    <p>I'm trying to put together a little app to kind of learn some basics of iOS development so forgive me if this is basic. I've looked at quite a few threads but I've got a couple questions that are specific to this app I think. </p> <ol> <li><p>I've seen a couple different ways to play audio when a button is pressed. One involves the "CFBundleRef" (<a href="https://stackoverflow.com/questions/884452/how-to-play-iphone-tap-sound">How to play iPhone tap sound?</a>) and the other "AVAudioPlayer" (<a href="https://stackoverflow.com/questions/11525942/play-audio-ios-objective-c">Play Audio iOS Objective-C</a>). How do I know which to use and when to use each appropriately? </p></li> <li><p>I've got the audio working currently using the first option, but I can't seem to figure out how to get the sound to stop when another button is pressed. How can I do this?</p></li> <li><p>Is there an easier way to link 15 sounds / buttons together other than what I've done? </p></li> </ol> <p>Here's the .m file:</p> <pre><code>#import "animalsViewController.h" @interface animalsViewController () @end @implementation animalsViewController -(IBAction) boom;

    1. COIts a good question but the way you done it in post 1 is also perfectly fine. especially as its simply cut and paste after the initial code!! and then simple to drag and drop your buttons to the IB points!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
