Question

I am trying to make a url by first collecting the parameters, and then in one statement creating the actual url. Here is what I am trying to do:

NSString *urlString = @"http://www.some_login_url.com?email=%@&password=%@";

NSString *email = self.email.text;
NSString *password = self.password.text;

NSString *url_to_send = [NSString stringWithFormat:@"%@%@", urlString , email , password];     

So what I wanted to do was replace the @ symbols with the values in the variables, but instead the second variable just got appended to the end of the string.

How would I change the last line so I could put the right parameters in their correct spots?

Thanks!!

I think you meant:

NSString *url_to_send = [NSString stringWithFormat:urlString , email , password];     

But you might want to look for ways to construct a URL that do proper escaping of arguments, etc. For example, see this question.
