如何重新加载选择器视图？

Question

@IBAction func nextTurn(sender: AnyObject) {
    if numberOfTurn < (playersForPicker.count-1) {
    numberOfTurn++
    }else{
        numberOfTurn = 0
    }
    titleForTwo.title = playersForPicker[numberOfTurn]
    var lostPlayer = playersForPicker[numberOfTurn]

    titleForTwo.title = playersForPicker[numberOfTurn]

    playersForPicker.removeAtIndex(numberOfTurn)

    playerPicker.reloadAllComponents()

         playersForPicker.insert(lostPlayer, atIndex: numberOfTurn)
    startButton.setTitle("Next Turn", forState: UIControlState())
}

The playerPicker doesn't reload or change, So i need help on how to refresh or reload a picker view when clicking a button.

Answer 1

Why should it change? You are removing playersForPicker[numberOfTurn], but you set lostPlayer to that same value, then add it back to the same place in the array. The array hasn't changed, so neither will your picker. You are properly reloading your picker view. If you comment out the line where you insert lostPlayer, you should see that item disappear from the picker.
