我们如何让键盘出现在swift中的textView下面？

Question

我用键盘出现在textfield下面

在View上加载添加观察者()

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(Gold_Loan_First_ViewController.keyboardDidShow(_:)), name: UIKeyboardDidShowNotification, object: nil)

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(Gold_Loan_First_ViewController.keyboardWillBeHidden(_:)), name: UIKeyboardWillHideNotification, object: nil)

然后更新框架

weak var activeField: UITextField?

func textFieldDidEndEditing(textField: UITextField) {
    self.activeField = nil


}
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
    if textField==txtOTP {
        txtOTP.errorMessage=""
    }
  return true
}
func textFieldDidBeginEditing(textField: UITextField) {
    self.activeField = textField

}




func keyboardDidShow(notification: NSNotification)
{
    if let activeField = self.activeField,
        let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
        let contentInsets = UIEdgeInsets(top: 0.0, left: 0.0, bottom: keyboardSize.height, right: 0.0)
        self.scrollView.contentInset = contentInsets
        self.scrollView.scrollIndicatorInsets = contentInsets
        var aRect = self.view.frame
        aRect.size.height -= keyboardSize.size.height
        if (!CGRectContainsPoint(aRect, activeField.frame.origin)) {
            self.scrollView.scrollRectToVisible(activeField.frame, animated: true)
        }
    }


}

func keyboardWillBeHidden(notification: NSNotification)
{
    let contentInsets = UIEdgeInsetsZero
    self.scrollView.contentInset = contentInsets
    self.scrollView.scrollIndicatorInsets = contentInsets
}

但是我如何为textView做到这一点.我用textView的didBeginEditing尝试了相同的代码,没有任何积极的影响

简便且无需行代码的解决方案之一就是在您的应用中使用以下Pod。

IQKeyboard曼格

稍后，您只需将其导入App Delegate中，并在didfinishLaunching方法中添加以下两行代码：

  IQKeyboardManager.sharedManager().enable = true

您的问题将为整个应用程序解决。
