Question

我正在开发一款iPad应用。我们将数据作为XML获取。我使用NSXMLParser进行解析，所有数据都打印到控制台。如何单独检索值？

另一个问题是如何检查iPhone中的内存泄漏？

你好在发帖之前做了一些r和D很多帖子都可以查看这个link它可以帮到你

在您的方法中

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict
{

    if([elementName isEqualToString:@"Result"])
    {
        //Initialize the array.
        arrXMLData = [[NSMutableArray alloc] init];
    }
    else if([elementName isEqualToString:@"Movieoftheweek"])
    {
        currentElementValue = [[NSMutableString alloc] init];
    } 
    else if([elementName isEqualToString:@"Movie_List_in_theater"])
    {
        currentElementValue = [[NSMutableString alloc] init];
    }}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    if(!currentElementValue)
        currentElementValue = [[NSMutableString alloc] initWithString:string];
    else
        [currentElementValue appendString:string];
    NSLog(@"Processing Value: %@", currentElementValue);
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    if([elementName isEqualToString:@"Result"])
        return;
    else if([elementName isEqualToString:@"Movieoftheweek"])
    {
        [arrXMLData addObject:currentElementValue];
    }
    else if([elementName isEqualToString:@"Movie_List_in_theater"])
    {
        [arrXMLData addObject:currentElementValue];
    }
    [currentElementValue release];
   }
