How to put SOAP response into UITableView? - ios

Question

I use SOAP webservices in my app. I make an request with the following statements (.m file):
- (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;
}
But I don't get the Location names into an UITableView. What do I wrong or what can I do to let this work. Please help me so I can finish my application.
Thanks a lot!
EDIT for Samkit Jain: Crashes with the 'init' for the array.

Answer 1

Initialize chunks in viewDidLoad
- (void)viewDidLoad
{
chunks = [[NSMutableArray alloc] init];
//same code here
}
If this does not work.
Give me the complete log of your data coming from server and data from xml also.
Edit for Rick de Jong:
There is some problem in your getting data from server.
If you are not getting data from server, data can't be saved in array.
So, get your data properly from server.
When data will come properly from server :
-(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
}
Give me that output, I will surely give you solution after that.
One more thing, when you are parsing data. your required data is coming in tags not as attribute of xml, as per your Soap. So you should use :
if ( [elementName isEqualToString:#"retLocaResult"] ) {
// code to save data and add to array
}
in didStartElement and didEndElement to get proper result.
One more error in your code remove >
in following code :
NSURL *url = [NSURL URLWithString:
#"http://www.ctrlbase.nl/cbawebapp/getLoca.asmx"];
Finally I got the output :
Use this :
.h file
{
NSMutableData *webData;
NSXMLParser *xmlParser;
NSMutableArray *chunks;
BOOL recordResults;
NSMutableString *strCaptured;
}
.m file
- (void)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>"];
