app freezes when I press button

[Karts9]

Hi I am new to programing, and I have been working on an app that plays a random sound when you press a button. No I'm not making another fart app.
The program does not show any errors, However when the app loads, on both the sim and device, when i press the button it just stays blue and freezes. Any help would be very appreciated. here is the code Im using:


- (IBAction)playSoundid)sender
{
int randomNumber = arc4random() % 25 + 1;

NSString *tmpFileName = [[NSString alloc] initWithFormat:@"sound%d", randomNumber];
NSString *fileName = [[NSBundle mainBundle] pathForResource:tmpFileName ofType:@"aif"];

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

[tmpFileName release];
[fileName release];
}


I know its probably something simple with my code but once again I am new to programing and am still coming to terms with this language.

Don't release fileName. The only time you should release is if you did an alloc, copy, new, or retain.

ok i got rid of the filename release, but I think i have another issue somewhere. I noticed a messeage that said:" __TERMINATING_DUE TO_UNCAUGHT_EXEPCTION__"

Any Idea on what I need to do to fix this??

[BrianSlick]

No idea without code. Add some log messages to figure out where it is dying.

Does This help?

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:]: nil string parameter'

could it have something to do with this? This is the main.m file

#import <UIKit/UIKit.h>

int main(int argc, char *argv[]) {
    
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil);
    [pool release];
    return retVal;
}

Nope. The important part is right here in your error message:

 -[NSURL initFileURLWithPath:]: nil string parameter'

Whenever you are given a method name, figure out where you are doing that. The 'nil string parameter' parts means that the string you are using for the path is actually empty. You need to fix that.

Oh man I can't believe what the issue was, it was this part here:

NSString *tmpFileName = [[NSString alloc] initWithFormat:@"sound%d", randomNumber];

My files start with a Capital 'S' for sound and I had put a lower case 's' in the code, it's working now. Thanks for your help.
