🐬A high-performance rich editor develop with swift on iOS platform, based on TextKit.

LEOTextView

LEOTextView is a very high-performance rich editor. Because it's a subclass of UITextView, not UIWebView. All of code by TextKit framework.

Features

• Bold Text
• Italic Text
• Unordered List
• Ordered List
• List auto indentation
• Undo and Redo
• Rich Text Copy & Paste

Requirements

Xcode 8.3 or newer

Tag	Swift
<= 0.4.x	2.2
>= 0.5.0	3.0
>= 0.7.0	4.0

Usage

Not extends any class, not EditorController and so on...

You can embed LEOTextView to anywhere that you want.

// Init TextView
let textView = LEOTextView(frame: self.view.bounds, textContainer: NSTextContainer())

// If you want to use built-in toolbar, call it.
textView.enableToolbar()

// add to View
self.view.addSubview(textView)

Done.

UITextViewDelegate

Some feature I use delegate method, so LEOTextView is delegate self. And provide another delegate property named leo_delegate

public var leo_delegate: UITextViewDelegate?

Public methods

Type transform

public func changeCurrentParagraphTextWithInputFontMode(mode: LEOInputFontMode)
public func changeSelectedTextWithInputFontMode(mode: LEOInputFontMode)

public func changeCurrentParagraphToOrderedList(orderedList isOrderedList: Bool, listPrefix: String)

Text attributes persistent

Get JSON by

public func textAttributesJSON() -> String

This method return a JSON string that contains all attributes needs to reload.

A unordered list

• A
• B
• C

convert to JSON look like:

{
  "text": "- A\n- B\n- C",
  "attributes": [
  {
    "location": 0,
    "length": 11,
    "fontType": "normal",
    "name": "NSFont"
  },
  {
    "location": 0,
    "length": 11,
    "listType": 3,
    "name": "NSParagraphStyle"
  }
  ]
}

Set JSON and display to UITextView by

public func setAttributeTextWithJSONString(jsonString: String)

Or just set attributes only by

public func setAttributesWithJSONString(jsonString: String)
