分段控制器问题
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。
