TLPhotoPicker enables application to pick images and videos from multiple smart album in iOS, similar to the current facebook app.
Facebook Picker | TLPhotoPicker |
---|---|
- support smart album collection.
- camera roll, selfies, panoramas, favorites, videos, custom users album
- selected order index.
- playback video and live photos.
- just one. playback first video or live Photo in bounds of visible cell.
- display video duration.
- async phasset request and displayed cell.
- scrolling performance is better than facebook in displaying video assets collection.
- custom cell
- custom display and selection rules
- reload of changes that occur in the Photos library.
- support iCloud Photo Library
Smart album collection | LivePhotoCell | VideoPhotoCell | PhotoCell | CustomCell(instagram) |
---|---|---|---|---|
Custom Camera Cell
Live CameraCell |

- Swift 5.0 ( Swift 4.2 -> use 'version 1.8.3' )
- iOS 9.1 (for use live photos)
TLPhotoPicker is available through CocoaPods. To install it, simply add the following line to your Podfile:
platform :ios, '9.1'

use delegate
You can choose delegate method or closure for handle picker event.
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 canSelectAsset(phAsset: PHAsset) -> Bool {
//Custom Rules & Display
//You can decide in which case the selection of the cell could be forbidden.
}
func didExceedMaximumNumberOfSelection(picker: TLPhotosPickerViewController) {
// exceed max selection
}
func handleNoAlbumPermissions(picker: TLPhotosPickerViewController) {
// handle denied albums permissions case
}
func handleNoCameraPermissions(picker: TLPhotosPickerViewController) {
// handle denied camera permissions case
}
}
use closure
init(withPHAssets: (([PHAsset]) -> Void)? = nil, didCancel: ((Void) -> Void)? = nil)
init(withTLPHAssets: (([TLPHAsset]) -> Void)? = nil, didCancel: ((Void) -> Void)? = nil)
var canSelectAsset: ((PHAsset) -> Bool)? = nil
var didExceedMaximumNumberOfSelection: ((TLPhotosPickerViewController) -> Void)? = nil
var handleNoAlbumPermissions: ((TLPhotosPickerViewController) -> Void)? = nil
var handleNoCameraPermissions: ((TLPhotosPickerViewController) -> Void)? = nil
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.handleNoAlbumPermissions = { [weak self] (picker) in
// handle denied albums permissions case
}
viewController.handleNoCameraPermissions = { [weak self] (picker) in
// handle denied camera permissions case
}
viewController.selectedAssets = self.selectedAssets
self.present(viewController, animated: true, completion: nil)
}
}
Custom Cell 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)
//Adding the possibility to handle cell display according to a specific conditions
func update(with phAsset: PHAsset)
func selectedCell()
func willDisplayCell()
func endDisplayingCell()
Custom Rules & Display
You can implement your own rules to handle the cell display. You can decide in which case the selection of the cell could be forbidden.
For example, if you want to disable the selection of a cell if its width is under 300, you can follow these steps:
- Override the update method of your custom cell and add your own display rule
override func update(with phAsset: PHAsset) {
super.update(with: phAsset)
self.sizeRequiredOverlayView?.isHidden = !(phAsset.pixelHeight <= 300 && phAsset.pixelWidth <= 300)
}
In this code, we show an overlay when the height and width required values are not satisified.
- When you instanciate a
TLPhotosPickerViewController
subclass, you can pass a closure calledcanSelectAsset
to handle the selection according to some rules. ( or delegate)
//use delegate
public protocol TLPhotosPickerViewControllerDelegate: class {
...
func canSelectAsset(phAsset: PHAsset) -> Bool
...
}
extension UserViewController: TLPhotosPickerViewControllerDelegate {
func canSelectAsset(phAsset: PHAsset) -> Bool {
if asset.pixelHeight < 100 || asset.pixelWidth < 100 {
self?.showUnsatisifiedSizeAlert(vc: viewController)
return false
}
return true
}
}
//or use closure
viewController.canSelectAsset = { [weak self] asset -> Bool in
if asset.pixelHeight < 100 || asset.pixelWidth < 100 {
self?.showUnsatisifiedSizeAlert(vc: viewController)
return false
}
return true
}
In this code, we show an alert when the condition in the closure are not satisfiied.
