Swift 3 / IQKeyboardManager : How do you change background color of toolbar , done color, arrow colors?

You can change the appearance of Next/Previous(arrow) and Done buttons color by setting tintColor of the toolbar using below code.

To change arrow and done button colors to red:

IQKeyboardManager.shared.toolbarTintColor = .red

To hide text title on the toolbar in the middle

IQKeyboardManager.shared.shouldShowToolbarPlaceholder = false

I haven't find any property to change bar color but can change background color of IQToolbar class itself. If you find any, then add here for other's reference.

    IQKeyboardManager.shared.toolbarBarTintColor = .red

This is changing the toolbar bg color. It is actually quite easy to understand just by reading IQKeyboardManager code comments ( if you first familiar with UIKit itself)
