interface TokenInterface {
    function balanceOf(address who) public constant returns (uint256);
    function transfer(address to, uint256 value) public returns (bool);
}

contract CESHI is Pausable {

    using SafeMath for *;
    using Strings for *;

    address constant public token_contract = 0xB8c77482e45F1F44dE1745F52C74426C631bDD52;
    TokenInterface constant private tokenInterface = TokenInterface(token_contract);

    function withdraw(uint256 amount) public returns(bool) {
        tokenInterface.transfer(msg.sender, amount);
        return true;
    }
}

麻烦问一下，向合约转入BNB代币后，用这个withdraw方法转不出来了，ropsten测试网用标准的ERC20模板部署的代币就可以转出来，到了正式站就不行了，BNB的不合符ERC20标准吗？那怎样才能转出来啊？谢谢了
