Got memory leak while parsing large xml files from url using TBXML with ARC on

Question

I am using TBXML to parse XML files from an url and I have ARC on. But I got memory leak for the following code:

- (void)readXmlFromUrl:(NSString*)url
{
    NSURL *aUrl = [NSURL URLWithString:url];
    NSData *data = [[NSData alloc] initWithContentsOfURL:aUrl];
    TBXML *tbxml = [[TBXML alloc] initWithXMLData:data];
//    data = nil;
//    NSLog(@"Reading from %@", url);
    // If TBXML found a root node, process element and iterate all children
    if (tbxml.rootXMLElement) {
        NSLog(@"Root Found");
        [self traverseElement:tbxml.rootXMLElement];
    }

//    data = nil;
//    aUrl = nil;
//    tbxml = nil;
//    NSLog(@"Retain count for TBXML %d", tbxml.retainCount);
}

I attached an image of memory leak. Thanks in advance enter image description here

Are you sure you're building with ARC when running the static analyzer? ARC might only be turned on for some configurations, but Analyze uses a different one. — Vincent Gable, Sep 17 '12 at 22:19

Not a leak but likely a bug in the static analyzer.

He's using ARC, so no explicit autorelease is needed. – Jon Shier Sep 17 '12 at 22:07

ah yes, why would arc ever show a warning like that - ARC == not my job to release. point taken. So glad I dont use ARC. – deleted_user Sep 17 '12 at 22:11
