详解iOS App开发中Cookie的管理方法

+ (NSDictionary<NSString *, NSString *> *)requestHeaderFieldsWithCookies:(NSArray<NSHTTPCookie *> *)cookies;
//从指定的响应头和URL地址中解析出Cookie数据
+ (NSArray<NSHTTPCookie *> *)cookiesWithResponseHeaderFields:(NSDictionary<NSString *, NSString *> *)headerFields forURL:(NSURL *)URL;
//Cookie数据中的属性字典
@property (nullable, readonly, copy) NSDictionary<NSString *, id> *properties;
//请求响应的版本
@property (readonly) NSUInteger version;
//请求相应的名称
@property (readonly, copy) NSString *name;
//请求相应的值
@property (readonly, copy) NSString *value;
//过期时间
@property (nullable, readonly, copy) NSDate *expiresDate;
//请求的域名
@property (readonly, copy) NSString *domain;
//请求的路径
@property (readonly, copy) NSString *path;
//是否是安全传输
@property (readonly, getter=isSecure) BOOL secure;
//是否只发送HTTP的服务
@property (readonly, getter=isHTTPOnly) BOOL HTTPOnly;
//响应的文档
@property (nullable, readonly, copy) NSString *comment;
//相应的文档URL
@property (nullable, readonly, copy) NSURL *commentURL;
//服务端口列表
@property (nullable, readonly, copy) NSArray<NSNumber *> *portList;

三、清除Cookie
清除所有的cookie 方法：

NSURL *url = [NSURL URLWithString:@"http://www.easck.com/>     if (url) { 
        NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:url]; 
        for (int i = 0; i < [cookies count]; i++) { 
            NSHTTPCookie *cookie = (NSHTTPCookie *)[cookies objectAtIndex:i]; 
            [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie]; 
             
        }  
  清除某一个特定的cookie方法：
NSArray * cookArray = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:self.loadURL]]; NSString * successCode = @""; for (NSHTTPCookie*cookie in cookArray) { if ([cookie.name isEqualToString:@"cookiename"]) { [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie]; } } 

清除某一个url缓存的方法：
[[NSURLCache sharedURLCache] removeCachedResponseForRequest:[NSURLRequest requestWithURL:url]]; 

清除所有缓存方法：       
[[NSURLCache sharedURLCache] removeAllCachedResponses];
