ios - 如何在 swift ios 中自动将光标从一个文本字段移动到另一个文本字段？

Question

    func textFieldDidBeginEditing(textField: UITextField) {
    scrlView.setContentOffset(CGPointMake(0, textField.frame.origin.y-70), animated: true)
}

func textFieldShouldReturn(textField: UITextField) -> Bool {


    textField.resignFirstResponder()

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

    return true
}

如何在第一个文本字段中输入值后自动将光标从一个文本字段移动到另一个文本字段？

Answer 1

首先，您需要按顺序向您的文本字段添加标签

func textFieldShouldReturn(textField: UITextField) -> Bool {

        let nextTag = textField.tag + 1;
        // Try to find next responder
        var nextResponderTxt: UITextField!
        nextResponderTxt = textField.superview?.viewWithTag(nextTag) as? UITextField
        if ((nextResponderTxt) != nil) {
            // Found next responder, so set it.
            nextResponderTxt.becomeFirstResponder()
        } else {
            // Not found, so remove keyboard.
            textField.resignFirstResponder()
        }
        return false; // We do not want UITextField to insert line-breaks.
    }

也可以把返回键改成next
