swift - 当我前进或后退到下一页时，如何删除我从 navigationController 创建的 uiview？

Question

我以编程方式创建了一个 View ，并将其作为 subview 添加到 navigationController 中。我现在面临的问题是，当我前进到下一页或上一页时， View 不会被删除。可以做什么来删除 View 或仅将 View 包含在导航 Controller 的特定 View Controller 中？

  self.footerView = UIView(frame: CGRectMake(0, UIScreen.mainScreen().bounds.height - 40, tableView.frame.size.width, 40))
        self.footerView.tag == 1
        footerView.backgroundColor = themeColor
        let totalLabel = UILabel(frame: CGRectMake(16, 8, footerView.frame.width/2, 30))
        totalLabel.text = "Rs. 200"
        totalLabel.textColor = UIColor.whiteColor()
        let button = UIButton(type:UIButtonType.Custom)

        button.frame =  CGRectMake(footerView.frame.width/2 - 16, 8, footerView.frame.width/2, 30)
        button.layer.masksToBounds = true
        button.setTitle("Save and Continue", forState: .Normal)
        button.setTitleColor(UIColor.whiteColor(), forState: .Normal)
        button.addTarget(self, action: "saveButonPressed:", forControlEvents: .TouchUpInside)
        button.layer.borderColor = UIColor.whiteColor().CGColor
        button.layer.borderWidth = 2
        button.layer.cornerRadius = 8
        footerView.addSubview(totalLabel)
        footerView.addSubview(button)
        self.navigationController?.view.addSubview(footerView)

在ViewController中创建相同的View。

let customView = //your view creation code.
self.view.addSubview(customView);
//this will add view to your viewcontroller's view, not in navigationContoller.

您可以删除 View ，

customView.removeFromSuperview()
