ios - 两个不同的按钮对同一 View Controller 执行 segue，但希望通过一个按钮禁用 segue 的用户交互

Question

我正在从同一屏幕上的两个不同按钮对同一 View Controller 执行 segue，因此使用相同的 segue 标识符。假设按钮是 B1 和 B2。因此，当我从 B1 的 segue 执行 segue 时，我希望目标 View Controller 禁用用户交互，但是当我从 B2 的 segue 执行时，我希望目标 View Controller 可单击且其文本字段可编辑。请帮我实现它。这里...考虑将 B2 部分按下，将 B1 视为 toplbl，请帮助我使用此代码实现它，以便建议我可以在此处进行更改。

@IBAction func partialPressed(sender: UIButton)
{
    let i = self.getIndex(sender.tag)
    let j = self.getSection(sender.tag)
    let indexarr = ["index":i, "section":j]

    if getSection(sender.tag) == 0
    {

    let arr = getArray(sender.tag)
    performSegueWithIdentifier("partialSupplement", sender: arr)

    }
    else if getSection(sender.tag) == 1
    {
        let arr = getArray(sender.tag)
        performSegueWithIdentifier("PartialPopup", sender: arr)




    }

    else if getSection(sender.tag) == 2
    {
        let arr = getArray(sender.tag)
        performSegueWithIdentifier("FoodLifestyle", sender: arr)



    else if getSection(sender.tag) == 3
    {
        let arr = getArray(sender.tag)
        performSegueWithIdentifier("Food", sender: arr)


    else if getSection(sender.tag) == 4
    {
        let arr = getArray(sender.tag)
        performSegueWithIdentifier("Others", sender: arr)
      task.resume()
    }

}

使用prepareForSegue:方法。 iOS 会将按钮作为 sender 参数传递给您，并使目标 View Controller 作为 UIStoryboardSegue 参数的一部分可用。

检查sender，看它是B1还是B2。当发送者为 B2 时，在 segue 的目标 Controller 中禁用用户交互:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: Any?) {
    if segue.identifier == "MySegue" {
        let enableInteration = (sender != button2)
        segue.destinationViewController.view.userInteractionEnabled = enableInteration
    }
}
