把汉字放进url，例如 * http://lolbox.duowan.com/phone/apiCheckUser.php?action=getPlayersInfo&serverName=电信十四&target=蛋壳儿 *
但是直接这样请求的话，提示url是不符合要求的，无法获得数据。这就需要把url转化为utf8编码的格式

方法一：
//预留参数的网址
NSString *baseUrlString = @"http://lolbox.duowan.com/phone/apiCheckUser.php?action=getPlayersInfo&serverName=%@&target=%@";
NSString *paramServer = @"电信十四";
NSString *paramName = @"蛋壳儿";
//合成新的网址
NSString *urlString = [NSString stringWithFormat:baseUrlString,paramServer,paramName];
//将网址转化为UTF8编码
NSString *urlStringUTF8 = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

方法二 ：
 NSString *urlstr = [NSString stringWithFormat:@"%@login/goView?title=电信中心",BaseUrl];
  
 webVC.loadUrl = [urlstr stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
