在使用UIWebView加載網(wǎng)頁時，有時會需要傳Cookie

實現(xiàn)代碼如下：

 [self setCookie];//設(shè)置cookie

在此之前，設(shè)置或者刪除cookie。

 NSURL *url = [NSURL URLWithString:_urlstr];   
 NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:60];  
 [self.myWeb loadRequest:request];  

//////////////////////////////////////////////////////
//設(shè)置cookie
- (void)setCookie{
NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
[cookieProperties setObject:@"cookie_user" forKey:NSHTTPCookieName];
[cookieProperties setObject:uid forKey:NSHTTPCookieValue];
[cookieProperties setObject:@"xxx.xxx.com" forKey:NSHTTPCookieDomain];
[cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
[cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];
[cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

NSHTTPCookie *cookieuser = [NSHTTPCookie cookieProperties];  
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookieuser];  
}  

NSHTTPCookieStorage實現(xiàn)管理共享的cookie存儲一個singleton對象（共享實例）。 這些cookies是所有的應用程序之間的共享和跨進程同步保存

//清除cookie
- (void)deleteCookie{
NSHTTPCookie *cookie;

    NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];  
  
    NSArray *cookieAry = [cookieJar cookiesForURL: [NSURL URLWithString: _urlstr]];  
  
    for (cookie in cookieAry) {  
      
        [cookieJar deleteCookie: cookie];  
      
    }  
}
