Having to submit an app update just for minor content changes is a huge pain. Especially with Unity. CloudPrefs provides a PlayerPrefs-like dictionary that's backed by Parse, and can be updated from the web. It includes an extension for NGUI's UILabel that will sync the label text to the value in the dictionary. It will default to PlayerPrefs when network access isn't available.

NativeUI is a Unity plugin I've been working on for a little while now. It allows you to display a native iOS view on top of Unity. It supports iOS 5 Storyboards, as well as the older XIB. It can be used to show a full screen view, such as a menu, or a smaller popover. 

It also wraps the message passing system, in both directions. Native code can pass messages into Unity, and Unity can pass messages back. In the example above, the "Load" button sends a message to Unity to load in the red particle system. 

Currently only iOS is supported, but Android support is going to be added soon (read: eventually). 

Also, it's free! 

For many of our apps, it'se critical that they be able to be downloaded over 3G. Unfortunately, the App Store limits 3G downloads to 50MB, which can be a struggle when trying to fit lots of 3D/media content into an app. The problem is that the IPA file generated by Xcode is not the same file that gets downloaded from the App Store. Apple does some encryption on their end once you submit your app, which typically adds 5MB or so (up to 13MB in one case!) to the IPA size. This means that when building your app, your actual size target needs to be anywhere from 35 to 45 MB instead of the full 50. 

App size = (executable from IPA) + (rest of IPA contents compressed)

You can estimate the App Store size by uncompressing the IPA file (it's just a zip), taking the executable out of it, and re-zipping everything else. Add the two together and that should be roughly your App Store size. In our testing it's been pretty close to accurate.

Not a very complicated process but still annoying to do manually. So, here's a script to do it for you!

After keeping it private for many months, I've decided to open source my Live Hub Remote app. It will almost certainly be rejected from the App Store for misusing the iPod controls, so I'm not going to bother. Instead, you can build and install it yourself. All it takes is a copy of Xcode, which is free on the Mac App Store. Just download the repository, open it up, and build. 

Seriously, it's terrible. What were they thinking? 

defaults write .GlobalPreferences com.apple.mouse.scaling -1

defaults write .GlobalPreferences com.apple.trackpad.scaling -1

I've been having tons of trouble building Python libraries (pycurl and hiredis specifically) lately, and I've finally figured out why. XCode 4 no longer supports building for PPC, so easy_install fails. The easy way to fix this is to do:

sudo env ARCHFLAGS="-arch i386 -arch x86_64" easy_install pycurl

But, this is a lot of extra overhead every time you want to install. To simplify this, just put the ARCHFLAGS into your .bash_profile:

export ARCHFLAGS="-arch i386 -arch x86_64"

However, we want this to carry over as sudo, so we'll add the following line to /etc/sudoers:

Defaults env_keep += "ARCHFLAGS"

This file is write protected (even as sudo?) so you'll get warnings when you try to save it. It should be okay though. I hope. Now you should be able to do a standard easy_install, and have it actually work. 

Well, the source has been up for a while, but it's finally polished enough for me to make a post about it. What is "it"? A little iPhone app I wrote which wraps the Dal FCS webcams. I'm not going to put it on the App Store unfortunately, as I'm not sure about using the streams/logos. Someone who knows about this, let me know! However, if you have Xcode and the iOS SDK you can build it yourself. The source is available on GitHub, here.
