Question

I am calling a login script on the server using http call from iphone.
the script returns a string “Invalid” or “valid” based on given username/pswd.

Here is what I am using:

NSString *myurlstr = [[NSString alloc] initWithFormat:@”http://www.mysite.com/iph/login.aspx?username=%@&password=%@“,uname,pswd];
NSString *resultstr = [NSString stringWithContentsOfURL:[NSURL URLWithString:myurlstr] encoding:NSUTF8StringEncoding error:&error];

NSLog(@”HERE IS THE ONE: %@”,resultstr);

Here is what the Console log prints:

TestingTrying[51514:207] HERE IS THE ONE: Invalid Login/Password

Can someone help on how to get the string only(Invalid Login/Password) and not the content that starts from DOCTYPE onwards?

Answer 1

If your simply asking how to get the first line from your server response, use a tokenizer. This should point you in the right direction, just use new line which is /n from memory as the delimiter.
