validation username and password from server database in iphone - iphone

hi friends i am doing here validation for username and password from server database
by given url of server i think i am going wrong i don't think my code is right
please some help me how to validation from server database for username and password in iphone
-(IBAction)buttonClick:(id)sender
{
NSString* username = nameInput.text;
NSString* pass = passInput.text;
if([nameInput.text isEqualToString:#"" ]&& [passInput.text isEqualToString:#""])
{
//greeting.text = #"Input Your Value";
//[nameInput resignFirstResponder];
//[passInput resignFirstResponder];
//return;
}
NSString *post =
[[NSString alloc] initWithFormat:#"uname=%# & pwd=%#",username,pass];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSURL *url = [NSURL URLWithString:#"http://server:85/VirtualTerminal/RecordAttendance.aspx"];//#"https://www.google.com/accounts/ServiceLogin?service=reader&passive=1209600&continue=http://www.google.co.in/reader/?hl%3Den%26tab%3Dwy&followup=http://www.google.co.in/reader/?hl%3Den%26tab%3Dwy&hl=en"]; //#"http://www.chakrainteractive.com/mob/iphone/login/chckusr.php"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:#"POST"];
[theRequest setValue:postLength forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPBody:postData];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if( theConnection )
{
webData = [[NSMutableData data] retain];
//test *t=[[test alloc]initWithNibName:#"test" bundle:nil];
//[self presentModalViewController:t animated:YES];
//[t release];
}
else
{
}
//}
[nameInput resignFirstResponder];
[passInput resignFirstResponder];
nameInput.text = nil;
passInput.text = nil;
k
[webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[connection release];
[webData release];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
NSLog(#"loginStatus");
greeting.text = loginStatus;
[loginStatus release];
[connection release];
[webData release];
}

Try setting with the following HTTPHeaderFields.
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"UTF-8" forHTTPHeaderField:#"charset"];
[request setValue:#"XMLHttpRequest" forHTTPHeaderField:#"X-Requested-With"];
I believe that the login call may be a "GET" method instead of "POST".
Once again confirm with the server URL that you make the call.
Thanks.

You can use this code:
-(IBAction)btnclick1:(id)sender
{
recordResult=FALSE;
greeting.text=#"Processing";
NSString *soapMessage=[NSString stringWithFormat:#" WEB SERVICE ",nameInput.text,passInput.text];
NSLog(#"%#",soapMessage);
NSURL *url=[NSURL URLWithString:#"http://SOME URL.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://tempuri.org/webservicename" forHTTPHeaderField:#"SOAPAction"];
[theRequest addValue:msgLength forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPMethod:#"POST"];
[theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection=[[NSURLConnection alloc]initWithRequest:theRequest delegate:self];
[myActivity startAnimating];
if(theConnection)
{
webData=[[NSMutableData data]retain];
}
else
{
NSLog(#"theConnection is NULL");
}
[nameInpt resignFirstResponder];
[passinpt resignFirstResponder];
}

}
that's it.

Hi I am writing iphone application that communicates web service, So I have two textfield, program need to read the value of first textfield and post the web service then after the response from web service it need to write second text field. But in the second textfield it doesnt write any thing. it prints null on console. Why it becomes?
Thanks.

It'll definately work.

NSXMLParser in model class gives me no result

When I debug my application and reach didEndElement, soapResult gives me nothing. On the contrary, when I use the same code in my controller class, I get the desired results, I wonder why.
You're not implementing parser:foundCharacters: I see that your allocating the string in start element but you would need to get the data out and set soapResults in foundCharacters. Where do you assign to soapResults? I don't see any code that ever assigns it which is why it's nil.
Also, didEndElement fires whenever the parser reaches the end of an element - not when it's done parsing. That would be parserDidEndDocument. So, it's possible that the parser hit the end of an element but still hasn't passed the two elements your interested in.

Web Services working on simulator, but not real device

I've just put my iOS app on my iPad, which is connected to my wireless network, and I cannot connect to web services. This was working in the simulator, however when I put it on the iPad, the connection times out. Is there something different needed when put on a real device?
Here is my code nevertheless:

The other thing I could think of is that the iPhone MUST be connected to a 3G network? So it can't access web services through a connection to a router?
192.168.51.3 look like a private subnet of a network, could it be that you WiFi is on another subnet?

iPhone: Object is null in another view when set with values read from XML

I am reading an XML from and parsing the data in one viewController class. When I try to access the object in another view, it appears as null. The NSMutableArray is set with values in the earlier view. I need these values to set a picker view. Could you please let me know where am I going wrong?

Problem with XML parsing on iPhone

When I receive data from web service my NSMutableData is filled with following XML:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><GetWeatherResponse xmlns="http://www.webserviceX.NET"><GetWeatherResult><?xml version="1.0" encoding="utf-16"?>
<CurrentWeather>
<Location>BERLIN MUNICIPAL AIRPORT, NH, United States (KBML) 44-35N 71-11W 345M</Location>
<Time>Oct 19, 2010 - 03:52 AM EDT / 2010.10.19 0752 UTC</Time>
<Wind> Calm:0</Wind>
<Visibility> 10 mile(s):0</Visibility>
<SkyConditions> clear</SkyConditions>
<Temperature> 23.0 F (-5.0 C)</Temperature>
<DewPoint> 21.0 F (-6.1 C)</DewPoint>
<RelativeHumidity> 91</RelativeHumidity>
<Pressure> 29.83 in. Hg (1010 hPa)</Pressure>
<Status>Success</Status>
</CurrentWeather></GetWeatherResult></GetWeatherResponse></soap:Body></soap:Envelope>
So when I search for "CurrentWeather" parser can't find it because of &qt, &lt etc. How to fix my NSMutableData to have normal values (<, > etc.)?

I've edited your question so it shows what I think is what you meant to paste. It looks like the web service is encapsulating a whole XML file as a string inside another XML tag. So what you need to do is get the entire content of the <GetWeatherResult> XML tag as a single string. I think NSXMLParser will automatically substitute the correct characters in place of > etc.
Having got that string, you need to pass it into another NSXMLParser to parse the content of it.
