I am I trying to learn proper memory management and have question: In the
following example, which objects am I responsible to release?
- (void) viewDidLoad{
NSString *tempStr = nil;
NSString *filepath = [[NSBundle mainBundle] pathForResource:@"filename"
ofType:@"xml"];
NSData *xmlData = [NSData dataWithContentsOfFile:filepath];
NSMutableString *xqueryStr = [NSMutableString
stringWithFormat:@"/data/title/@number"];
NSArray *resultNodes = PerformXMLXPathQuery(xmlData, xqueryStr);
NSEnumerator *e = [resultNodes objectEnumerator];
id object;
while (object = [e nextObject]) {
for (NSString *key in object){
tempStr = [[object objectForKey:key]
stringByTrimmingCharactersInSet:[NSCharacterSet
whitespaceAndNewlineCharacterSet]];
if ([tempStr isEqualToString:@"number"] ) {
}else {
// do something here
}
}
}
}
Thanks,
Phil
