滚动表格时如何在键盘上方移动inputView

问题描述

我有一个视图控制器，其中 表格视图和表格下方的textView

I have a view controller in which it has table view and textView below the table

当我点击textView时，出现键盘，而当我点击textView之外时，键盘消失效果很好，但是我有一个问题，当我拖动(向下滚动)表格视图时，textView不会随着键盘向下移动，并且在键盘后面看到黑色背景，如下图所示

When I tap on the textView the keyboard appears and when I tap outside the textView the keyboard disapparThat works fine but I have one problem which is when I Drag(scroll Down) the table view the textView doesn't move down with the keyboard and I see black background behind the keyboard as in the below image

如何在Swift中解决此问题

How to solve this problem in Swift

更新:这是我当前的代码，其中观察到keyboardFrameChanges

Update:This is my current code that observe the keyboardFrameChanges

func keyboardFrameChanged(notification: NSNotification) {

    let dict = NSDictionary(dictionary: notification.userInfo!)
    let keyboardValue = dict.objectForKey(UIKeyboardFrameEndUserInfoKey) as! NSValue
    let bottomDistance = mainScreenSize().height - keyboardValue.CGRectValue().origin.y
     let duration = Double(dict.objectForKey(UIKeyboardAnimationDurationUserInfoKey) as! NSNumber)

    UIView.animateWithDuration(duration, animations: {
        self.inputViewConstraint!.constant = -bottomDistance
        self.view.layoutIfNeeded()
        }, completion: {
            (value: Bool) in
            self.chatTableView.scrollToBottom(animation: true)
    })

}

更新2:我通过将keyboardDismissMode从 Interactive 更改为 OnDrag

Update 2:I found a solution by changing the keyboardDismissMode from Interactive to OnDrag

chatTableView.keyboardDismissMode = UIScrollViewKeyboardDismissMode.OnDrag

一旦观察到表格中的任何拖动移动，这将立即将键盘和textView向下移动，但是如何在 Interactive 模式下(如在whatsapp聊天视图中)进行操作

This will move the keyboard and the textView immediatly to down once it observe any drag movement in the table , But how to do it in the Interactive mode like in the whatsapp chat view
