iPhone URL encoding Problem

Question

Hello stackoverflow,

Have a slight problem. Trying to post XML to a server. To do this, I have to encode the XML string in URL format.

NSString *encodedString = [NSString stringWithFormat:@"xmlValue=%@",[post stringByAddingPercentEscapesUsingEncoding: NSASCIIStringEncoding]];

That's what I have and it works for all the characters EXCEPT the '='. This does not get converted to %3D. Has anyone else ever had this problem before? Am I specifying the wrong encoding type? I have tried "NSUTF8StringEncoding" as well.

This is a little piece of the XML string:

@"<xml-service application=\"broadcast\" type=\"REQUEST\"><identity token=\"xxxxxxxx\".....

Any help would be appreciated! Thanks
