ios - 如何使用点击手势放置文本字段位置

Question

super.viewDidLoad()

    let tapGesture = UITapGestureRecognizer(target: self, action: Selector("hideKeyboard"))
    tapGesture.cancelsTouchesInView = true

    scrlView.addGestureRecognizer(tapGesture)

    //self.navigationController!.navigationBarHidden = true

     scrlView.contentSize = CGSizeMake(UIScreen .mainScreen().bounds.size.width, (regButton.frame.size.height + regButton.frame.origin.y)+20)

    // Do any additional setup after loading the view.
}

func hideKeyboard() {
    scrlView.endEditing(true)
    scrlView .setContentOffset(CGPointMake(0, 0), animated: true)
}


@IBAction func tapped(sender: AnyObject) {

    scrlView.endEditing(true)
    scrlView .setContentOffset(CGPointMake(0, 0), animated: true)
}

我的隐藏键盘功能没问题。但现在我想在点击键盘上方的文本字段时更改它们的位置。

Answer 1

试试这个:

func textFieldShouldBeginEditing(textField: UITextField) -> Bool{
    scrl.setContentOffset(CGPointMake(0.0, textField.center.y-120), animated: true)
}

并且您的 func hideKeyboard() 应保持不变 希望对你有所帮助
