封装的工具类:

+(NSHTTPCookie*)cookieMakerWithName:(NSString*)name value:(NSString*)value Domain:(NSString*)domain path:(NSString*)path{
    if ([name isEqualToString:EMPTYSTRING] || [value isEqualToString:EMPTYSTRING]) {
        return nil;
    }
    NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
    [cookieProperties setObject:name forKey:NSHTTPCookieName];
    [cookieProperties setObject:value forKey:NSHTTPCookieValue];
    [cookieProperties setObject:domain forKey:NSHTTPCookieDomain];
    [cookieProperties setObject:domain forKey:NSHTTPCookieOriginURL];
    [cookieProperties setObject:path forKey:NSHTTPCookiePath];
    [cookieProperties setObject:@"1" forKey:NSHTTPCookieVersion];
    NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
    return cookie;
}

+(NSArray*)cookieMakerWithValueDic:(NSDictionary*)valueDic Domain:(NSString*)domain path:(NSString*)path{
    if ([valueDic isEqual:@{}]) {
        return nil;
    }
    NSMutableArray *cookieArray = [NSMutableArray array];
    for (NSString* key in valueDic) {
        NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
        [cookieProperties setObject:key forKey:NSHTTPCookieName];
        [cookieProperties setObject:[valueDic objectForKey:key] forKey:NSHTTPCookieValue];
        [cookieProperties setObject:domain forKey:NSHTTPCookieDomain];
        [cookieProperties setObject:domain forKey:NSHTTPCookieOriginURL];
        [cookieProperties setObject:path forKey:NSHTTPCookiePath];
        [cookieProperties setObject:@"1" forKey:NSHTTPCookieVersion];
        NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
        [cookieArray addObject:cookie];
    }
    
    return cookieArray;
}

工具的调用:

#pragma mark - setCookie
- (void)setCookie {
    
    NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSDictionary *cookieValueDic = [NSDictionary dictionaryWithObjectsAndKeys:
                                    @"value1",@"key1",
                                    @"value2",@"key2",
                                    @"value3",@"key3",
                                    nil];
    NSArray *cookieArray = [VATool cookieMakerWithValueDic:cookieValueDic Domain:self.urlHost path:@"/"];
    for (NSHTTPCookie *cookie in cookieArray) {
        [cookieStorage setCookie:cookie];
    }
    
    [self.webView reload];
}
