UIWebView的cookie存储在哪里？

Question

我正在构建一个带有cookie的iPhone应用程序.在Safari设置中删除Cookie不会删除它们.它们存放在哪里？是否可以从另一个UIWebView读取它们？

谢谢!

Answer 1

您的应用程序在[NSHTTPCookieStorage sharedHTTPCookieStorage]容器中有自己的"cookie jar" .

以下是您可以快速查看应用程序cookie jar中的cookie的方法:

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

有几种方法可用于过滤和操作.看看在NSHTTPCookieStorage文档访问饼干和NSHTTPCookie访问各个Cookie属性的文件.

感谢Alex指针!为了补充这一点,我将放入我使用Alex的示例创建的"cookie dumper".也许这会帮助别人.

- (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;
}
