@IBOutlet var titleText: UITextField!
    @IBOutlet var contentText: UITextView!
    
    var noteTitle: String?
    var noteContent: String?

    override func viewDidLoad() {
        super.viewDidLoad()
        
        
        self.titleText.text = "这是标题"
        self.contentText.text = "这是内容
        
        //设置border宽度
        self.titleText.layer.borderWidth = 1
        //设置border的颜色
        self.titleText.layer.borderColor = UIColor.init(red: 229/255, green: 229/255, blue: 229/255, alpha: 1).CGColor
        //设置圆角
        self.titleText.layer.cornerRadius = 3
        
        self.contentText.layer.borderWidth=1
        self.contentText.layer.borderColor = UIColor.init(red: 229/255, green: 229/255, blue: 229/255, alpha: 1).CGColor
        self.contentText.layer.cornerRadius = 5
    }
