ios - 如何在 iOS 的 UIWebview 中删除特定的 cookie

Question

我正在创建一个 UIWebview。在 UIWebview 中，我必须删除一些 cookie。如何找出cookie文件名？

-(void)saveHTTPCookies {

NSMutableArray *cookieArray = [[NSMutableArray alloc] init];

NSArray *currentCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];

for (NSHTTPCookie *cookie in currentCookies) {  

[cookieArray addObject:cookie.name];

NSMutableDictionary *props = [NSMutableDictionary dictionary];

[props setObject:cookie.name forKey:NSHTTPCookieName];    

[props setObject:cookie.value forKey:NSHTTPCookieValue];   

[props setObject:cookie.domain forKey:NSHTTPCookieDomain];    

[props setObject:cookie.path forKey:NSHTTPCookiePath];    

[props setObject:[NSNumber numberWithUnsignedInteger:cookie.version] forKey:NSHTTPCookieVersion];     

[props setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

[userDefaults setValue:props forKey:cookie.name];    

[userDefaults synchronize];

}

[userDefaults setValue:cookieArray forKey:@"cookieArray"];

[userDefaults synchronize];

}

感谢任何帮助

如果您知道自定义 cookie 的 url，以下可能对您有所帮助...

NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray *cookies= [cookieStorage cookiesForURL:
                                [NSURL URLWithString:@"http://www.sample.com"]];  
for (NSHTTPCookie *cookie in cookies) {
        [cookieStorage deleteCookie:cookie];
}
