`PDFGenerator` is a simple PDF generator that generates with `UIView`, `UIImage`, ...etc .
```swift
do {
let page: [PDFPage] = [
.whitePage(CGSize(width: 200.0, height: 100.0)),
.image(image1)
.image(image2)
.imagePath(lastPageImagePath)
.whitePage(CGSize(width: 200.0, height: 100.0))
]
let path = NSTemporaryDirectory().appending("sample1.pdf")
try PDFGenerator.generate(page, to: path, password: "123456")
} catch let error {
print(error)
}
```
## Features
- **Swift 5 is ready** :pray:
- Multiple pages support.
- Also generate PDF with `image path`, `image binary`, `image ref (CGImage)`
- Good memory management.
- UIScrollView support : If view is `UIScrollView`, `UITableView`, `UICollectionView`, `UIWebView`, drawn whole content.
- Outputs as binary(`Data`) or writes to Disk(in given file path) directly.
- Corresponding to Error-Handling. Strange PDF has never been generated!!.
- DPI support. : Default dpi is 72.
- Password protection support.
## Requirements
- iOS 9.0+
- Xcode 11+
- Swift 5.1
## Installation
### Carthage
- Add the following to your *Cartfile*:
```bash
github "sgr-ksmt/PDFGenerator" ~> 3.1
```
- Then run command:
```bash
$ carthage update
```
- Add the framework as described.
Details: [Carthage Readme](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application)
#### CocoaPods
**PDFGenerator** is available through [CocoaPods](http://cocoapods.org). To install
it, simply add the following line to your Podfile:
```ruby
pod 'PDFGenerator', '~> 3.1'
```
and run `pod install`
## Usage
### Generate from view(s) or image(s)
- UIView → PDF
```swift
func generatePDF() {
let v1 = UIScrollView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
let v3 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
v1.backgroundColor = .red
v1.contentSize = CGSize(width: 100.0, height: 200.0)
v2.backgroundColor = .green
v3.backgroundColor = .blue
let dst = URL(fileURLWithPath: NSTemporaryDirectory().appending("sample1.pdf"))
// outputs as Data
do {
let data = try PDFGenerator.generated(by: [v1, v2, v3])
try data.write(to: dst, options: .atomic)
} catch (let error) {
print(error)
}
// writes to Disk directly.
do {
try PDFGenerator.generate([v1, v2, v3], to: dst)
} catch (let error) {
print(error)
}
}
```
`Also PDF can generate from image(s), image path(s) same as example.`
### Generate from PDFPage object
- (UIVIew or UIImage) → PDF
Use `PDFPage`.
```swift
public enum PDFPage {
case whitePage(CGSize) // = A white view
case view(UIView)
case image(UIImage)
case imagePath(String)
case binary(Data)
case imageRef(CGImage)
}
```
```swift
func generatePDF() {
let v1 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
v1.backgroundColor = .red
let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
v2.backgroundColor = .green
let page1 = PDFPage.View(v1)
let page2 = PDFPage.View(v2)
let page3 = PDFPage.WhitePage(CGSizeMake(200, 100))
let page4 = PDFPage.Image(UIImage(contentsOfFile: "path/to/image1.png")!)
let page5 = PDFPage.ImagePath("path/to/image2.png")
let pages = [page1, page2, page3, page4, page5]
let dst = NSTemporaryDirectory().appending("sample1.pdf")
do {
try PDFGenerator.generate(pages, to: dst)
} catch (let e) {
print(e)
}
}
```
### Generate custom dpi PDF
```swift
// generate dpi300 PDF (default: 72dpi)
func generatePDF() {
let v1 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
v1.backgroundColor = .red
let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
v2.backgroundColor = .green
let page1 = PDFPage.View(v1)
let page2 = PDFPage.View(v2)
let pages = [page1, page2]
let dst = NSTemporaryDirectory().appending("sample1.pdf")
do {
try PDFGenerator.generate(pages, to: dst, dpi: .dpi_300)
} catch (let e) {
print(e)
}
}
```
### Password protection
```swift
// generate PDF with password: 123456
func generatePDF() {
let v1 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
v1.backgroundColor = .red
let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
v2.backgroundColor = .green
let page1 = PDFPage.view(v1)
let page2 = PDFPage.view(v2)
let pages = [page1, page2]
let dst = NSTemporaryDirectory().appending("sample1.pdf")
do {
try PDFGenerator.generate(pages, to: dst, password: "123456")
// or use PDFPassword model
try PDFGenerator.generate(pages, to: dst, password: PDFPassword("123456"))
// or use PDFPassword model and set user/owner password
try PDFGenerator.generate(pages, to: dst, password: PDFPassword(user: "123456", owner: "abcdef"))
} catch let error {
print(error)
}
}
```
