ios - 使用 XLPagerTabStrip 在 child 之间传递数据

Question

我正在使用 https://github.com/xmartlabs/XLPagerTabStrip我有 3 个 child ...我想将值(value)从 child 传递给 child ..

我能够像这样将值从 parent 传递给第一个 child :

    let parentVC = self.parent as! ParentViewController
    mobile = parentVC.mobile

但现在我想将它从 child 1 传递给 child 2 .. 尝试了上面的方法，但我得到了 mobile is nil

父 View 中的 mobile 声明如下:

    var mobile = ""

如何在 child 之间传递数据？

       override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
    let child1 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "cominfo")
    let child2 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "comedu")
    let child3 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "comcv")        
    return [child1,child2,child3]
}

override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
    let child1 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "cominfo") as! yourChildClassname
    child1.mobile = self.mobile
    let child2 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "comedu")as! yourChildClassname
    child2.mobile = self.mobile
    let child3 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "comcv")  as! yourChildClassname
    child3.mobile = self.mobile       
return [child1,child2,child3]
 }
