When projects collide…

September 12, 2013 Leave a comment

The iPhone/iPad app I am developing is for live music use (not giving away any details just yet since I am sure any reasonable iPhone developer could knock up the same app in a couple of days and beat me to the finish line!) which means your hands are not so free. My original idea was to use a blue tooth connected foot pedal that I already happen to have (Airturn BT-105) to control the app. However it occurred to me that it would be pretty simple to add a blue tooth shield to an Arduino, hook up a few switches and make my own blue tooth enabled stomp box to control my app, plus I could have more than the two switches my current pedal has.

So, once the current Arduino project is done I’ll be starting on creating a blue tooth enabled stomp pedal to control this app and looking at blue tooth enabling my app to work with my custom pedal.

Back to the iPhone project

September 11, 2013 Leave a comment

The Arduino project is on hold because I am waiting for parts to arrive which appear to be on a VERY slow boat from Thailand so I decided to get back to my iPhone project.

My iPhone app (which will be mainly an iPad app when it is done) currently has three view controllers. I guess you can think of these as logical screens. Each one has it’s own implementation file (class) and when I originally wrote things, just to get it all going I used a lot of global variables to share data between the view controllers. This got messy really quickly so I’ve been reworking the code over the past couple of weeks to get rid of the global variables and pass data between the view controllers the ‘proper’ way.

I also need to make the app support device rotation as well as both iPhone and iPad devices so for no particular reason I chose to attack the device rotation topic first. So far it is proving to be an interesting challenge to make all my view controllers¬† work correctly since only the currently displayed VC receives the orientation change messages so any hidden VC has to check the orientation when it is redisplayed and reconfigure the screen to match the current orientation. Let’s just say that this part of the project is still a ‘work in progress’!

I have managed to sketch out what I want the main interface to look like but all the current work is just to get to the point where I can actually implement the main app function and has nothing to do with the actual ‘guts’ of the app.

Oh, and now we have new devices (no doubt with new physical screen sizes) and a new OS to contend with as well.

Still, it keeps me off the streets at night!
