标题: objective-c - 如何在 iOS 应用程序中从 NSURLRequest 修改 cookie

您好，我需要修改一个 cookie，但我正在 iOS 中开发，有人知道如何更改它。也许在 UIWebViewDelegate 中带有 webView:shouldStartLoadWithRequest:navigationType:??

Best Answer-推荐答案

由于IOS不支持WebKit.framework，最好的方法是使用UIWebView shouldStartLoadWithRequest和webViewDidFinishLoad的事件，我使用NSHTTPCookieStorage类作为cookie，并修改如下

NSHTTPCookieStorage *sharedHTTPCookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray *cookies = [sharedHTTPCookieStorage cookiesForURL:[NSURL URLWithString:self.webView.request.URL.absoluteString]];
NSEnumerator *enumerator = [cookies objectEnumerator];
NSHTTPCookie *cookie;
while (cookie = [enumerator nextObject])
{
    if ([[cookie name] isEqualToString:key]) 
    {
        NSString *actcookie = [cookie value];
        NSMutableString *newcookiestring = [NSMutableString stringWithFormat"%@changes",actcookie];
        NSMutableDictionary *propscook = [[NSMutableDictionary alloc] initWithDictionary: [cookie properties]];
        [propscook setObject:newcookiestring forKey:NSHTTPCookieValue];
        NSHTTPCookie *newcookie = [NSHTTPCookie cookieWithProperties:propscook];

        [sharedHTTPCookieStorage setCookie:newcookie];

        return [cookie value];
    }
}
return nil;
