iPad Vertical & Horizontal

Introduction

Step 1.

Make import.

#import <RXLayoutGallary/RXLayoutGallary.h>

Step 2.

Conform to protocols.

@interface RXViewController () <RXLayoutGallaryDelegate, NYTPhotosViewControllerDelegate, NYTPhotoViewerDataSource>
...
@end

Step 3.

Add these properties . They are needed for the correct operation of the framework, which opens photos in full screen mode.

@interface RXViewController () <RXLayoutGallaryDelegate, NYTPhotosViewControllerDelegate, NYTPhotoViewerDataSource>

@property (nonatomic, strong) NSMutableArray *imageForNYTPhotosVC;
@property (nonatomic, strong) NSNumber *numberOfPhotos;
@property (nonatomic, strong) UIImageView *touchedImgView;

@end

Step 4.

Initialize and add to superview the RXLayoutGallary is comfortable for you path. You have 3 option's.

1. Pass to RXLayoutGallary array with URLs
2. Pass to RXLayoutGallary array with UIImage or NSData (*nsdata only for gif images )
3. Pass to RXLayoutGallary array with UIImageView

// Init
RXLayoutGallary* gallaryURL = [[RXLayoutGallary alloc] initWithFrame:self.viewForURLGallary.bounds
andDelegate:self];

// Add to some superview
[self.viewForURLGallary addSubview:gallaryURL];

// Add pictures - Path by URL array
[gallaryURL addImageFromURL: self.urlImages];

OR

// Add pictures - Path by UIImage array
[gallaryLocalImages addUIImagesToGallary:self.localImages];

OR

// Add pictures - Path by UIImageViews array
[gallaryURL addUIImageViewsToGallary: self.localImages];

Step 5.

Implement the delegate method.

#pragma mark - GallaryViewDelegate

-(void)rxgallaryView:(RXLayoutGallary *)rxlayoutGallary didTapAtImageView:(UIImageView *)imageView atIndex:(NSUInteger)index{

    self.imageForNYTPhotosVC = [NSMutableArray new];;
    self.numberOfPhotos      = [NSNumber numberWithInteger:rxlayoutGallary.imagesArray.count];
    self.touchedImgView      = imageView;


    for (id imgFromGallary in rxlayoutGallary.imagesArray) {

        RXExamplePhoto *p = [RXExamplePhoto new];
        p.attributedCaptionTitle  = [RXViewController attributedTitleFromString:@"Chess"];
        p.attributedCaptionCredit = [RXViewController attributedCreditFromString:@"Photo: Chris Dzombak"];

        if ([imgFromGallary isMemberOfClass:[UIImageView class]])
        {
            UIImageView* imgView = (UIImageView*)imgFromGallary;
            [self.imageForNYTPhotosVC addObject:({
                p.image = imgView.image;
                p;
            })];
        }
        if ([imgFromGallary isMemberOfClass:[FLAnimatedImageView class]])
        {
            FLAnimatedImageView* flaImgView = (FLAnimatedImageView*)imgFromGallary;
            [self.imageForNYTPhotosVC addObject:({
                p.imageData = flaImgView.animatedImage.data;
                p;
            })];
        }
    }
    NYTPhotosViewController* vc = [[NYTPhotosViewController alloc] initWithDataSource:self
                                                                    initialPhotoIndex:index
                                                                             delegate:self];

    [self presentViewController:vc animated:YES completion:nil];
}

If you want, you can conform methods: They are need for most productive work with TableView. You should store in your controller or viewmodel cache property, then images will until upload from local cache.

-(NSData*) getDataFromCacheByURL:(NSString*) urlStr;
-(void) writeToCacheData:(NSData*) data urlKey:(NSString*) key;
-(NSOperationQueue*) getOperationQueue;

Step 6.

Implement the delegate methods.

#pragma mark - NYTPhotoViewerDataSource

- (NSInteger)indexOfPhoto:(id <NYTPhoto>)photo {
    return [self.imageForNYTPhotosVC indexOfObject:photo];
}

- (nullable id <NYTPhoto>)photoAtIndex:(NSInteger)photoIndex
{
    if (self.imageForNYTPhotosVC.count > photoIndex){
        return [self.imageForNYTPhotosVC objectAtIndex:photoIndex];
    }
    return  nil;
}

Step 7. - Optional

Implement the delegate and helpers methods .

#pragma mark - NYTPhotosViewControllerDelegate

- (UIView *)photosViewController:(NYTPhotosViewController *)photosViewController referenceViewForPhoto:(id <NYTPhoto>)photo {
    return self.touchedImgView;
}

#pragma mark - Helpers

+ (NSAttributedString *)attributedTitleFromString:(NSString *)caption {
    return [[NSAttributedString alloc] initWithString:caption
                                            attributes: @{NSForegroundColorAttributeName: [UIColor whiteColor],
                                                        NSFontAttributeName: [UIFont preferredFontForTextStyle:UIFontTextStyleBody]}];
}
+ (NSAttributedString *)attributedSummaryFromString:(NSString *)summary {
        return [[NSAttributedString alloc] initWithString:summary
                                               attributes:@{NSForegroundColorAttributeName: [UIColor lightGrayColor],
                                                NSFontAttributeName: [UIFont preferredFontForTextStyle:UIFontTextStyleBody]}];
}

+ (NSAttributedString *)attributedCreditFromString:(NSString *)credit {
        return [[NSAttributedString alloc] initWithString:credit
                                               attributes:@{NSForegroundColorAttributeName: [UIColor grayColor],
                                               NSFontAttributeName: [UIFont preferredFontForTextStyle:UIFontTextStyleCaption1]}];
}

Profit !!!!
