Requirements

Installation

WSPagePreview is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "WSPagePreview"

How to use

1. Create and link IBOutlet scrollView and var WSPagePreview

@IBOutlet weak var scrollView: UIScrollView!
var pagePreview: WSPagePreview?

2. Inside viewDidLoad function, init and add a delegate (don't forget to include WSPagePreviewDelegate)

// Convenience init with default settings (Paper size: A4, Margin: 0 cm)
pagePreview = WSPagePreview()

// Default init requires you to specify the paper size and page margin
// pagePreview = WSPagePreview(pageSize: CGSize, pageMargin: UIEdgeInsets, fontSize: CGFloat)

pagePreview?.delegate = self

3. Inside viewDidLayoutSubviews function, call the initDefaultSettings(UIScrollView)

pagePreview?.initDefaultSettings(scrollView)

4. Implement this delegate method

func WSPagePreviewSetTextContent(pagePreview: WSPagePreview) -> String {
    
    // Do your text processing here

    return text
}

5. Done! or do you want more? See the customize page option below!

(Optional) Customize Page Option

In case you need to customize some properties to adjust with your preferences, you can use this helpful method! Ideally, you should call all of this available function right after initDefaultSettings(UIScrollView) inside the viewDidLayoutSubviews function.

####To show a page control

func WSPagePreviewShowPageControl(pagePreview: WSPagePreview, pageControl: UIPageControl) {

    // Do your page control styling here
    ...

    view.addSubview(pageControl)
}

####To set custom margin

let margin = UIEdgeInsetsMake(20.0, 20.0, 20.0, 20.0)
pagePreview?.setPageMargin(margin)

####To set custom horizontal margin

pagePreview?.setPageMarginHorizontally(20.0, right: 20.0)

####To set custom vertical margin

pagePreview?.setPageMarginVertically(20.0, bottom: 20.0)

####To set custom page size

let size = CGSize(width: 500.0, height: 500.0)
pagePreview?.setPageSize(size)

####To set custom font size

pagePreview?.setFontSize(14.0)

#####*Psstt! WSPagePreview automatically adjust the font size based on paper size so you don't have to worry about that, you're welcome!
