target 'MyApp'
pod 'YPImagePicker'

Using Carthage

Add github "Yummypets/YPImagePicker" to your Cartfile and run carthage update. If unfamiliar with Carthage then checkout their Getting Started section.

github "Yummypets/YPImagePicker"

Plist entries

In order for your app to access camera and photo libraries, you'll need to ad these plist entries :

Privacy - Camera Usage Description (photo/videos)
Privacy - Photo Library Usage Description (library)
Privacy - Microphone Usage Description (videos)

<key>NSCameraUsageDescription</key>
<string>yourWording</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>yourWording</string>
<key>NSMicrophoneUsageDescription</key>
<string>yourWording</string>

Configuration

var config = YPImagePickerConfiguration()
config.library.mediaType = .photoAndVideo
config.library.onlySquare  = false
config.onlySquareImagesFromCamera = true
config.targetImageSize = .original
config.usesFrontCamera = true
config.showsFilters = true
config.filters = [YPFilterDescriptor(name: "Normal", filterName: ""),
                  YPFilterDescriptor(name: "Mono", filterName: "CIPhotoEffectMono")]
config.shouldSaveNewPicturesToAlbum = true
config.video.compression = AVAssetExportPresetHighestQuality
config.albumName = "MyGreatAppName"
config.screens = [.library, .photo, .video]
config.startOnScreen = .library
config.video.recordingTimeLimit = 10
config.video.libraryTimeLimit = 20
config.showsCrop = .rectangle(ratio: (16/9))
config.wordings.libraryTitle = "Gallery"
config.hidesStatusBar = false
config.overlayView = myOverlayView
config.library.maxNumberOfItems = 5
config.isScrollToChangeModesEnabled = false

// Build a picker with your configuration
let picker = YPImagePicker(configuration: config)

Default Configuration

// Set the default configuration for all pickers
YPImagePickerConfiguration.shared = config

// And then use the default configuration like so:
let picker = YPImagePicker()

Usage

First things first import YPImagePicker.

The picker only has one callback didFinishPicking enabling you to handle all the cases. Let's see some typical use cases 🤓

Single Photo

let picker = YPImagePicker()
picker.didFinishPicking { [unowned picker] items, _ in
    if let photo = items.singlePhoto {
        print(photo.fromCamera) // Image source (camera or library)
        print(photo.image) // Final image selected by the user
        print(photo.originalImage) // original image selected by the user, unfiltered
        print(photo.modifiedImage) // Transformed image, can be nil
        print(photo.exifMeta) // Print exif meta data of original image.
    }
    picker.dismiss(animated: true, completion: nil)
}
present(picker, animated: true, completion: nil)

Single video

// Here we configure the picker to only show videos, no photos.
var config = YPImagePickerConfiguration()
config.screens = [.library, .video]
config.libraryMediaType = .video

let picker = YPImagePicker(configuration: config)
picker.didFinishPicking { [unowned picker] items, _ in
    if let video = items.singleVideo {
        print(video.fromCamera)
        print(video.thumbnail)
        print(video.url)
    }
    picker.dismiss(animated: true, completion: nil)
}
present(picker, animated: true, completion: nil)

As you can see singlePhoto and singleVideo helpers are here to help you handle single media which are very common, while using the same callback for all your use-cases \o/

Multiple selection

To enable multiple selection make sure to set library.maxNumberOfItems in the configuration like so:

var config = YPImagePickerConfiguration()
config.library.maxNumberOfItems = 3
let picker = YPImagePicker(configuration: config)

Then you can handle multiple selection in the same callback you know and love :

picker.didFinishPicking { [unowned picker] items, cancelled in
    for item in items {
        switch item {
        case .photo(let photo):
            print(photo)
        case .video(let video):
            print(video)
        }
    }
    picker.dismiss(animated: true, completion: nil)
}

Handle Cancel event (if needed)

picker.didFinishPicking { [unowned picker] items, cancelled in
    if cancelled {
        print("Picker was canceled")
    }
    picker.dismiss(animated: true, completion: nil)
}

That's it !

Languages

🇺🇸 English, 🇪🇸 Spanish, 🇫🇷 French 🇷🇺 Russian, 🇳🇱 Dutch, 🇧🇷 Brazilian, 🇹🇷 Turkish, Arabic, 🇩🇪 German, 🇮🇹 Italian, 🇯🇵 Japanese, 🇨🇳 Chinese

If your language is not supported, you can still customize the wordings via the configuration.wordings api:

config.wordings.libraryTitle = "Gallery"
config.wordings.cameraTitle = "Camera"
config.wordings.next = "OK"

Better yet you can submit an issue or pull request with your Localizable.strings file to add a new language !

UI Customization

We tried to keep things as native as possible, so this is done mostly through native Apis.

Navigation bar color

let coloredImage = UIImage(color: .red)
UINavigationBar.appearance().setBackgroundImage(coloredImage, for: UIBarMetrics.default)
// UIImage+color helper https://stackoverflow.com/questions/26542035/create-uiimage-with-solid-color-in-swift

Navigation bar fonts

let attributes = [NSAttributedStringKey.font : UIFont.systemFont(ofSize: 30, weight: .bold) ]
UINavigationBar.appearance().titleTextAttributes = attributes // Title fonts
UIBarButtonItem.appearance().setTitleTextAttributes(attributes, for: .normal) // Bar Button fonts

Navigation bar Text colors

UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor : UIColor.yellow ] // Title color
UINavigationBar.appearance().tintColor = .red // Left. bar buttons
config.colors.tintColor = .green // Right bar buttons (actions)

Original Project & Author

This project has been first inspired by Fusuma Considering the big code, design changes and all the additional features added along the way, this moved form a fork to a standalone separate repo, also for discoverability purposes. Original Fusuma author is ytakz
