Question

I’m working on a piece of code that GETs a URL and parses the contents for data between a asset of tags. In this case, it’s looking for the code between and . When the URL body returned doesn’t contain those tags, the cullXML: method returns an empty array like this:

return [NSArray arrayWithObjects: nil];

I check to be sure that the returned array has objects with:

        if ( matchesXML.count ) {

In my debug code, I check twice. The first time, it works fine. The second time, just a couple lines later, it crashes. I can’t see why. The lines look the same to me.

What am I missing?

A bigger chunk of the code is included below. Thanks!

   if (self.newResults) {
        NSString *urlResult;
        NSArray *matchesXML;
        NSArray *match;
        NSDictionary *currentResult;
        NSMutableDictionary *results = [[NSMutableDictionary alloc] init];
        NSArray *returnedObjects;
        NSArray *dictionaryKeys;
        NSMutableArray *currentResultObjects;

        int i = 0;

        // determine tournament type, because the fields are different per type
        NSString *tournamentType;
        tournamentType = [[AFMethods tournamentTypeFromId:self.inputTournamentId] objectAtIndex:0];

        urlResult = [NSString stringWithFormat:@"%@", responseHandle];
        [responseHandle release];

        NSLog(@"urlResult retrieved: %@", urlResult);
        matchesXML = [AFMethods cullXML: urlResult forTag: @"matches"];

        NSLog(@"matches loaded: %@", matchesXML);
        NSLog(@"matchesXML.count %i", matchesXML.count);
        if ( matchesXML.count ) {
            NSLog(@"not nil");
        } 
        NSLog(@"just before tested");
        if ( matchesXML.count ) {
            NSLog(@"tested");

I found the issue!

It wasn’t crashing where I thought. It was a couple lines later. I was releasing an auto-released object. It must have been a left-over line from a previous organization of the code.

I removed the release and it’s working perfectly again.
