Question

I have user authentication in my iPhone application. User login works in a way that application send username/password to web service for user check. The problem I have now is I don’t know how to setup ‘timeout’ (30 seconds) and stop requesting data from web service?

NSString *soapMsg = 
    [NSString stringWithFormat:
     @"<?xml version=\"1.0\" encoding=\"utf-8\"?>...", username, password
     ];

    NSURL *url = [NSURL URLWithString: @"http://...Service.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://.../LoginUser" forHTTPHeaderField:@"SOAPAction"];    
    [req addValue:msgLength forHTTPHeaderField:@"Content-Length"];   
    [req setHTTPMethod:@"POST"];
    [req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];

    conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];

    if (conn) 
    {
        webData = [[NSMutableData data] retain];
    }    

Answer 1

[req setTimeoutInterval:urInterval];

setTimeoutInterval:

Sets the receiver’s timeout interval, in seconds.

- (void)setTimeoutInterval:(NSTimeInterval)timeoutInterval

Parameters

timeoutInterval

The timeout interval, in seconds. If during a connection attempt

the request remains idle for longer than the timeout interval, the
request is considered to have timed out. The default timeout interval
is 60 seconds.
