Hi, I am using NSXMLParser with XML data from a share point server.
If i download more than ten rows of xml at a time it crashes at AppDelegate.h "EXC_BAD_ACCESS".... in the log it says...
"error while killing target (killing anyway): warning: error on line 2184 of "/SourceCache/gdb/gdb-1708/src/gdb/macosx/macosx-nat-inferior.c" in function "void macosx_kill_inferior_safe()": (os/kern) failure (0x5x)"
Also if i include any of the commented out attributes (see code), with even just one row of xml applied, it will also crash.
I can run to a break point just before the dealloc with 20+ rows (the most i have to test) and all the attributes included and I get NO crash.
When I run "Analyze" there are no leaks.
This is parse 6 in a process of 7 separate parses of xml lists. In the end I will need to parse at least 80 rows in this instance .. can someone tell me what i am doing to cause this?
Thanks.
I have included what code i think is relevant.. if you need more just ask.
Code:
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
//NSLog(@"DONE. Received Bytes: %d", [webData length]);
//NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
//NSLog(@"theXML: %@",theXML);
NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil];
[NSURLCache setSharedURLCache:sharedCache];
[sharedCache release];
xmlParser = [[NSXMLParser alloc]initWithData:webData];
[xmlParser setDelegate: self];
[xmlParser parse];
[webData release];
}
