In my project i have implemented multiple service and getting response. Among that one WSDL service that returns one data set as a response,
+ (id)deserializeAsDictionary:(CXMLNode*)element { NSLog(@"deserializeAsDictionary = %@, children: %d", element.stringValue, [element childCount]); if([element childCount] == 1) { CXMLNode* child = [[element children] objectAtIndex:0]; if([child kind] == CXMLTextKind) { NSLog(@"child %@ added", [child stringValue]); return [[[element children] objectAtIndex:0] stringValue]; } } NSMutableDictionary* d = [NSMutableDictionary dictionary]; NSInteger i = 1; NSString *objKey; for(CXMLNode* child in [element children]) { id v = [Soap deserialize:child]; if(v == nil) { v = [NSNull null]; } else { if([[child name] isEqualToString:@"(null)"]) { objKey = [NSString stringWithFormat:@"%@",[child stringValue]]; } else if([[child name] isEqualToString:@"key"] || [[child name] isEqualToString:@"value"]) { objKey = [NSString stringWithFormat:@"%@",[child name]]; } else { objKey = [NSString stringWithFormat:@"%@%d",[child name],i++]; } } [d setObject:v forKey:objKey]; NSLog(@"child %@ added", objKey); } return d; } soap class will use this method to convert that data set into dictionary. Its working perfectly in IOS 5 but its not working in ios 6. Application will crash in ios 6 and through error as " CXML copy with zone "Please help me to fix this issue.
