【问题描述】：

我正在处理soap请求和响应..我能够发出服务器请求并且我得到服务器响应，我在uialertview消息上解析，但是当我试图加载它时在表格视图上，我无法用字符串填充数组，所以请帮帮我

下面是我的代码

#import "SoapTableViewController.h"


@implementation SoapTableViewController

@synthesize customerArray;
@synthesize webData;
@synthesize dict;

- (id)initWithStyle:(UITableViewStyle)style

    self = [super initWithStyle:style];
    if (self) 
        // Custom initialization
    
    return self;

    "<soap:Body>\n"
    "<GetCustomers xmlns=\"http://www.fashionize.ca/\" />\n"
    "</soap:Body>\n"
    "</soap:Envelope>\n";       

    NSURL *url = [NSURL URLWithString:@"http://www.fashionize.ca/Service1.asmx"];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue: @"http://www.fashionize.ca/GetCustomers" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

    if( theConnection )
    
        webData = [[NSMutableData data] retain];
    
    else
    
        NSLog(@"theConnection is NULL");
    




-(void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *) response 

    webData =[[NSMutableData data]retain];
    [webData setLength: 0];

                        encoding:NSUTF8StringEncoding];
    //---shows the XML---
    NSLog(theXML);
   // [self parseXml:theXML];
    [theXML release];

        NSLog(soapResults);        
        elementFound = FALSE;
        UIAlertView *alert = [[UIAlertView alloc] 
                              initWithTitle:@"Customer Name!" 


                              message:soapResults

在这里你可以看到我的客户数组是空的..所以朋友和极客请告诉我哪里出错了..

感谢和问候 兰吉特

【参考方案1】：

我没有看到您的客户数组的分配？如果它没有内存，则无法添加它，这会暗示为什么它是空的。

customerArray = [[NSMutableArray alloc]initWithCapacity:0];

【讨论】：

嗨 louie 感谢您的回复...我写了您的代码行..但它也显示数组是空的..请帮帮我

【参考方案2】：

这可能会对您有所帮助。在parserDidEndDocument:(NSXMLParser *)parser 中重新加载您的表格。

-(void)parserDidEndDocument:(NSXMLParser *)parser
[reload tblView];
