copied!<p>I would wrap the sound into a subclass of <code>NSObject</code> and make it a self contained unit. A sound would have operations like <code>play</code>, <code>stop</code>, <code>pause</code>, and accessors like <code>isPlaying</code>, etc.</p> <p>Then to make it even more generic I would search for all files matching the pattern <code>"*.wav"</code> and then for each matched file name, initialize a <code>Sound</code> object with that file name, and add it to an array.</p> <p>Here's what I imagine the Sound object would look like:</p> <pre><code>@interface Sound : NSObject @property FMOD::Sound *sound; - (id)initWithSoundFilePath:(NSString *)path; - (void)play; - (void)stop; @end @implementation Sound - (void)dealloc { // free the memory occupied by the sound pointer here } - (id)initWithSoundFilePath:(NSString *)path { self = [super init]; if (self) { result = system->createSound(path, FMOD_SOFTWARE | FMOD_LOOP_NORMAL, NULL, &sound); ERRCHECK(result); } return self; } - (void)play { FMOD_RESULT result = FMOD_OK; result = system->playSound(FMOD_CHANNEL_FREE, sound, false, /* What is this wob? */); ERRCHECK(result); } - (void)stop { FMOD_RESULT result = FMOD_OK; result = /* What is this wob */->stop(); ERRCHECK(result); } @end </code></pre> <p>So there you have it. A sound is nicely encapsulated now. I found this <a href="https://stackoverflow.com/questions/499673/getting-a-list-of-files-in-a-directory-with-a-glob">answer</a> helpful in finding a list of all files in a certain directory matching some criteria. You could use that in your view controller to automatically generate all relevant Sound objects and add it to an array.</p> <pre><code>- (NSArray *)getPathsOfSoundFiles { NSString *rootPath = [[NSBundle mainBundle] resourcePath]; NSFileManager *fm = [NSFileManager defaultManager]; NSArray *files = [fm contentsOfDirectoryAtPath:rootPath error:nil]; NSPredicate *soundFileFilter = [NSPredicate predicateWithFormat:@"self ENDSWITH '.wav'"]; NSArray *soundFilePaths = [files filteredArrayUsingPredicate:soundFileFilter]; return soundFilePaths; } </code></pre> <p>Ok, now that you can retrieve the paths to all .wav files, the next step is to initialize them in your <code>viewWillAppear</code> or whatever method makes most sense.</p> <pre><code>- (void)viewWillAppear:(BOOL)animated { NSArray *paths = [self getPathsOfSoundFiles]; NSMutableArray *sounds = [NSMutableArray array]; for (NSString *path in paths) { Sound *sound = [[Sound alloc] initWithSoundFilePath:path]; [sounds addObject:sound]; } self.sounds = sounds; } </code></pre> <p>And with the sounds array setup, playing and stopping a given sound becomes rather easy. Use could create a method that takes an index into the array, or maybe a <code>Sound</code> object itself and does the job.</p> <pre><code>- (void)playSoundAtIndex:(NSUInteger)soundIndex { Sound *sound = [self.sounds objectAtIndex:soundIndex]; [sound play]; } - (void)stopSoundAtIndex:(NSUInteger)soundIndex { Sound *sound = [self.sounds objectAtIndex:soundIndex]; [sound stop]; } </code></pre>
