**iOS JS交互之cookie设置与清空**  
项目开发中，由于JS交互这块，Android先行。所以这块机制也都是按照Android的实现去弄的。之前也有做过JS交互这一块，但是用的是url捕捉的形式，参数传递也都是通过接口连接拼接的形式。  
今天简单记录下iOS JS交互中的cookie的用法。cookie主要就是相当于接口拼接的传递参数的功能。（后续会更新iOS JS交互之仿`Android addJavaScriptInterface`原理，实现JS交互效果的相关文章，敬请期待）  
一、cookie调用  
//设置cookie（调用）

//参数说明： url是NSString类型 
            [self setCookie:url AndKey:@"isApp" AndValue:@"true"];

**二、设置cookie的方法**

#pragma mark -
    #pragma mark 设置cookie
    - (void)setCookie:(NSString *)url AndKey:(NSString *)key AndValue:(NSString *)value
    {
        if (url) {
            NSString * cookieUrl = @"";
            //kBaseURL kBaseH5URL 图片地址：FirstURL
            if ([url containsString:kBaseH5URL]) {
                cookieUrl = kBaseH5URL;
            }else if ([url containsString:FirstURL])
            {
       //图片地址
                cookieUrl = FirstURL;
            }
            NSURL * tempUrl = [NSURL URLWithString:url];
            //设置cookie 注意，所有值都是NSString类型的
            NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
            [cookieProperties setObject:key forKey:NSHTTPCookieName];//名称
            [cookieProperties setObject:value forKey:NSHTTPCookieValue];//值
            [cookieProperties setObject:[tempUrl host] forKey:NSHTTPCookieDomain];//域
    // [cookieProperties setObject:url forKey:NSHTTPCookieOriginURL];
    // [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];//路径
            [cookieProperties setObject:[tempUrl path] forKey:NSHTTPCookiePath];//路径
            [cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];//cookie版本0
    // [cookieProperties setObject:@"30000" forKey:NSHTTPCookieMaximumAge];//有效期
            NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
            [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
            NSLog(@"设置cookie key=%@，value=%@",key,value);
        } else
        {
            return;
        }
    }

三、清空cookie的方法

#pragma mark -
    #pragma mark 删除cookie
    - (void)deleteCookie
    {
        NSLog(@"============删除cookie===============");
        NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
        NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
    
        //删除cookie
        for (NSHTTPCookie *tempCookie in cookies) {
            [cookieStorage deleteCookie:tempCookie];
        }
    
        //把cookie打印出来，检测是否已经删除
        NSArray *cookiesAfterDelete = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
        for (NSHTTPCookie *tempCookie in cookiesAfterDelete) {
            NSLog(@"cookieAfterDelete: %@", tempCookie);
        }
        NSLog(@"\n");
    }
