Game Center UI

I downloaded a game called Cloud Breaker this morning.  I was pleasantly surprised by it.  What really stuck me though was the Game Center integration.  I haven’t seen a game that just used the APIs and displayed their own UI.  I always wondered why people didn’t do this or why there isn’t an open-source project […]

Free To Play… Before Buying

Recently I became acquainted with app.io.  It allows you to run a simulator build of your app within an iframe on a webpage.  This way you can let users play with your app before purchasing it.  You can see the results of embedding Buttermilk below. Of course the frame rate is WAY LOW (but it is […]

Implementing a Parental Gate

Last blog entry I told you about my difficulties getting Buttermilk approved for the new KIDS section in the App Store.  Well, even after I implemented the Parental Gate screen like I had seen in “Cut The Rope” I was still rejected.  However… I don’t think Apple understood what I was doing and so I [...]

Childish Behavior

So with iOS 7 Apple is introducing a KIDS section in the App Store. Specifically they said Well… I wanted to get in on the action and see if the new category could give some of my games more visibility.  So I resubmitted Buttermilk The Bouncing Baby Goat as a new version and supplied a [...]

Free At Last! NOT!

I wanna show you 2 graphs.  Mind you, I’m revealing everything about my financials here just to be totally transparent and realistic. Do you see anything that stands out on that graph?  Ok… maybe not yet… let me show you the 2nd one. Yikes!  You’re probably wondering why my downloads all the sudden dropped off [...]

Update Often

Doug Davies

This weekend I had to fix a null pointer exception in one of my games I hadn’t updated in 2 years.  I noticed under iOS 7 that there was an unrevealed (although some people had reported it) problem with my DDGameKitHelper code during score synching.  Someone had submitted a patch for it, but I just [...]

Xcode is dead! Long live… Corona?

Doug Davies
funkyvisions.com

I will probably never use Xcode again (unless Apple forces me to — and at that point I’ll probably just quit developing for iOS).  And this is from someone who has been using Objective-C and Interface Builder since 1993… yes you heard me… 20 years ago I started using Steve Jobs’ vision of how development [...]
