Can anyone tell me how to retrieve a HTTP header field
from a NSURLResponse?
Is the NSURLResponse actually a NSHTTPURLResponse (sublcass of
NSURLResponse)? If so, the allHeaderFields accessor method should get
what you need.
For example, in the connection:didReceiveResponse: delegate method of
NSURLConnection, if the connection is using the HTTP protocol, the
following would get the header field info:
- (void)connection:(NSURLConnection *)connection didReceiveResponse:
(NSURLResponse *)response
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
NSDictionary *httpResponseHeaderFields = [httpResponse
allHeaderFields];
NSLog(@"Connection did receive response: %@",
httpResponseHeaderFields);
}
(This most likely isn't how you'd actually want to implement the
connection:didReceiveResponse: method since the response might not be
an instance of NSHTTPURLResponse, etc.etc, but just trying to show
the concept.)
Also, the accessor methods for NSURLResponse (MIMEType,
expectedContentLength, suggestedFileName, etc.) might get what you need.
You're probably aware, but here's a link to good info on the URL
