JustPhotoPicker is a simple and minimalistic photo picker for iOS written in Swift.

Initially, the project was made for personal purposes, but it was decided to make it publicly available for use and contribution in improvement.

Installation

Using CocoaPods

You can use CocoaPods to install JustPhotoPicker by adding folowing lines to your Podfile:

platform :ios, '13.0'
use_frameworks!

target 'ApplicationName' do
    pod 'JustPhotoPicker'
end

Then just write the command in the terminal to install:

$ pod install

Using Swift Package Manager

You can use Swift Package Manager to install JustPhotoPicker using Xcode:

1. Open your project in Xcode
2. Open "File" -> "Swift Packages" -> "Add Package Dependency..."
3. Paste the repository URL: https://github.com/igooor-bb/JustPhotoPicker
4. Click "Next" a couple of times and finish adding

Info.plist

To make your application have access to photos, add the following entity to the file Info.plist:

• Privacy - Photo Library Usage Description

<key>NSPhotoLibraryUsageDescription</key>
<string>Some description</string>

Usage in UIKit

First of all, import the module JustPhotoPicker into a file with your view controller:

import JustPhotoPicker

Configuration

You can change some visual and logical parameters using the JustPhotoPickerConfiguration structure. Set all the options you want and create a picker with configuration as a parameter:

var config = JustPhotoPickerConfiguration()
config.selectionLimit = 2
config.isSelectionRequired = true
// Configuration vibes...
let photoPicker = JustPhotoPicker(configuration: config)

Processing the result

Using the delegate

To obtain the selected photos or the fact that the photos were not selected, the JustPhotoPickerDelegate protocol can be used.

1. Setup a delegate for your photo picker:

photoPicker.photoPickerDelegate = self

2. Make your view controller conform the delegate protocol and implement both required methods:

extension ViewController: JustPhotoPickerDelegate {
  func didSelect(with photoPicker: JustPhotoPicker, images: [UIImage]) {
    print("Selected \(image.count) images")
  }

  func didNotSelect(with photoPicker: JustPhotoPicker) {
    print("Did not select any images")
  }
}

Using the closure

You also can use didFinishPicking closure of JustPhotoPicker class to obtain the selected photos:

let photoPicker = JustPhotoPicker(configuration: config)
photoPicker.didFinishPicking = { images, canceled in
  if canceled {
    print("Did not select any images")
    return
  }

  print("Selected \(images.count) images")
}

The closure takes two parameters. The first one is either a list of selected images or an empty list in case if a user did not select any. The second parameter is a boolean flag indicating whether a user canceled the selection.

Display

When you are ready to start picking photos, display the picker in the standard way:

present(photoPicker, animated: true)

Usage in SwiftUI

Recently we added SwiftUI support for JustPhotoPicker. All you need to do is to call JustPhotoPickerView in the same way in the body of your SwiftUI:

VStack {
  Button("Select photo") {
    showingPicker = true
  }
}
.sheet(isPresented: $showingPicker) {
  JustPhotoPickerView(configuration: pickerConfig)
    .onFinish { images in
      print("Selected \(images.count) images")
    }
    .onCancel {
      print("Did not select any images")
    }
}

Configuration properties

The following are some of the possible settings for the picker, which you can also find in the JustPhotoPickerConfiguration structure:

config.selectionLimit = 2
config.isSelectionRequired = true
config.showsBottomDescriptionLabel = true
config.portraitModeCellsInRow = 3
config.landscapeModeCellsInRow = 6
config.backgroundColor = .white
config.accentColor = .systemPink
config.albumThumbnailCornerRaduis = 5
config.photoCardCornerRaduis = 0
config.startsOnScreen = .photos
config.hidesEmptyAlbumLabel = true
config.showsPhotoPreview = true
config.allowsPhotoPreviewZoom = false
// Configuration vibes...
