How to apply your method if a collection with one visible image is installed on the screen. For example, when you increase the isolation and after you wind up the collection and stop at the 3 index, after you close the picture and on this day the collection would wind up to the desired index

@tungvoduc it's me again with the RTL :)

Could you please have a look on referencedViewForPhotoAt method with the RTL layout. It returns invalid index, Thanks again!

There is an issue here.

1. In landscape view on iPhone x, the image is pushed a few pixels to the right.
2. If you rotate the screen after zooming in, the position will not come out properly.

"In case you want to add more UI elements to each photo, the best way is to create a subclass of DTPhotoCollectionViewCell and then call either one of these methods registerClassPhotoViewer: or registerNibForPhotoViewer:"

Im using cocoapods, hence I cannot subclassed the DTPhotoCollectionViewCell, error above

It looks like the framework comes with SPM support (great!), but when I try to build there are numerous errors. I have several other libraries managed by SPM and they work without an issue...

I'm importing the library via Xcode 11's UI. Also fwiw I can build it just fine with Carthage.

How can i get the delegate response in UiViewController class? See my code here, I want to add cancel button on the top of the left corner. I am using BDFPostPhotoViewerController.swift file.

Here is my Image Tapped Function where i initialise the class, i want to show/hide cross button on corner when image zoom or zoom out.

i tried to use like this but here is some error. See screenshot

Please help me. Thanks

func photoViewerController(_ photoViewerController: DTPhotoViewerController, configurePhotoAt index: Int, withImageView imageView: UIImageView) {
    imageView.pin_setImage(from: images[index].link?.toURL, [placeholderImage:](url) cell.imageView.image)
    }
  }

when loading image i zoom imageView and when loaded image this is change zoomscale

My application crashes if I use the full size image in the following delegate:

func photoViewerController(_ photoViewerController: DTPhotoViewerController, configurePhotoAt 
index: Int, withImageView imageView: UIImageView) {
     imageView.image = images[index].image
}

But if I reduce the size of image, the problem is not there. It crashes after I scroll about 50 images. The console says that out of memory. So I think the application is out of memory when I am using heavy images.

I build a nice gallery UITableViewCell displaying a vary of Images using UIStackViews. This works fine and looks good...

But when I now want to show you PhotoViewerController I get some problems :(

That why you simple hide the referenceView. And when you do this, the UIStackView removes it and updates the constraints.

Any changes to change this to not hide the referenceView?

When integrating DTPhotoViewerConroller into a project using Swift Package Manager and Xcode 11 you get warnings about UIViewPropertyAnimator only being available in iOS 10+. Adding availability annotations fixes those errors and allows you to build the project.

I am trying to download from url's some photos and it seems that the referenceView is required.

Is there a way to have optional the referencedView? because sometimes referenceView is not always available (action from text to open a remote image for example)

(i have subclassed DTPhotoViewerController and added activityIndicator to hide when download completes)

I have copied your classes into my project. Some images are rotating/flipping automatically when I open them in DTPhotoViewer. Can you please help me to fix this issue? @tungvoduc

Hi, i've added this line: override var prefersStatusBarHidden: Bool { return true } in debug mode the setter is called, but the status isn't hidden. Is there another way to hide the status bar when the photo viewer is displayed?

Thank you

I wanted to update a label that I placed inside a custom DTPhotoViewerController everytime user swipes to reveal new photo. I stored the data to the image's identifier. How can I access the current presented image?

I tried self.imageView.image but it returns only the first image every time.

Edit: Yes I did try to follow the example but I wanted to hide/unhide this label (just like the close and save button from the example) along with other elements that I've placed.

I'd like to get notified when the viewer is dismissed interactively. Currently there's no way to get notified.

The reason I need it is I'm playing video in the photo viewer, and I want to stop it when the viewer is dismissed.

I'm subclassing DTPhotoViewController to add support for video, and I noticed that there's no method that exposes the currently visible collection view cell.

This is problematic for me because I need to access the cell in order to configure the AVPlayer instance I added to it. I can't do it in configureCell method because it's possible for a user to scroll a bit and then give up (thus returning to the previous cell), but other methods don't pass in the cell instance.

I suppose I can cast scrollView to UICollectionView and use that, but that's not future-proof. Can we have a way to access the current cell?

Thank you!
