leotextview's Introduction

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

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)

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

leotextview's Issues

Some text layout wrong when paste text

Bold & Italic in the same time

HI ! Its possible to have bold & italic in the same time ?
How can i create new style ? Like Super title who is bigger, or others
thanks

Lists cause Indentation to be stuck

After bolding a bulleted sentence

Swift 5.0 support

Bold & Italic font not set correctly when setting textView.attributedText

Have two LEOTextViews (Non-editable view and editable view).

First subclassed in Storyboard, with the ViewController written in Obj-C.
Second is initiated programmatically, with the ViewController written in Swift.

Write text and set to bold / italic in the second VC (Swift) and segue back to first VC (Obj-C). All formatting copies perfectly. Then try to segue back to the second VC (Swift) to edit again, and bold & italics are reverted back to normal text. Formatting not copied for some reason...although bullet points are copying correctly, just not bold & italic, which is strange since it copied over perfectly the first time to the non-editable view.

In both cases I'm just doing textView.attributedText = otherViewController.textView.attributedText

Bold & Italic (both)

Is there a way to apply both to selected text? Setting InputFontMode will overwrite one or the other

Toolbar not appearing properly in UITableViewController w/ UITextView in a row

I see a sudden flicker in my UITextView (the dismiss keyboard & the aA icon), but then both icons disappears (toolbar gone). Objective-C project. There shouldn't be any incompatibilities should there?

Additional features

Can't believe I've found this. Any plans on adding more features like highlighting, etc?

What is the proper way to initialize LeoTextView if using Storyboard?

nck_textStorage is nil when trying to call

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

given it is initialized in your public init method.

also, only changeCurrentParagraphToOrderedListWithOrderedList is visible publicly
