快速在键盘上方添加视图，但出现错误无法分配给属性：“ inputAccessoryView”是仅获取属性

Question

My scenario, I am trying to add UIView on top of the keyboard for toolbar. here, I am using below code for growing textview

https://github.com/muukii/NextGrowingTextView

I added additionally UIView in Viewcontroller top side and added below code into Viewcontroller

@IBOutlet var toolBarView: UIView!
@IBOutlet weak var growingTextView: NextGrowingTextView!

in ViewDidLoad() added below line

self.growingTextView.inputAccessoryView = toolBarView

I am getting below error, how to fix this?

Cannot assign to property: 'inputAccessoryView' is a get-only property

If I add below line

self.growingTextView.textView.inputAccessoryView = toolBarView

I am getting output like below screen in iPhone X series (Other devices working fine).

current output getting gap between toolbarview and growingTextView

Answer 1

To answer your question: The error occurs because class NextGrowingTextView is of type UIScrollView and you simply cannot change a scroll view's inputAccessoryView . You can see that in NextGrowingTextView.swift.

You should - though - be able to modify self.growingTextView.textView.inputAccessoryView .

Answer 2

You've to use

self.growingTextView.textView.inputAccessoryView = toolBarView

instead of

self.growingTextView.inputAccessoryView = toolBarView

Because growingTextView is a object instance of NextGrowingTextView which is subClass of UIScrollView and in this for textView used NextGrowingInternalTextView .
