DLFPhotosPicker: An Objective-C repository from nicnocquee

This is a library to select single photo or multiple photos in iOS 8 or later using iOS Photos framework. I use this library in my app, Delightful app.

Features:

Tap and hold a photo to preview (zoom).
Pinch out a photo to preview (zoom).
Drag to select multiple photos quickly. Simply drag to left or right to start selecting multiple photos.
Works on both landscape and portrait.
Using UISplitViewController for albums and photos. You can see the split view on iPhone 6 plus landscape.
Quickly clear all selections.
Selected photos are retained when changing album.

How to use

Use Cocoapods: pod 'DLFPhotosPicker' or copy all the files in DLFPhotosPicker/Classes folder to your project.
Present the DLFPhotosPickerViewController

DLFPhotosPickerViewController *picker = [[DLFPhotosPickerViewController alloc] init];
[picker setPhotosPickerDelegate:self];
[self presentViewController:picker animated:YES completion:nil];

Implement the delegate methods

#pragma mark - DLFPhotosPickerViewControllerDelegate

- (void)photosPickerDidCancel:(DLFPhotosPickerViewController *)photosPicker {
	[photosPicker dismissViewControllerAnimated:YES completion:nil];
}

- (void)photosPicker:(DLFPhotosPickerViewController *)photosPicker detailViewController:(DLFDetailViewController *)detailViewController didSelectPhotos:(NSArray *)photos {
	NSLog(@"selected %d photos", photos.count);
	[photosPicker dismissViewControllerAnimated:YES completion:nil];
}

- (void)photosPicker:(DLFPhotosPickerViewController *)photosPicker detailViewController:(DLFDetailViewController *)detailViewController configureCell:(DLFPhotoCell *)cell indexPath:(NSIndexPath *)indexPath asset:(PHAsset *)asset {
        // customize the cell based on index path and asset. For example, to mark if the asset has been uploaded.
    }

- (void)photosPicker:(DLFPhotosPickerViewController *)photosPicker detailViewController:(DLFDetailViewController *)detailViewController didSelectPhoto:(PHAsset *)photo {
[photosPicker dismissViewControllerAnimated:YES completion:^{
    [[PHImageManager defaultManager] requestImageForAsset:photo targetSize:PHImageManagerMaximumSize contentMode:PHImageContentModeDefault options:nil resultHandler:^(UIImage *result, NSDictionary *info) {
        NSLog(@"Selected one asset");

    }];
}];
}

You can check the SampleViewController class.

Properties

multipleSelections. Default: YES. Set this to NO to only select one photo. When this property is set to NO, delegate's photosPicker:detailViewController:didSelectPhoto: will be called. Implement that method to handle selected asset, then dismiss the photos picker.
