TouchXML and EXC_BAD_ACCESS

verbatimbot · 06-09-2011, 08:18 AM

Hello,

I am new to objective-c and iphone programming and I have ran into the following problem with TouchXML. The value is successfully parsed and no exception is thrown within callService method, but it throws EXC_BAD_ACCESS error anyways.

If I comment out the last line [nodes release] it has no error in that case, but I am worrying about the memory leaking.

Code:

-(IBAction) callService:(id)sender
{
    NSURL *url = [NSURL URLWithString:@"http://someurl.com/api/getbyid/40"];
    NSData *XMLData   = [NSData dataWithContentsOfURL:url];
    CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease];
    
    NSArray *nodes = NULL;
    nodes = [doc nodesForXPath:@"//StoreDetails" error:nil];
    
    for (CXMLElement *node in nodes) {                
        txtOutput.text = [[node nodeForXPath:@"Name" error:nil] stringValue];              
    }
    
    [nodes release];
    
}
