在Deezer iOS SDK中恢复会话

我正在使用 Deezer iOS SDK,在Swift到目前为止一切顺利,除了会话,在Android SDK中存在一个方法.restoreSession()以避免弹出用户每次登录,但我在iOS SDK中看不到它,所以每次会话过期,用户弹出窗口再次使用hi的Deezer帐户登录,无论如何在iOS SDK中保存或恢复会话？

这是Android恢复会话代码：

// restore any saved session
SessionStore sessionStore = new SessionStore();
if (sessionStore.restore(deezerConnect,context)) {
    // The restored session is valid,navigate to the Home Activity
    Intent intent = new Intent(context,HomeActivity.class);
    startActivity(intent); 
}

是否可以在iOS SDK中执行此操作？

因为当用户使用Deezer SDK登录时,我没有收到代表的通知
