Problem with NSString and NSMutableURLRequest

Question

I am having issues with adding a header to NSMutableURlRequest, the problem is that when I add the header below "Authorization" it does not show up. However if I replace my instance variable "auth" below with a static string exp (@"asdadsadsadga") it the "Authorization" header will show up. I am pretty lost at this point.

NSURL *url = [NSURL URLWithString:@"https://www.google.com/analytics/feeds/accounts/default"];
NSMutableURLRequest *profileRequest = [NSMutableURLRequest requestWithURL:url];

NSLog(auth); //prints correctly
NSString *authString = [NSString stringWithFormat:@"GoogleLogin Auth=%@", auth];
[profileRequest addValue:authString forHTTPHeaderField:@"Authorization"];

NSDictionary *allheaders = [profileRequest allHTTPHeaderFields];

for (id key in allheaders)
{
  //Nothing prints
  NSLog(@"key: %@, value: %@", key, [allheaders objectForKey:key]);
}

NSLog(auth); //Prints correctly

Answer 1

First, swap out NSLog(auth) with NSLog(@"%@", auth). The former is dangerous, and may expose some of what's going on here. You should also try adding early on:

auth = @"asdasdasdad";

You should also try just dumping allheaders directly:

NSLog(@"%@", [profileRequest allHTTPHeaderFields];

This may shed some light. I suspect that the problem is in your auth variable, possibly related to memory management, not in NSMutableURLRequest.

The code you are using to generate your base64Encoded string is broken.

Try using the method outlined at the bottom of the page: http://cocoawithlove.com/2009/06/base64-encoding-options-on-mac-and.html
