How to add scrolling for UIBarButtonItem buttons on UIToolbar (to place many buttons on the toolbar)?

For Swift

let's just say i want to add 7 UIBarButtonItem's to my UIToolBar

First Create a scrollView, then add toolBar as subview

// In viewDidLoad

let scrollView = UIScrollView(frame: CGRect(x: 0, y: view.frame.height-44, width: view.frame.width, height: 50))

    let toolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: 1000, height: scrollView.frame.height))

    let btn1 = UIBarButtonItem()
    let btn2 = UIBarButtonItem()
    let btn3 = UIBarButtonItem()
    let btn4 = UIBarButtonItem()
    let btn5 = UIBarButtonItem()
    let btn6 = UIBarButtonItem()
    let btn7 = UIBarButtonItem()
    toolBar.items = [btn1, btn2, btn3, btn4, btn5, btn6, btn7]

scrollView.addSubview(toolBar)

// The below line is important for scrollView to work
scrollView.contentSize = CGSize(width: 1000, height: 50)

Lastly add scrollView as your textField inputAccessoryView

textField.inputAccessoryView = scrollView

I hope it helps you :]
