我有一个数组:

var array = ["1|First", "2|Second", "3|Third"]

我如何切断"1 |","2 |","3 |"？
结果应如下所示:

println(newarray) //["First", "Second", "Third"]

我有两个 ViewController's.

1. FirstVC- 我有label和buttonsegue"莫代尔"

2. SecondVC- 我有(PickerView并button回到FirstVC):

   @IBAction func bntback(sender: AnyObject) {
             self.dissmissViewControllerAnimatied(true, completion: nil)
       }

我创建了代表SecondViewController:

protocol SendDataDelegate {
   func sendData(text:String)
}

下一个:

class SecondVC: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
      var delegate: SendDataDelegate!
      var firstvc = FirstVC()
      var arr = ["First", "Second", "Third"]
      @IBOutlet var pickview: UIPickerView!
      override func viewDidLoad() {
         super.viewDidLoad()
         pickview.dataSource = self
         pickview.selegate = self
     }

我的函数PickerView和函数我使用我的委托作为:

func pickerView (pickerView: UIPickerView, didSelectRow row: Int, …
