How to set http header for for HTTP in Objective-C?

I am trying to implement Http in IOS.

I use the following code to send GET command to the Server.

SERVER_IP        = @"xxx.xx.xxx.xxx";
PORT             = @"12345";
USER_ID             = @"1234-1234-1234-1234-1234";
USER_PWD             = @"123456";
url = [NSURL URLWithString:[NSString stringWithFormat:@"http://%@:%@/message/user/%@",SERVER_IP,PORT,USER_ID]];

[request setHTTPMethod:@"GET"];
    request = [NSURLRequest requestWithURL:url];

    NSDictionary *header = [request allHTTPHeaderFields];
    [header setValue:@"Authorization" forKey:USER_PWD];

    [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
        NSString *html = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        NSLog(@"%@",html);
    }];

It show **The resource requires authentication, which was not supplied with the request** at the log.

I have set the parameter header , but I don't know how to use it.

Can someone help me and teach me how to implement GET command and setting password?

Create an NSDictionary with all your header fields and use the following command to set the required headers.

NSDictionary *dictHeader = @{@"Content-Type": @"application/octet-stream", 
@"Authorization": @"accessToken"};

[request setAllHTTPHeaderFields:dictHeader];

You need to set the header on the NSURLRequest somehow, something like that will do.

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60];
[request setHTTPMethod:@"GET"];
[request setValue:USER_PWD forHTTPHeaderField:@"Authorization"];

Use the following: 

[request setValue:@"xxx" forHTTPHeaderField:@"Content-Type"];

But you have to change the NSURLRequest to NSMutableURLRequest, please check Zaph's answer

The header information is added to the URLRequest.

Create a NSMutableURLRequest and use the setValue:forHTTPHeaderField: method to add the header to the request.

There are many other setting available for NSMutableURLRequest.
