遍历添加多个cookie 后台收到的cookie是都好隔开的，用他们的方法获取不到我这边设置的cookie，于是尝试自己拼接分号，后台可以拿到
_urlString= [_urlString dm_UTF8String];
NSURL *url = [NSURL URLWithString:_urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPShouldHandleCookies = YES;
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
DMLog(@"==cookies=====%@",cookies);
NSMutableArray *cookieStrs = [NSMutableArray array];
for(NSHTTPCookie*coincookies) {
NSString*cookieStr = [NSStringstringWithFormat:@"%@=%@",co.name,co.value];
[cookieStrsaddObject:cookieStr];
}
NSString*cookieStr = [cookieStrscomponentsJoinedByString:@";"];
[requestaddValue:cookieStrforHTTPHeaderField:@"Cookie"];
[self.webView loadRequest:request];
