A snappy image viewer with zoom and interactive dismissal transition.

when i click on an image at a particular index in collection view that moment i want to download a high resolution image and pass that image in the imageviewer.

unitl the image downloads the screen gets stuck and doesn't present the image controller

I just installed simpleViewer as a pod. And I have confirmed that there is no closeButton image file. So I added a closebutoon file to my asset. I still get that message. Why?

Thank you for your great open source.

Can you provide an example to load the full image size in a block ? ie :

        let configuration = ImageViewerConfiguration { config in
            config.imageView = self.thumbnailImageView

            config.imageBlock = {
                        // What to put here ?
            }
        }

Thank you!

Expected behavior

Should have a linear animation when opening on iPhone X.

Actual behavior

After the end of the animation the image has a jerky effect

Steps to reproduce the behavior

Open any image with iPhone X

Expected behavior

When dragging an image from detail view the image can rotate (like in the Tweetbot iOS application) When swiping the image out of the screen, the user returns to the previous screen (image overview) When letting the image go, it restores to the image detail screen, with the correct orientation and the image centred in the screen.

Actual behavior

Image in detail view can be dragged but will stay oriented in the same orientation

Steps to reproduce the behavior

Check example in Tweetbot iOS application

When building our app in Xcode 10.3, it wouldn't compile because of a problem with ImageViewerController.xib in SimpleImageViewer. This was fixed by just opening and saving the xib using Xcode 10.3. I've also updated the build settings to Swift 5.

Fixes # . Newer cocoapods releases recommend specifying a swift_version parameter in podspec file. Changes proposed in this pull request:

• added said parameter

Expected behavior

When integrating this Pod into a Xcode project in swift 4.2, it should compile.

Actual behavior

It does not compile.

Steps to reproduce the behavior

Integrate this Pod into an Xcode project where the main target's swift_version is set to 4.2.

Podspec should just include the .swift_version parameter in podspec.

I just noticed, this pod doesn't take into account the UIKit renamings that occurred in swift 4.2.

In most modern apps some images showing as a circles. Animation of the transition in such case doesn't look nice. By adding new boolean flag to the configuration and slight change in transitions logic I made it possible to resolve this problem. Maybe it'll be useful for other developers too.

Expected behavior

The image view should shown in the center of the screen with close button properly in the top left corner

Actual behavior

The image view shows in the center of the screen and then snaps 10-20 points lower. Also the close button in the top left corner is in a weird place

Steps to reproduce the behavior

Tap on the image view that has simple image viewer set up

I use the following code in my project,

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
	let message = dataArray.object(at: indexPath.row) as! Message
	if message.ID == "904" {
		let cell = tableView.cellForRow(at: indexPath) as! ImageATableViewCell
		let configuration = ImageViewerConfiguration { config in
			config.imageView = cell.contentImage
		}
		present(ImageViewerController(configuration: configuration), animated: true)
	} else {
		let cell = tableView.cellForRow(at: indexPath) as!  ImageBTableViewCell
		let configuration = ImageViewerConfiguration { config in
			config.imageView = cell.contentImage
		}
		present(ImageViewerController(configuration: configuration), animated: true)
	}
}

When i click the row, it will work after around 1~10 second, The weird thing is when i one more tap the screen, function can immediately work, I also use the same image source test on UICollectionViewController, it's perfect work.

How can i fix that? thanks a lot :)

Expected behavior

No crash

Actual behavior

Crash

After showing the image I'm trying to change the background colour of the image view with transparent?

I tried to change the background colour on imageViewerController.xib and sets the imageViewerController.swift programatically. But I didn't get any changes in that behaviour still it appears black color background

Can you please help me on that?

Thanks in advance

Package Resolution Failed

SimpleImageViewer.git could not be resolved

because every version of SimpleImageViewer contains incompatible tools version and root depends on SimpleImageViewer 1.1.2..<2.0.0, version solving failed.

Fixes #.

Changes proposed in this pull request:

• Fix Image transaction while dragging, which caused a problem that hides some parts of the previous view in a specific ios versions from ios 13 to upper versions.

This is a long shot, but just in case anyone encountered the same issue: on iOS 13, dismissing an image will spark a different behavior on the presenting VC than dismissing by dragging the image far away.

It is not clear what exactly is or is not being called on the presenting VC. If that can help, it is a VC that shows a chat conversation using MessageKit, and the issue is that the input bar is not animating back into the view after dismissing the SimpleImage VC by dragging it. The bar does appear however when we close the image viewer by tapping the close button.

This issue also does not affect the app on iOS 12, so we suspect it might be linked to some of the VC lifecycle calls that are not been called anymore on iOS 13. But we also believe it shouldn't affect SimpleImageViewer, since the .overFullScreen modal presentation style is used, and this is not one of the iOS 13 affected styles.

If anyone has any idea on what we could try, we'd love to hear your ideas. Thanks!
