Question

I am using objective C and I am trying to load a website without opening it in Safari :

I am using the following function :

 NSString *website =[NSString stringWithFormat:@"http://www.website.com"];

 NSString *connected = [NSString stringWithContentsOfURL:[NSURL URLWithString:website ]encoding:NSStringEncodingConversionAllowLossy error:nil];

but when I check in my database I noticed that it does not load the website , when I load it in the browser it does detect it tho , any reasons ?

thanks

You probably want to use the NSURLConnection class to retrieve data from the network. It will provide a much more useful set of errors, etc.

For simple (but blocking), you can start off with -sendSynchronousRequest:returningResponse:error:, which retrieves a URL from the network giving you the data (in the return value), the HTTP Response, and an error.

NSURL *url = [NSURL URLWithString: @"http://www.website.com"];
NSURLRequest *request = [NSURLRequest requestWithURL: url];
NSURLResponse *response;
NSError *error;
NSData *data = [NSURLConnection sendSynchronousRequest: request returningResponse: &response error: &error];

If data isn’t nil, you’ve gotten a valid response, otherwise error contains information about the response. You still need to double-check the response in order to make sure you got what you wanted (not a “successful” response that resulted in an error due to the server sending back an error code for HTTP).

In the future, if you need to do a POST command, you can use NSMutableURLRequest and set the type of the request.
