I have an App in which I record the sound files and store it in apps Document Directory.

Please look at the following code.

//Get the Document directory path.
 #define kDOCSFOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]

//Delete files by iterating items of the folder.
NSFileManager* fm = [[[NSFileManager alloc] init] autorelease];
NSDirectoryEnumerator* en = [fm enumeratorAtPath:kDOCSFOLDER];    
NSError* err = nil;
BOOL res;

NSString* file;
while (file = [en nextObject]) {
            // Date comparison.
    NSDate   *creationDate = [[fm attributesOfItemAtPath:file error:nil] fileCreationDate];
    NSDate *yesterDay = [[NSDate date] dateByAddingTimeInterval:(-1*24*60*60)];

    if ([creationDate compare:yesterDay] == NSOrderedAscending)
    {
        // creation date is before the Yesterday date
        res = [fm removeItemAtPath:[kDOCSFOLDER stringByAppendingPathComponent:file] error:&err];

        if (!res && err) {
            NSLog(@"oops: %@", err);
        }

    }

}
