Playing system sound without importing your own

Question

Is it possible to play already existing system sounds without importing your own?

Answer 1

adapted from @yannc2021

http://iphonedevwiki.net/index.php/AudioServices

if you want to use system sound in Swift

// import this
import AVFoundation

// add this method
required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

// declared system sound here
let systemSoundID: SystemSoundID = 1104

// to play sound
AudioServicesPlaySystemSound (systemSoundID)

This cocoa-only solution uses existing audio files to play sounds. This method can be used to play any sound file. AVFoundation.framework will have to be added to your frameworks. You will have to define or remove the macros I use which are self explanatory.

I added a category to AVAudioPlayer as follows:

AVAudioPlayer+.h

 #import <AVFoundation/AVAudioPlayer.h>

@interface AVAudioPlayer ( CapSpecs )
+ (AVAudioPlayer*) click;
+ (AVAudioPlayer*) tink;
+ (AVAudioPlayer*) tock;
+ (AVAudioPlayer*) withResourceName: (NSString*) aName;
@end

AVAudioPlayer+.m

 #import "AVAudioPlayer+.h"

@implementation AVAudioPlayer ( CapSpecs )
+ (AVAudioPlayer*) click {
    StaticReturn ( [AVAudioPlayer withResourceName: @"iPod Click"] );
}
+ (AVAudioPlayer*) tink {
    StaticReturn ( [AVAudioPlayer withResourceName: @"Tink"] );
}
+ (AVAudioPlayer*) tock {
    StaticReturn ( [AVAudioPlayer withResourceName: @"Tock"] );
}
+ (AVAudioPlayer*) withResourceName: (NSString*) aName {
    NSBundle* zBundle = [NSBundle bundleWithIdentifier: @"com.apple.UIKit"];
    NSURL* zURL = [zBundle URLForResource: aName withExtension: @"aiff"];
    (void) RaiseIfNil ( nil, zURL, ([SWF @"URL for %@",aName]) );
    NSError* zError = nil;
    AVAudioPlayer* zAudio = [[AVAudioPlayer alloc] initWithContentsOfURL: zURL error: &zError];
    RaiseError ( nil, zError, @"AVAudioPlayer init error" );

#ifdef DEBUG
    //  Apple records the console dump which occurs as a bug in the iOS simulator
    //  all of the following commented code causes the BS console dump to be hidden
    int zOldConsole = dup(STDERR_FILENO);   // record the old console
    freopen("/dev/null", "a+", stderr); // send console output to nowhere
    (void)[zAudio prepareToPlay];       // create the BS dump
    fflush(stderr);             // flush the console output
    dup2(zOldConsole, STDERR_FILENO);   // restore the console output
#endif

    return zAudio;
}
@end

This code plays apple system sound "Tock.aiff"..I believe you can play different system sounds using this

NSString *path = [[NSBundle bundleWithIdentifier:@"com.apple.UIKit"] pathForResource:@"Tock" ofType:@"aiff"];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:path], &soundID);
AudioServicesPlaySystemSound(soundID);
AudioServicesDisposeSystemSoundID(soundID);

List of all system sounds: iOSSystemSoundsLibrary

After you import AVKit, you can play all this sounds with:

AudioServicesPlaySystemSound (systemSoundID);
