     * 通过此方法可以使 Fragment 能够与外界做一些交互和通信, 比如说外部的 Activity 想让自己持有的某个 Fragment 对象执行一些方法,
     * 建议在有多个需要与外界交互的方法时, 统一传 {@link Message}, 通过 what 字段来区分不同的方法, 在 {@link #setData(Object)}
     * 方法中就可以 {@code switch} 做不同的操作, 这样就可以用统一的入口方法做多个不同的操作, 可以起到分发的作用
     * <p>
     * 调用此方法时请注意调用时 Fragment 的生命周期, 如果调用 {@link #setData(Object)} 方法时 {@link Fragment#onCreate(Bundle)} 还没执行
     * 但在 {@link #setData(Object)} 里却调用了 Presenter 的方法, 是会报空的, 因为 Dagger 注入是在 {@link Fragment#onCreate(Bundle)} 方法中执行的
     * 然后才创建的 Presenter, 如果要做一些初始化操作,可以不必让外部调用 {@link #setData(Object)}, 在 {@link #initData(Bundle)} 中初始化就可以了
     * <p>
     * Example usage:
     * <pre>
     * public void setData(@Nullable Object data) {
     *     if (data != null && data instanceof Message) {
     *         switch (((Message) data).what) {
     *             case 0:
     *                 loadData(((Message) data).arg1);
     *                 break;
     *             case 1:
     *                 refreshUI();
     *                 break;
     *             default:
     *                 //do something
     *                 break;
     *         }
     *     }

     *
     * // call setData(Object):
     * Message data = new Message();
     * data.what = 0;
     * data.arg1 = 1;
     * fragment.setData(data);
     * </pre>
