checkFirebaseAuth(accessTokenData).then((user) => {
          
          if (user){
            Actions.home({type: ActionConst.RESET})

          }else{ // user needs to login to get a Facebook auth token
            Actions.login({type: ActionConst.RESET})
          }
        })
      })

                  { text: "退出", onPress: () => { axios.get(LOUGOUT_URL).then(() => Actions.login()); } },
                  { text: "取消", onPress: () => console.log("Cancel Pressed"), style: "cancel" },

return (dispatch, state) => {
      if (WebIM.conn.isOpened()) {
        WebIM.conn.close('logout')
      }

      NavigationActions.login();
    }
  },

loginScreen = () => {
        Actions.login();
    }
    signUpScreen = () => {

        <button title="Go to Login"> Actions.login({ data: 'Custom data', title: 'Custom title' })} /&gt;
        </button><button title="Go to Register page"></button>

            onPress={()=>Actions.login()}
            buttonText='Login'

      .catch(() => Actions.login());
  };

                            ? () => Actions.login()
                            : provider == 'google'

      .then(() => setTimeout(() => { Actions.pop(); Actions.login(); }, 1000))
      .catch(() => {});

processAuth(props) {
    if(props.auth.user != null) {
      if(props.auth.user.uid) {
        Actions.main({ type: 'reset' });
      }else{
        Actions.login({ type: 'reset' });
      }
