如何在iOS应用程序中修改来自NSURLRequest的cookie

Question

嗨我需要修改一个cookie，但我在iOS中开发，有人知道如何更改它。也许在使用webView的UIWebViewDelegate中：shouldStartLoadWithRequest：navigationType：??

因为WebKit.framework不适用于IOS，最好的办法是使用事件的UIWebView shouldStartLoadWithRequest和webViewDidFinishLoad，还有我用NSHTTPCookieStorage类的Cookie，并有修改如下

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;
