【问题描述】：

我正在开发一个 iPad 应用程序。我们以 XML 格式获取数据。我使用NSXMLParser 进行解析，所有数据都打印到控制台。如何分别检索值？

另一个问题是如何检查 iPhone 中的内存泄漏？

IDK “检查内存泄漏”是如何出现的。正确管理内存，你不会有泄漏，繁荣。

使用TBXML进行解析

【参考方案1】：

你好，在发布之前做一些 r 和 D 很多帖子都可用，只需检查这个 link 它可能对你有帮助

在你的方法中

- (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];
