OKSGutteredCodeView is a swift library that provides a UIView subclass that has a textview
with a gutter to the left that automatically counts line numbers.
This view can be easily initialized like any other view or used in a storyboard by dragging
in a UIView and setting it’s class to OKSGutteredTextView


The preferred method for setting up OKSGutteredCodeView in your project is via Cocoa Pods

pod 'OKSGutteredCodeView', '~> 0.3'

For more information on using CocoaPods read the getting started guide at


This view provides several convenance methods for customizing the look of the view and a test app to see them in use

// set the background color of the line number gutter
func setGutterBackgroundColor(color: UIColor)

//set font color
func addFontColor(color: UIColor)

//set background color for the textview
func setTextViewBackgroundColor(color: UIColor)

//set the font for the text used in both the gutter and the textview
func setfont(font: UIFont) 

//programaticly get the font set on the textview
func getFont() -> UIFont

//set the text displayed in the textview programticly
func setText(text: String) 

//set attributed text in the textview
func setAttributedText(text: NSAttributedString)

//append text to the end of the text view
func appendText(text: String)

//insert text a the point the custer is currently at
func insertTextAtCurser(text: String)

//programaticly pull text in the textview
func getText() -> String

//add a toolbar to the keyboard
func addTextViewAccessoryView(toolbar: UIToolbar)


OKSGutteredCodeView also employs a protocol ‘CodeViewDelegate’ to pass information about
events that it’s performing to a delegate object. The following are CodeViewDelegate’s methods.

func textUpdated(text: String)
//This is called when ever the text is updated. This can be useful for parsing user input to
//implement your own syntax highlighting.

func keyboardWillAppear(notification: Notification)
//This is called whenever the keyboard is about to appear.

func keyboardWillHide(_ notification: Notification)
//Called when the keyboard is about to be dismissed.
