在textView中顯示數組元素（Swift）

Question

如何將數組中的所有元素添加到1秒延遲的textView中？

語種迅速 （還是比較新的編程）

Answer 1

我認爲這是你需要

class ViewController: UIViewController { 

    @IBOutlet weak var textView: UITextView! 

    var array = ["string1", "string2", "string3"] 
    var i = 0 
    var str: String = "" 
    var timer = NSTimer() 

    func testFunc() { 
     str += "\(array[i])\n" 
     textView.text = str 
     if i == count(array) - 1 { 
      timer.invalidate() 
     } 
     i += 1 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: Selector("testFunc"), userInfo: nil, repeats: true) 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 
}
