Segue 不会执行 Swift [英] Segue won't execute Swift

问题描述

我有一个从集合视图(封装在视图控制器中)到另一个视图控制器的 segue 运行，但该函数从未被调用:

I have a segue running form a Collection View (wrapped in a view controller) in to a another view controller, how ever the function never gets called:

  func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
  println(segue.identifier)
  println(sender)
  println("SEGUE SELECTED:  \(segue.identifier)")

  if(segue.identifier == "segueToDetailView") {
    let cell = sender as CollectionViewCell;
  }
}

在函数开始处放置了一个断点，但从未到达.

Have placed a breakpoint at start of function but never reached.

感谢任何输入.

推荐答案

我建议不要从单元格或任何对象(如按钮)创建 segue(s).创建从一个 ViewController 到具有唯一标识符的 OtherViewController 的 segue.然后使用标识符自己调用 performSegueWithIdentifier.

I will suggest not to create segue(s) from cell or any object(like button). Create segue from one ViewController to OtherViewController with unique identifier. And then call the performSegueWithIdentifier yourself using the identifier.
