工具类：

1、请求接口要用到的工具类：webservice

webservice.h

#import <Foundation/Foundation.h>
    #import "XMLParser.h"
    #import "WeiboSDK/WeiboSDK.h"
    @interface webservice : NSObject<MBProgressHUDDelegate>
    {
        MBProgressHUD *HUD;
    }
    -(NSDictionary *)insertCatalogWithJsonForJson:(NSURL*)strurl send:(NSDictionary *)sendinfo;
    -(TreeNode *)insertCatalogWithJson:(NSURL*)strurl send:(NSDictionary *)sendinfo;
    -(TreeNode *)insertCatalogWithJsondata:(NSURL*)strurl send:(NSData *)sendinfo;
    -(TreeNode *)insertCatalogWithJsonmul:(NSURL*)strurl send:(NSMutableDictionary *)sendinfo ;
    -(void *)getxmldata:(TreeNode *)node  receive:(NSMutableArray *)arrreceive  result:(NSMutableArray *)resultarry;
    @property (strong, nonatomic) IBOutlet UIView *fatherview;
    @property (nonatomic) bool show;
    @property (nonatomic) bool errorconnect;
    @end

webservice.m

    	// Do something usefull in here instead of sleeping ...
    	sleep(3);
    }
    
    
    @end

2、xml解析要用到两个工具类：XMLParser和TreeNode

XMLParser.h

#import <CoreFoundation/CoreFoundation.h>
    #import "TreeNode.h"
    @interface XMLParser : NSObject
    {
        NSMutableArray      *stack;
    }
    + (XMLParser *) sharedInstance;
    - (TreeNode *) parseXMLFromURL: (NSURL *) url;
    - (TreeNode *) parseXMLFromData: (NSData*) data;
    @end

XMLParser.m

#import "XMLParser.h"
    @implementation XMLParser
    static XMLParser *sharedInstance = nil;
    // Use just one parser instance at any time
    +(XMLParser *) sharedInstance
    {
        if(!sharedInstance) {
            sharedInstance = [[self alloc] init];
        }
        return sharedInstance;
    }
    // Parser returns the tree root. You may have to go down one node to the real results
    - (TreeNode *) parse: (NSXMLParser *) parser
    {
        stack = [NSMutableArray array];
        TreeNode *root = [TreeNode treeNode];
        root.parent = nil;
        root.leafvalue = nil;
        root.children = [NSMutableArray array];
        [stack addObject:root];
        [parser setDelegate:self];
        [parser parse];
    //    [parser release];
        // pop down to real root
        TreeNode *realroot = [[root children] lastObject];
        root.children = nil;
        root.parent = nil;
        root.leafvalue = nil;
        root.key = nil;
        realroot.parent = nil;
        return realroot;
    }
    
    - (TreeNode *)parseXMLFromURL: (NSURL *) url
    {
        TreeNode *results;
    //    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
        NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
        results = [self parse:parser];
    //    [pool drain];
        return results;
    }
    - (TreeNode *)parseXMLFromData: (NSData *) data
    {
        TreeNode *results;
    //    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
        NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data];
        results = [self parse:parser];
    //    [pool drain];
        return results;
    }
    // Descend to a new element
    
    - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)
    namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
    {
        if (qName) elementName = qName;
        TreeNode *leaf = [TreeNode treeNode];
        leaf.parent = [stack lastObject];
        [(NSMutableArray *)[[stack lastObject] children] addObject:leaf];
        leaf.key = [NSString stringWithString:elementName];
        leaf.leafvalue = nil;
        leaf.children = [NSMutableArray array];
        [stack addObject:leaf];
    }
    // Pop after finishing element
    
    - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
    {
        [stack removeLastObject];
    }
    // Reached a leaf
    
    - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
    {
        if (![[stack lastObject] leafvalue])
        {
            [[stack lastObject] setLeafvalue:[NSString stringWithString:string]];
            return;
        }
        [[stack lastObject] setLeafvalue:[NSString stringWithFormat:@"%@%@", [[stack lastObject] leafvalue], string]];
    }
    @end

    {
        TreeNode        *parent;
