我在我的应用中使用SOAP webservices。我使用以下语句（.m文件）发出请求：
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *soapMsg =
[NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance>\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema>\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/>\"><soap:Body><retLoca xmlns=\"http://www.ctrlbase.nl/cbawebapp>\"><tcUser>112</tcUser></retLoca></soap:Body></soap:Envelope>"];
NSURL *url = [NSURL URLWithString:
@"http://www.ctrlbase.nl/cbawebapp/getLoca.asmx>"];
NSMutableURLRequest *req =
[NSMutableURLRequest requestWithURL:url];
NSString *msgLength =
[NSString stringWithFormat:@"%d", [soapMsg length]];
[req addValue:@"text/xml; charset=utf-8"
forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://www.ctrlbase.nl/cbawebapp/retLoca>"
forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength
forHTTPHeaderField:@"Content-Length"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];
HUD = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
HUD.dimBackground = YES;
HUD.labelText = @"Ophalen van gegevens";
HUD.delegate = self;
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if( theConnection )
{
webData = [NSMutableData data];
}
else
{
NSLog(@"theConnection is NULL");
}
}
-(void) connection:(NSURLConnection *) connection
didReceiveResponse:(NSURLResponse *) response {
[webData setLength: 0];
}
-(void) connection:(NSURLConnection *) connection
didReceiveData:(NSData *) data {
[webData appendData:data];
}
-(void) connectionDidFinishLoading:(NSURLConnection *) connection {
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc]
initWithBytes: [webData mutableBytes]
length:[webData length]
encoding:NSUTF8StringEncoding];
//---shows the XML---
NSLog(theXML);
if( xmlParser )
{
}
xmlParser = [[NSXMLParser alloc] initWithData:webData];
[xmlParser setDelegate:self];
[xmlParser setShouldResolveExternalEntities:YES];
[xmlParser parse];
[HUD hide:YES];
}
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ( [elementName isEqualToString:@"retLocaResponse"] ) {
NSLog(@"Log Output%@",[attributeDict objectForKey:@"retLocaResult"]);
NSString *strValue= [attributeDict objectForKey:@"retLocaResult"];
if(strValue != (NSString*)[NSNull null])
{
[chunks addObject:[attributeDict objectForKey:@"retLocaResult"]];
}
else
{
}
recordResults = YES;
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:
(NSString *)namespaceURI qualifiedName:(NSString *)qName{
if ( [elementName isEqualToString:@"retLocaResponse"] ) {
NSLog(@"Log array%@",chunks);
[[self tableView]reloadData];
recordResults = NO;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [chunks count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"];
}
cell.textLabel.text =[chunks objectAtIndex:indexPath.row];
return cell;
}
但我没有将位置名称放入UITableView。我有什么不对，或者我该怎么做才能让这个工作。请帮帮我，以便完成我的申请。
Samkit Jain的编辑：与阵列的'init'崩溃。

服务器请求：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<retLoca xmlns="http://www.ctrlbase.nl/cbawebapp">
<tcUser>string</tcUser>
</retLoca>
</soap:Body>
</soap:Envelope>
服务器响应：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<retLocaResponse xmlns="http://www.ctrlbase.nl/cbawebapp">
<retLocaResult>string</retLocaResult>
</retLocaResponse>
</soap:Body>
</soap:Envelope>
答案 0 :(得分：3)
在viewDidLoad中初始化块
- (void)viewDidLoad
{
chunks = [[NSMutableArray alloc] init];
//same code here
}
如果这不起作用。 给我来自服务器的数据的完整日志以及来自xml的数据。
为Rick de Jong编辑： 从服务器获取数据存在一些问题。 如果您没有从服务器获取数据，则无法将数据保存在数组中。 因此，从服务器正确获取数据。 当数据从服务器正确传输时：
-(void) connectionDidFinishLoading:(NSURLConnection *) connection {
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc]
initWithBytes: [webData mutableBytes]
length:[webData length]
encoding:NSUTF8StringEncoding];
NSLog(@"Xml is :-----------%@",theXML); // This line should print your xml coming from from server
}
给我那个输出，之后我肯定会给你解决方案。
当您解析数据时，还有一件事。根据您的肥皂，您所需的数据不是作为xml的属性进入标签。所以你应该使用：
if ( [elementName isEqualToString:@"retLocaResult"] ) {
// code to save data and add to array
}
代码中的一个错误删除＆gt; 在以下代码中：
NSURL *url = [NSURL URLWithString:
@"http://www.ctrlbase.nl/cbawebapp/getLoca.asmx"];
最后我得到了输出：
使用此：
.h文件
{
NSMutableData *webData;
NSXMLParser *xmlParser;
NSMutableArray *chunks;
BOOL recordResults;
NSMutableString *strCaptured;
}
.m文件
