Installation

Cocoapods

If you have Cocoapods 1.0+ installed, you can use Cocoapods to include RichEditorView into your project. Add the following to your Podfile:

pod 'RichEditorView', :git => 'https://github.com/cbess/RichEditorView.git', :tag => '4.0'

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

Carthage

Add the following to your Cartfile:

github 'cbess/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: view.bounds)
editor.html = "<h1>Jesus is God.</h1> He died for our sins and rose from the dead by His own power. Repent and believe the gospel!"
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(.red)

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 = RichEditorDefaultOption.all
toolbar.editor = editor // Previously instantiated RichEditorView
editor.inputAccessoryView = toolbar

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.red,
        UIColor.orange,
        UIColor.yellow,
        UIColor.green,
        UIColor.blue,
        UIColor.purple
    ]

    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?.html = ""
    return
}
toolbar.options = [clearAllItem]
