It will be something like this:

Code:

        NSURL* url = [NSURL URLWithString:@"http://www.renren.com/PLogin.do"];
	ASIHTTPRequest* request = [ASIFormDataRequest requestWithURL: url];
	[request setPostValue: @"user account email" forKey:@"email"];
	[request setPostValue: @"user account password" forKey:@"password"];
	[request setPostValue: @"http://www.renren.com/Home.do" forKey:@"origURL"];
	[request setPostValue: @"renren.com" forKey:@"domain"];

	[request setDelegate: self];
	[request startAsynchronous];

then in your delegate class(in my code I set it up to self) you have to implement some methods from ASIHTTPRequestDelegate protocol:

Code:

- (void)requestStarted:(ASIHTTPRequest *)request;
- (void)requestReceivedResponseHeaders:(ASIHTTPRequest *)request;
- (void)requestFinished:(ASIHTTPRequest *)request;
- (void)requestFailed:(ASIHTTPRequest *)request;

- (void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data;

- (void)authenticationNeededForRequest:(ASIHTTPRequest *)request;
- (void)proxyAuthenticationNeededForRequest:(ASIHTTPRequest *)request;

I have same question on this too, but i couldnt get it to submit the form

Code:

<form name="form2" method="post" action="/webtix/welcome/welcome.do">

<input type="text" name="cardNum" id="serial" size="25" maxlength="24"/></td>
<input name="pass" type="password" id="passwd" size="25" maxlength="24"/></td>
<input class="go_btn" type="submit" value="Login" id="gobtn2" onclick="return validate(this.form);" />

</form>

Code:

NSURL* url = [NSURL URLWithString:@".../webtix/welcome/welcome.do"];
ASIFormDataRequest* request = [ASIFormDataRequest requestWithURL: url];
[request setPostValue:@"01234" forKey:@"cardNum"];
[request setPostValue:@"01234" forKey:@"pass"];
[request setDelegate: self];
[request startAsynchronous];

I still cant get data from login page...can anyone tell me what is wrong with my code?
