# DO NOT USE. "I AM SUPER DUPER CEREAL, YOU GUYS."

### ~~*This repository is no longer under active development. I think it's probably still safe to use on iOS 7 through 9, but your mileage may vary. I may someday do a thorough rewrite in Swift, taking into account newer API features, etc. ~ Jared*~~

JTSImageViewController

======================

An interactive iOS image viewer that does it all: double tap to zoom, flick to dismiss, et cetera.

## Pull Requests

Pull requests are welcome, but should be submitted on the `dev` branch. Exceptions will be made for critical bug fixes.

## What Does it Do?

JTSImageViewController is like a "light box" for iOS. It's similar to image viewers you may have seen in apps like Twitter, Tweetbot, and others. It presents an image in a full-screen interactive view. Users can pan and zoom, and use Tweetbot-style dynamic gestures to dismiss it with a fun flick.

## How Does it Work?

Usage is pretty simple, though there are some cool options and delegate methods if you need them. Here's what your simplest implementation might look like:

```objc

- (void)someBigImageButtonTapped:(id)sender {

    

    // Create image info

    JTSImageInfo *imageInfo = [[JTSImageInfo alloc] init];

    imageInfo.image = YOUR_SOURCE_IMAGE;

    imageInfo.referenceRect = self.bigImageButton.frame;

    imageInfo.referenceView = self.bigImageButton.superview;

    

    // Setup view controller

    JTSImageViewController *imageViewer = [[JTSImageViewController alloc]

                                           initWithImageInfo:imageInfo

                                           mode:JTSImageViewControllerMode_Image

                                           backgroundStyle:JTSImageViewControllerBackgroundOption_Scaled];

    

    // Present the view controller.

    [imageViewer showFromViewController:self transition:JTSImageViewControllerTransition_FromOriginalPosition];

}

```

That's it.

## Extras and Options

- **Image Downloads:** If you don't have the source image already, just use the `imageURL` property when setting up the `JTSImageInfo` instance. JTSImageViewController will handle downloading the image for you.

- **Background Styles:** Choose between a scaled-and-dimmed style or a scaled-dimmed-and-blurred background style. The latter is like the one used in Tweetbot.

- **Alt-Text Mode:** Need to show the alt text for an image? JTSImageViewController includes an alternate mode that shows a full-screen, centered text view using the same style as the image mode.

- **Handle Long-Presses:** Implement an `interactionsDelegate` to respond to long presses on the image, or to temporarily disable user interactions (comes in handy if you show an overlay that could cause gesture conflict).
