Stopping Sound and Controlling Volume

[starwarsdevwookie59]

I have an app that simply plays a short .wav file on the click of a button and would like it to also stop the sound at the click of another button and implement a slider for control of the volume. Im using the AudioToolbox/AudioServices file and my code for playing the sound looks like this:

- (IBAction)push {
NSString *tmpFileName = [[NSString alloc] initWithFormat:@"mario_09"];
NSString *fileName = [[NSBundle mainBundle] pathForResource:tmpFileName ofType:@"wav"];

SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:fileName], &soundID);
AudioServicesPlaySystemSound (soundID);

[tmpFileName release];

}

any help would be greatly appreciated. thanks much.

i had the same issue and added this just above the code for the next button that was pressed that needed to cancel any sound currently playing:

[soundEffect release];

now i can click button one and mid sound press button two and have sound 1 canceled and sound 2 played.

I think for you it will be soundID

- (IBAction)push {
NSString *tmpFileName = [[NSString alloc] initWithFormat:@"mario_09"];
NSString *fileName = [[NSBundle mainBundle] pathForResource:tmpFileName ofType:@"wav"];

SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:fileName], &soundID);
AudioServicesPlaySystemSound (soundID);

[tmpFileName release];

}

- (IBAction)stop {

[soundID release];
(ERROR SOUNDID UNDECLARED)

NSString *tmpFileName = [[NSString alloc] initWithFormat:@"mario_08"];
NSString *fileName = [[NSBundle mainBundle] pathForResource:tmpFileName ofType:@"wav"];

SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:fileName], &soundID);
AudioServicesPlaySystemSound (soundID);

[tmpFileName release];

}

I did this but i got the error listed above in all caps.

you need to declare soundID as an instance variable. when you declare it in the function its only available in that function. so create a instance variable at the top then you dont need to put SystemSoundID soundID; everywhere

SystemSoundID *soundID;

- (IBAction)push {
NSString *tmpFileName = [[NSString alloc] initWithFormat:@"mario_09"];
NSString *fileName = [[NSBundle mainBundle] pathForResource:tmpFileName ofType:@"wav"];


AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:fileName], &soundID);
AudioServicesPlaySystemSound (soundID);

[tmpFileName release];

}

- (IBAction)stop {

[soundID release];


NSString *tmpFileName = [[NSString alloc] initWithFormat:@"mario_08"];
NSString *fileName = [[NSBundle mainBundle] pathForResource:tmpFileName ofType:@"wav"];


AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:fileName], &soundID);
AudioServicesPlaySystemSound (soundID);

[tmpFileName release];

}
