DKImagePickerController

Build Status Version Status license MIT Carthage compatible

Description

It's a Facebook style Image Picker Controller by Swift. It uses DKCamera instead of UIImagePickerController since the latter cannot be Integrated into another container, and it will raise a warning Snapshotting ... or snapshot after screen updates. in iOS 8.

Features

  • Supports both single and multiple selection.
  • Supports filtering albums and sorting by type.
  • Supports landscape and iPad and orientation switching.
  • Supports iCloud.
  • Supports UIAppearance.
  • Supports custom camera.
  • Supports custom UICollectionViewLayout.
  • Supports footer view.

Requirements

  • iOS 8.0+
  • ARC
  • Swift 3 and Xcode 8

Installation

iOS 8 and newer

DKImagePickerController is available on CocoaPods. Simply add the following line to your podfile:

# For latest release in cocoapods
pod 'DKImagePickerController'

iOS 7.x

The 3.x aren't supported before iOS 8. If you want to support iOS 7, you can look at the 2.4.3 branch that uses ALAssetsLibrary instead of using Photos.

To use Swift libraries on apps that support iOS 7, you must manually copy the files into your application project. CocoaPods only supports Swift on OS X 10.9 and newer, and iOS 8 and newer.

Swift 2.2

For Swift 2.2, use version <= 3.3.4

Swift 2.3

For Swift 2.3, use version = 3.3.5

Getting Started

Initialization and presentation

let pickerController = DKImagePickerController()

pickerController.didSelectAssets = { (assets: [DKAsset]) in
    print("didSelectAssets")
    print(assets)
}

self.presentViewController(pickerController, animated: true) {}

Customizing

/// Forces selection of tapped image immediatly.
public var singleSelect = false
    
/// The maximum count of assets which the user will be able to select.
public var maxSelectableCount = 999

/// Set the defaultAssetGroup to specify which album is the default asset group.
public var defaultAssetGroup: PHAssetCollectionSubtype?

/// The types of PHAssetCollection to display in the picker.
public var assetGroupTypes: [PHAssetCollectionSubtype] = [
    .SmartAlbumUserLibrary,
    .SmartAlbumFavorites,
    .AlbumRegular
    ]

/// Set the showsEmptyAlbums to specify whether or not the empty albums is shown in the picker.
public var showsEmptyAlbums = true

/// The type of picker interface to be displayed by the controller.
public var assetType: DKImagePickerControllerAssetType = .AllAssets

/// The predicate applies to images only.
public var imageFetchPredicate: NSPredicate?

/// The predicate applies to videos only.
public var videoFetchPredicate: NSPredicate?

/// If sourceType is Camera will cause the assetType & maxSelectableCount & allowMultipleTypes & defaultSelectedAssets to be ignored.
public var sourceType: DKImagePickerControllerSourceType = .Both

/// Whether allows to select photos and videos at the same time.
public var allowMultipleTypes = true

/// If YES, and the requested image is not stored on the local device, the Picker downloads the image from iCloud.
public var autoDownloadWhenAssetIsInCloud = true

/// Determines whether or not the rotation is enabled.
public var allowsLandscape = false

/// The callback block is executed when user pressed the cancel button.
public var didCancel: (() -> Void)?
public var showsCancelButton = false

/// The callback block is executed when user pressed the select button.
public var didSelectAssets: ((assets: [DKAsset]) -> Void)?

/// It will have selected the specific assets.
public var defaultSelectedAssets: [DKAsset]?
Exporting to file
/**
    Writes the image in the receiver to the file specified by a given path.
*/
public func writeImageToFile(path: String, completeBlock: (success: Bool) -> Void)

/**
    Writes the AV in the receiver to the file specified by a given path.

    - parameter presetName:    An NSString specifying the name of the preset template for the export. See AVAssetExportPresetXXX.
*/
public func writeAVToFile(path: String, presetName: String, completeBlock: (success: Bool) -> Void)
Customize Navigation Bar

You can easily customize the appearance of navigation bar using the appearance proxy.

UINavigationBar.appearance().titleTextAttributes = [
    NSFontAttributeName : UIFont(name: "Optima-BoldItalic", size: 21)!,
    NSForegroundColorAttributeName : UIColor.redColor()
]

Hides camera

pickerController.sourceType = .Photo

Quickly take a picture

pickerController.sourceType = .Camera

Customize footer view and UI color

Create a custom camera

You can give a class that implements the DKImagePickerControllerUIDelegate protocol to customize camera.
The following code uses a UIImagePickerController:

public class CustomUIDelegate: DKImagePickerControllerDefaultUIDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    
    var didCancel: (() -> Void)?
    var didFinishCapturingImage: ((image: UIImage) -> Void)?
    var didFinishCapturingVideo: ((videoURL: NSURL) -> Void)?
    
    public override func imagePickerControllerCreateCamera(imagePickerController: DKImagePickerController,
                                                           didCancel: (() -> Void),
                                                           didFinishCapturingImage: ((image: UIImage) -> Void),
                                                           didFinishCapturingVideo: ((videoURL: NSURL) -> Void)
                                                           ) -> UIViewController {
        self.didCancel = didCancel
        self.didFinishCapturingImage = didFinishCapturingImage
        self.didFinishCapturingVideo = didFinishCapturingVideo
        
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.sourceType = .Camera
        picker.mediaTypes = [kUTTypeImage as String, kUTTypeMovie as String]
        
        return picker
    }
    
    // MARK: - UIImagePickerControllerDelegate methods
    
    public func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        let mediaType = info[UIImagePickerControllerMediaType] as! String
        
        if mediaType == kUTTypeImage as String {
            let image = info[UIImagePickerControllerOriginalImage] as! UIImage
            self.didFinishCapturingImage?(image: image)
        } else if mediaType == kUTTypeMovie as String {
            let videoURL = info[UIImagePickerControllerMediaURL] as! NSURL
            self.didFinishCapturingVideo?(videoURL: videoURL)
        }
    }
    
    public func imagePickerControllerDidCancel(picker: UIImagePickerController) {
        self.didCancel?()
    }
    
}

How to use in Objective-C

If you use CocoaPods

  • Adding the following two lines into your Podfile:

    pod 'DKImagePickerController'
    use_frameworks!
  • Importing it into your Objective-C file:

    #import <DKImagePickerController/DKImagePickerController-Swift.h>

If you use it directly in your project

See also:Swift and Objective-C in the Same Project

  • Drag and drop the DKCamera and DKImageManager and DKImagePickerController to your project

  • Importing it into your Objective-C file:

    #import "YourProductModuleName-Swift.h"

then you can:

DKImagePickerController *pickerController = [DKImagePickerController new];
pickerController.assetType = DKImagePickerControllerAssetTypeAllAssets;
pickerController.showsCancelButton = NO;
pickerController.showsEmptyAlbums = YES;
pickerController.allowMultipleTypes = YES;
pickerController.defaultSelectedAssets = @[];
pickerController.sourceType = DKImagePickerControllerSourceTypeBoth;
//  pickerController.assetGroupTypes    // unavailable
//  pickerController.defaultAssetGroup  // unavailable

 [pickerController setDidSelectAssets:^(NSArray * __nonnull assets) {
     NSLog(@"didSelectAssets");
 }];
 
 [self presentViewController:pickerController animated:YES completion:nil];
