navToLogin() {
    this.refs.nav.replace({
        title: "Login",component: LoginScene,rightButtonTitle: "Sign Up",onRightButtonPress: this.navToRegister.bind(this)
    });
}

navToRegister() {
    this.refs.nav.replace({
        title: "Sign Up",component: RegisterScene,rightButtonTitle: "Login",onRightButtonPress: this.navToLogin.bind(this)
    });
}

render() {
    return (
        <NavigatorIOS
            ref = "nav"
            style={styles.navigator}
            initialRoute={{
                component: LoginScene,title: "Login",onRightButtonPress: this.navToRegister.bind(this)
            }}
        />
    );
}

虽然视图被正确更新,标题和rightButton在nav.replace()调用后不会更改.当我使用nav.push()一切都按预期工作.

我使用这个组件错了吗？
