如何從NSURLConnection獲取會話ID？

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

NSURLConnection的使用代表獲得會話ID，如果您的請求得到反饋，會話ID：

-(void)connection:(NSURLConnection *)connection didReceiveResponse: 
    (NSURLResponse *)response 
{ 
    // Discard all previously received data. 
    [receivedData setLength:0]; 
} 

-(void)connection:(NSURLConnection *)connection didReceiveData: 
(NSData *)data 
{ 
    // Append the new data to the receivedData. 
[receivedData appendData:data];  
} 

-(void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    // Connection succeeded in downloading the request. 
    NSLog(@"Succeeded! Received %d bytes of data", [receivedData length]); 

    // Convert received data into string. 
    receivedString = [[NSString alloc] initWithData:receivedData 
     encoding:NSASCIIStringEncoding]; 
    //receivedString will have session id if request is appropriate 
    NSLog(@"From connectionDidFinishLoading: %@", receivedString); 

    // release the connection, and the data object 
    [conn release]; 
    [receivedData release]; 
} 

你要設定的協議NSURLConnectionDataDelegate，NSURLConnectionDelegate在.h文件中
