6. Add back all your accounts. You can turn Push back on Fetch New Data now.
7. You can also turn Notifications back on if you wish.

It seems like the iPhone 3.0 OS update has a bug where email accounts with active push notifications were set to keep fetching new email even if push is turned off explicitly. Hopefully this post will help solve your battery problems, if not, you’ve gotta keep looking – the Apple iPhone Support forums is a good place to start.
