Usage

• use delegate & custom cell

class ViewController: UIViewController,TLPhotosPickerViewControllerDelegate {
    var selectedAssets = [TLPHAsset]()
    @IBAction func pickerButtonTap() {
        let viewController = TLPhotosPickerViewController()
        viewController.delegate = self
        var configure = TLPhotosPickerConfigure()
        //configure.nibSet = (nibName: "CustomCell_Instagram", bundle: Bundle.main) // If you want use your custom cell..
        self.present(viewController, animated: true, completion: nil)
    }
    //TLPhotosPickerViewControllerDelegate
    func dismissPhotoPicker(withTLPHAssets: [TLPHAsset]) {
        // use selected order, fullresolution image
        self.selectedAssets = withTLPHAssets
    }
    func dismissPhotoPicker(withPHAssets: [PHAsset]) {
        // if you want to used phasset. 
    }
    func photoPickerDidCancel() {
        // cancel
    }
    func dismissComplete() {
        // picker viewcontroller dismiss completion
    }
    func didExceedMaximumNumberOfSelection(picker: TLPhotosPickerViewController) {
        // exceed max selection
    }
}

//Custom Cell must subclass TLPhotoCollectionViewCell

class CustomCell_Instagram: TLPhotoCollectionViewCell {

}

//If you want custom camera cell?
//only used camera cell
[Sample](https://github.com/tilltue/TLPhotoPicker/blob/master/Example/TLPhotoPicker/CustomCameraCell.swift)

@objc open func selectedCell()
@objc open func willDisplayCell()
@objc open func endDisplayingCell()

• use closure

    convenience public init(withPHAssets: (([PHAsset]) -> Void)? = nil, didCancel: ((Void) -> Void)? = nil)
    convenience public init(withTLPHAssets: (([TLPHAsset]) -> Void)? = nil, didCancel: ((Void) -> Void)? = nil)
    open var didExceedMaximumNumberOfSelection: ((TLPhotosPickerViewController) -> Void)? = nil
    open var dismissCompletion: (() -> Void)? = nil

class ViewController: UIViewController,TLPhotosPickerViewControllerDelegate {
    var selectedAssets = [TLPHAsset]()
    @IBAction func pickerButtonTap() {
        let viewController = TLPhotosPickerViewController(withTLPHAssets: { [weak self] (assets) in // TLAssets
            self?.selectedAssets = assets
        }, didCancel: nil)
        viewController.didExceedMaximumNumberOfSelection = { [weak self] (picker) in
            //exceed max selection
        }
        viewController.selectedAssets = self.selectedAssets
        self.present(viewController, animated: true, completion: nil)
    }
}

• TLPHAsset

public struct TLPHAsset {
    public enum AssetType {
        case photo,video,livePhoto
    }
    // phasset 
    public var phAsset: PHAsset? = nil
    // selected order index
    public var selectedOrder: Int = 0
    // asset type
    public var type: AssetType
    // get full resolution image 
    public var fullResolutionImage: UIImage?
    // get video file size (async)
    public func videoSize(options: PHVideoRequestOptions? = nil, completion: @escaping ((Int)->Void))
    // get async icloud image (download)
    @discardableResult
    public func cloudImageDownload(progressBlock: @escaping (Double) -> Void, completionBlock:@escaping (UIImage?)-> Void ) -> PHImageRequestID?
    // get original asset file name
    public var originalFileName: String?
}

Customize

let viewController = TLPhotosPickerViewController()
var configure = TLPhotosPickerConfigure()
viewController.configure = configure

public struct TLPhotosPickerConfigure {
    public var defaultCameraRollTitle = "Camera Roll"
    public var tapHereToChange = "Tap here to change"
    public var usedCameraButton = true
    public var usedPrefetch = false
    public var allowedLivePhotos = true
    public var allowedVideo = true
    public var allowedVideoRecording = true
    public var maxVideoDuration:TimeInterval? = nil
    public var autoPlay = true
    public var muteAudio = true
    public var mediaType: PHAssetMediaType? = nil
    public var numberOfColumn = 3
    public var maxSelectedAssets: Int? = nil //default: inf
    public var singleSelectedMode = false
    public var selectedColor = UIColor(red: 88/255, green: 144/255, blue: 255/255, alpha: 1.0)
    public var cameraBgColor = UIColor(red: 221/255, green: 223/255, blue: 226/255, alpha: 1)
    public var cameraIcon = TLBundle.podBundleImage(named: "camera")
    public var videoIcon = TLBundle.podBundleImage(named: "video")
    public var placeholderIcon = TLBundle.podBundleImage(named: "insertPhotoMaterial")
    public var nibSet: (nibName: String, bundle:Bundle)? = nil // custom cell
    public var cameraCellNibSet: (nibName: String, bundle:Bundle)? = nil // custom camera cell
    public init() {
    }
}

//customizable photos picker viewcontroller
class CustomPhotoPickerViewController: TLPhotosPickerViewController {
    override func makeUI() {
        super.makeUI()
        self.customNavItem.leftBarButtonItem = UIBarButtonItem.init(barButtonSystemItem: .stop, target: nil, action: #selector(customAction))
    }
    func customAction() {
        self.dismiss(animated: true, completion: nil)
    }
}
