Summary

• How to change the left (add) button in messageInputView with a custom button?

Guide & Snippet

• If you want to change the left button of SBUMessageInputView,
• Please set up addButton with your custom button and set onClickAddButton(_:) as its action.
• And you can customize the action of the left(add) button by overriding onClickAddbutton(_:) in SBUMessageInputView.
• The default action is to show menu items: camera, photo library, and document.
• But, if you want to customize the event only when the menu item was selected, then override messageInputView(_:didSelectResource:).

• When the user tapped the addButton, the flow is like below:
• onClickAddButton
• → show menu items as action sheets
• → user selects item
• → didSelectActionSheetItem(index:identifier:)
• → messageInputView(_:didSelectResource:)
