Memory Leak NSXMLController and others (as a result of the Parser leak)

Pretime · June 2011

Hey Folks, just another issue, maybe you have another run on this one: solving one leak brings another one:

xmlcontroller.m


NSString *theContent = [currentNodeContent stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; //<-- 100% Memory Leak
[currentNodeContent setString:@\"\"];

if([elementName isEqualToString:@\"pos\"])
{
currentTabelle.place = theContent;
}
... .... .....

if([elementName isEqualToString:@\"team\"])
{
[table addObject:currentTabelle];
[currentTabelle release];
currentTabelle = nil;
[currentNodeContent release];
currentNodeContent = nil;
}

This just happens whenever the view disappears (i.e. tabbar) and another view gets loaded (with another XMLController) the view which throws a leak is the one that displays the content of the feed of the xmlparser.

tableview.m


self.xmlcont = [[[XMLController alloc] init] autorelease];

if ([content isEqualToString:@\"1. Bundesliga\"]){
if(pageNumber == 0){
[xmlcont loadXMLbyURL:@\"http://results.baseball-softball.de/extern/standing.php?l=12&xml\"];
} 
if(pageNumber == 1){
[xmlcont loadXMLbyURL:@\"http://results.baseball-softball.de/extern/standing.php?l=11&xml\"];
}
... .... .....

}

The View (aboth (tableview)) gets added by a scrollview, in reaction of another leak displayed in this scrollview, i think this is a chain-reaction.

Scrollview.m:


if (nil == controller.view.superview) { //<- 100% Leak
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * page;
frame.origin.y = 0;
controller.view.frame = frame;
[scrollView addSubview:controller.view];
}

I hope you can help me this time as good as the last time ;)!

thanx 2 all

Howdy, Stranger!
