I get up to the bit where you open the xib and control click for the file owner but I don’t see what you have on your tutorial. Must have done something wrong but have tried it 3 times and get the same thing. Any ideas????

Джентльмен возвращается домой поздно вечером.Погода отвратительная:дождь,снег,ветер.У самого дома он замечает промокшую и продрогшую симпатичную девушку.Естественно,он,как истинный джентльмен,приглашает ее к себе домой,угощает кофе,укутывает пледом.Но гостья все время продолжает твердить,что ей холодно.Наконец,когда джентльмен уже не знает что и делать,она говорит: -А вот мой муж в таких случаях всегда согревал меня своим телом… -Простите,мадам,но не могу же я в такую погоду идти искать тело вашего мужа…

I’m not sure why the app crashes when I “Build and Go” the code from github, but I just tried it from the tutorial and it worked! (I tried the tutorial last night and ended up with a lot of errors — my fault I’m sure). Anyway, thank you very very much for posting this tutorial and the code — I am as much a beginner as is possible with app development and this helped me a great deal.

I am having the exact same problem as Jason. Downloaded the code, built and ran, simulator opens but the app crashes — “The application BickBoxx quit unexpectedly.” The report says ” ‘The application code must be 32 characters’.”

Hi Henry,

I downloaded the code from github, and opened with xcode. When I built and ran it in simulator, the app crashed with this error: “The application code must be 32 characters”.

Is the code working?

I try too replace the sound with my own and I change the code too my extension in the ViewController.m but nothing plays still! What are supported file types and how do I make a .AIFC file?

Hi, firstly thank you so much for this tutorial, it’s been the most helpful one I’ve found after hours of searching! I’ve completed the app as per the tutorial and now I’m learning how to customize it. My question is this: I’m trying to customize the sounds and I noticed in the above comments that for longer sound files you need to use Avaudio right? To use this would I just import it into the frameworks and change the code accordingly? I’m going to experiment with other techniques too. Thank you so much for writing this and giving me the confidence to try out something completely new!
Thanks so much for you help I really appreciate it!

how do you use this with a tab bar app?

i have created the tabs and screens, and added the relevant code, but when i press the button to play the sound, the app crashes out.

@Julia in the ViewController.m you can replace the CFSTR with the filename and the file extension. Not all files are supported.

Btw, how can you make the sound to play twice when you click it twice?

Press once: Thiing
Press twice now: Thii-Thiing
Press twice the way I want it: Thii-Thii-ng-ng

Can anyone help me with this?

I’m trying to replace one of the button sounds with my own sound, but nothing will play. Does my file need to be a specific type of file?

Great tutorial, but it breaks Apple’s design guidelines….SystemSound shouldn’t be used for game sounds.
