I am new in ios. I am working in a application in which i need to post some data in nameValuepair so I used NSDictionary to crate a name value pair but with NSDictionary there is issue on server side to parse posted data. Is there any way to create NameValuePair in iOS 6 like in android there is a entity called BasicNameValuePair .
You can use this code,
NSURL *Url = [NSURL URLWithString:#"http://yourURLaddress"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:Url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
NSURLConnection *MyConnection= [[NSURLConnection alloc] initWithRequest:request
delegate:self];
[request setHTTPMethod:#"POST"];
NSString *postString = #"id=2315645&name=Ram&deviceId=3453564666643634";
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
[MyConnection start];

I am having a small Reddit API problem here. I am trying to follow the reddit api, as outlined here:
https://github.com/reddit/reddit/wiki/API
Logging in using a simple NSMutableURLRequest is not a problem:
NSString *user = [[NSString alloc]initWithString:[userFld text]];
NSString *passwd = [[NSString alloc]initWithString:[passwordFld text]];
NSString *urlString = [NSString stringWithFormat:#"http://www.reddit.com/api/login/username/?user=%#&passwd=%#",
[user stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
[passwd stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:#"POST"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
Which gives me a result from which I extract the user mod-hash:
4029916%2C2010-04-30T22%3A51%3A52%2C1243925043100000000000000000000000000000
Next I am trying to post, using:
NSString *redditUrlString = [NSString stringWithFormat:
#"http://www.reddit.com/api/submit/?uh=%#&kind=link&url=%#&sr=%#&title=%#&r=%#&api_type=json",
[appDelegate globalUhString],
#"www.google.com",
#"funny",
#"Google.com",
#"funny"];
NSURL *url = [NSURL URLWithString:redditUrlString];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:#"POST"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
However, when I extract the JSON response form the data received from this connection, I always receive the error below no matter what I use as the mod-hash:
[".error.USER_REQUIRED"]
Can someone explain what I have done incorrectly/how I can fix it?
It looks like you've not passing in the reddit_session cookie along with the uh parameter. The api documentation seems to explain the reason for receiving the error. According to this answer, it looks like you may need to issue the code:
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
in the applicationDidBecomeActive handler, as it may be rejecting the cookies due to the CookieAcceptPolicy being shared amongst all applications.
My Application requires a username and password fields.At the first login the validation working perfect.But the second time onwards there is no validation in the password field.It is automatically collected from the cache.
I am using the below codes for requesting.
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:xmlUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30.0];
[theRequest setHTTPMethod:#"GET"];
NSURLResponse* response = nil;
[NSURLConnection sendSynchronousRequest:theRequest
returningResponse:&response error:&error];
NSDictionary* dict=[theRequest allHTTPHeaderFields];
Thanks in advance
Just use this line instead:
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:xmlUrl]
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:30.0];
[theRequest setHTTPMethod:#"GET"];
I used NSURLConnection to communicate with Soap webservice and it worked fine.
Now I am using ASIFormDataRequest and I am not getting is it necessary to create soap message for that? and I am not aware what is SoapAction.
Here is the code I am using
NSURL *url = [NSURL URLWithString:#"http://SERVERNAME.com/WEBSERVICENAME"];
[self setFrmdataReq:[ASIFormDataRequest requestWithURL:url]];
[frmdataReq setRequestMethod:#"POST"];
[frmdataReq addRequestHeader:#"Content-Type" value:#"text/xml; charset=utf-8"];
[frmdataReq setPostValue:txtField.text forKey:#"city"];
[frmdataReq setDelegate:self];
[frmdataReq setDidFinishSelector:#selector(requestFinished:)];
[frmdataReq setDidFailSelector:#selector(requestFailed:)];
[frmdataReq startSynchronous];
UPDATE
Soap Message I used,
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSString *soapMessage = [NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"utf-8\"?>\
<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">\
<soap12:Body>\
<getCityTime xmlns=\"http://www.Nanonull.com/TimeService/\">\
<city>%#</city>\
</getCityTime>\
</soap12:Body>\
</soap12:Envelope>",txtField.text];
NSString *msgLength = [NSString stringWithFormat:#"%d",[soapMessage length]];
[request addValue:#"text/xml" forHTTPHeaderField:#"Content-Type"];
[request addValue:msgLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(conn)
{
responseData = [[NSMutableData data]retain];
NSLog(#"connection successful");
}
else
NSLog(#"connection fail.");
I didn't defined SOAPAction as I don't know anything about that.
When using ASIHTTPRequest, you need to create the SOAP request in basically the same way as you do with NSURLConnection.
The setPostValue call in ASIHTTPRequest is for create HTTP POST requests in the same format use for POST <form> tags in HTML.
For comparing ASIHTTPRequest / NSURLConnection, see things like:
ASIHTTPRequest vs NSURLConnection
and "What is ASIHTTPRequest?" on:

Any ideas?
Thanks in advance.
Did you try http://allseeing-i.com/ASIHTTPRequest/ ?
You can post any kind of datas. For example to send an image :
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"Ben" forKey:#"first_name"];
[request setPostValue:#"Copsey" forKey:#"last_name"];
[request setFile:#"/Users/ben/Desktop/ben.jpg" forKey:#"photo"];
(from http://allseeing-i.com/ASIHTTPRequest/How-to-use)
Good Luck ! :-)
