在AppDelegate中添加以下代码，以确保可以获取到用户信息：

// 接收本地通知
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    NSDictionary *userInfo = notification.userInfo;
    // 获取用户信息
}

// 启动选项
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (notification) {
        NSDictionary *userInfo = notification.userInfo;
        // 获取用户信息
    }
    return YES;
}
