在UIWebView中设置cookie

项目中，需要在打开3g网页时，通过cookie传递一些信息。

实现代码如下：

在

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

之前，设置或者删除cookie。
