分段控制器问题

Question

我上面的段控制器连接到下面的代码。

@IBOutlet weak var coatSegmentController: UISegmentedControl!

@IBAction func coatSelectInput() {

        switch (self.unitSegmentController.selectedSegmentIndex) {

        case 0:
            coatSetter = 1
            //println("SWITCHED TO coat 1")
            println(unitSegmentController.selectedSegmentIndex)

        case 1:
            coatSetter = 2
            //println("SWITCHED TO coat 2")
            println(unitSegmentController.selectedSegmentIndex)

        case 2:
            coatSetter = 3
            //println("SWITCHED TO coat 3")
            println(unitSegmentController.selectedSegmentIndex)

        default:
            println("Coat switch did not work")

        }


    }

无论我选择哪个片段，它总是返回我选择的第一个片段。

如果我将它挂在我的单位分段插座上，它就能正常工作。但随后单位停止工作。

@IBOutlet weak var unitSegmentController: UISegmentedControl!

知道那是什么意思吗？我已经尝试了一切。多次删除并重新创建。似乎没什么用。

以下是该视图的完整代码。
