Installation

Cocoapods

If you have Cocoapods 0.36+ installed, you can use Cocoapods to include RichEditorView into your project. Add the following to your Podfile:

pod "RichEditorView"
use_frameworks!

Note: the use_frameworks! is required for pods made in Swift.

Carthage

Add the following to your Cartfile:

github 'cjwirth/RichEditorView'

Using RichEditorView

RichEditorView makes no assumptions about how you want to use it in your app. It is a plain UIView subclass, so you are free to use it wherever, however you want.

Most basic use:

editor = RichEditorView(frame: self.view.bounds)
editor.setHTML("<h1>My Awesome Editor</h1>Now I am editing in <em>style.</em>")
self.view.addSubview(editor)

Editing Text

To change the styles of the currently selected text, you just call methods directly on the RichEditorView:

editor.bold()
editor.italic()
editor.setTextColor(UIColor.redColor())

If you want to show the editing toolbar RichEditorToolbar, you will need to handle displaying it (KeyboardManager.swift in the sample project is a good start). But configuring it is as easy as telling it which options you want to enable, and telling it which RichEditorView to work on.

let toolbar = RichEditorToolbar(frame: CGRectMake(0, 0, 320, 44))
toolbar.options = RichEditorOptions.all()
toolbar.editor = editor // Previously instantiated RichEditorView

Some actions require user feedback (such as select an image, choose a color, etc). In this cases you can conform to the RichEditorToolbarDelegate and react to these actions, and maybe display some custom UI. For example, from the sample project, we just select a random color:

private func randomColor() -> UIColor {
    let colors = [
        UIColor.redColor(),
        UIColor.orangeColor(),
        UIColor.yellowColor(),
        UIColor.greenColor(),
        UIColor.blueColor(),
        UIColor.purpleColor()
    ]

    let color = colors[Int(arc4random_uniform(UInt32(colors.count)))]
    return color
}

func richEditorToolbarChangeTextColor(toolbar: RichEditorToolbar) {
    let color = randomColor()
    toolbar.editor?.setTextColor(color)
}

Advanced Editing

If you need even more flexibility with your options, you can add completely custom actions, by either making an object that conforms the the RichEditorOption protocol, or configuring a RichEditorOptionItem object, and adding it to the toolbar's options:

let clearAllItem = RichEditorOptionItem(image: UIImage(named: "clear"), title: "Clear") { toolbar in
    toolbar?.editor?.setHTML("")
    return
}
toolbar.options = [clearAllItem]
