Where are an UIWebView's cookies stored?

Question

I'm building an iPhone app with cookies. Deleting cookies in the Safari settings doesn't delete them. Where are they stored? Is it possible to read them from another UIWebView?

Thanks!

Answer 1

Your application has its own "cookie jar" in the [NSHTTPCookieStorage sharedHTTPCookieStorage] container.

Here's how you might take a quick look at the cookies in your application's cookie jar:

NSHTTPCookie *cookie; NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage]; for (cookie in [cookieJar cookies]) {    NSLog(@"%@", cookie); } 

Several methods are available for filtering and manipulation. Take a look at the NSHTTPCookieStorage documentation for accessing cookies, and the NSHTTPCookie documentation for accessing individual cookie properties.

Thanks for the pointer Alex! To add to this I will drop in my "cookie dumper" that I created using Alex's example. Maybe this will help someone else.

- (void) dumpCookies:(NSString *)msgOrNil { NSMutableString *cookieDescs    = [[[NSMutableString alloc] init] autorelease]; NSHTTPCookie *cookie; NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage]; for (cookie in [cookieJar cookies]) {     [cookieDescs appendString:[self cookieDescription:cookie]]; } NSLog(@"------ [Cookie Dump: %@] ---------\n%@", msgOrNil, cookieDescs); NSLog(@"----------------------------------"); }  - (NSString *) cookieDescription:(NSHTTPCookie *)cookie {  NSMutableString *cDesc      = [[[NSMutableString alloc] init] autorelease]; [cDesc appendString:@"[NSHTTPCookie]\n"]; [cDesc appendFormat:@"  name            = %@\n",            [[cookie name] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [cDesc appendFormat:@"  value           = %@\n",            [[cookie value] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [cDesc appendFormat:@"  domain          = %@\n",            [cookie domain]]; [cDesc appendFormat:@"  path            = %@\n",            [cookie path]]; [cDesc appendFormat:@"  expiresDate     = %@\n",            [cookie expiresDate]]; [cDesc appendFormat:@"  sessionOnly     = %d\n",            [cookie isSessionOnly]]; [cDesc appendFormat:@"  secure          = %d\n",            [cookie isSecure]]; [cDesc appendFormat:@"  comment         = %@\n",            [cookie comment]]; [cDesc appendFormat:@"  commentURL      = %@\n",            [cookie commentURL]]; [cDesc appendFormat:@"  version         = %d\n",            [cookie version]];  //  [cDesc appendFormat:@"  portList        = %@\n",            [cookie portList]]; //  [cDesc appendFormat:@"  properties      = %@\n",            [cookie properties]];  return cDesc; }
