Create new single view application Xcode project by naming as”DemoPdf”. Set the values as follows and save it as a folder on your desktop.
Begin the Project:
Go to the mainStoryboard and Add a button by giving name “Generate PDF” as and a Textview to the main storyboard from the Object library.Now connect the outlet by naming as “ txtView ” for the textview and the action method ”btnGeneratePDF” for the button.
Here is the complete Code in ViewController.swift file
import UIKit
class ViewController: UIViewController {
//make the ordinary variable for pageSize of pdf we obtain after generating.
var pageSize:CGSize!
// make the outlet for the textview.
@IBOutlet weak var txtView: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
}
// make the action method for generating into a pdf file.
@IBAction func btnGeneratePDF(sender: AnyObject) {
pageSize = CGSizeMake (850, 1100)
let fileName: NSString = “kindle.pdf”
let path:NSArray = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let documentDirectory: AnyObject = path.objectAtIndex(0)
let pdfPathWithFileName = documentDirectory.stringByAppendingPathComponent(fileName as String)
self.generatePDFs(pdfPathWithFileName)
//lines written to get the document directory path for the generated pdf file.
if let documentsPath = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first?.path {
print(documentsPath)
// “var/folder/…/documents ” copy the full path
}
}
// method to generate pdf file to display the text and image in pdf file.
func generatePDFs(filePath: String) {
UIGraphicsBeginPDFContextToFile(filePath, CGRectZero, nil)
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 768, 1024), nil)
//toPDF()
self.drawBackground()
self.drawImage()
self.drawText()
UIGraphicsEndPDFContext()
}
// draw the custom background view to display the text and image in pdf.
func drawBackground () {
let context:CGContextRef = UIGraphicsGetCurrentContext()!
let rect:CGRect = CGRectMake(0, 0, pageSize.width, pageSize.height)
CGContextSetFillColorWithColor(context, UIColor.brownColor().CGColor)
CGContextFillRect(context, rect)
}
// draw the custom textview to display the text enter into it into pdf.
func drawText(){
let context:CGContextRef = UIGraphicsGetCurrentContext()!
let font = UIFont(name: “HelveticaNeue-UltraLight”, size: CGFloat(20))!
CGContextSetFillColorWithColor(context, UIColor.orangeColor().CGColor)
let textRect : CGRect = CGRectMake(200, 350, ((self.txtView).frame).size.width, ((self.txtView).frame).size.height)
let myString : NSString = self.txtView.text
let paraStyle = NSMutableParagraphStyle()
paraStyle.lineSpacing = 6.0
let fieldFont = UIFont(name: “Helvetica Neue”, size: 30)
let parameters: NSDictionary = [ NSFontAttributeName:font, NSParagraphStyleAttributeName:paraStyle ,NSFontAttributeName: fieldFont!]
myString.drawInRect(textRect, withAttributes: parameters as? [String : AnyObject])
}
// draw the custom image to display into pdf with the given text you enter into textview
func drawImage(){
let imgRect:CGRect = CGRectMake(284, 50, 200, 200)
let image : UIImage = UIImage(named:“logo.png”)!
image.drawInRect(imgRect)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
} }
