Using 3D touch peek and pop with Longpress - objective-c

Question

I'm trying to emulate the 3D touch peek and pop for all devices (like Instagram) - so show the peek and pop at a longpress gesture. Is this possible? I found PeekView but so far I'm finding it impossible to incorporate this with my Objective C app (it's in Swift).
Currently I have replicated the PeekView Project - I have a collection view with a few cells and each cell has an image in it.
#property (nonatomic, strong) UILongPressGestureRecognizer *longPress;
- (PhotoCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
PhotoCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:kPhotoCell forIndexPath:indexPath];
cell.image.image = [UIImage imageNamed:#"image1"];
return cell;
}
- (void)collectionView:(UICollectionView *)collectionView willDisplayCell:(nonnull UICollectionViewCell *)cell forItemAtIndexPath:(nonnull NSIndexPath *)indexPath {
self.longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(handleLongPressGestures:)];
self.longPress.minimumPressDuration = 1.0f;
self.longPress.allowableMovement = 100.0f;
[cell addGestureRecognizer:self.longPress];
}
Now I'm trying to implement the handleLongPressGestures method but I can't use the PeekView methods due to the error shown below.
edit:
So when trying to use the viewForController method as shown in the example, if I add #objc, it complains about the Options part. Is there a workaround?
public enum PeekViewActionStyle : Int {
case Default
case Selected
case Destructive
}
public struct PeekViewAction {
var title: String
var style: PeekViewActionStyle
}
public class PeekView: UIView {
var shouldToggleHidingStatusBar = false
var contentView: UIView?
var buttonHolderView: UIView?
var completionHandler: (Int -> Void)?
var arrowImageView: UIImageView!
public class func viewForController(
parentViewController parentController: UIViewController,
contentViewController contentController: UIViewController,
expectedContentViewFrame frame: CGRect,
fromGesture gesture: UILongPressGestureRecognizer,
shouldHideStatusBar flag: Bool,
withOptions menuOptions: [PeekViewAction]?=nil,
completionHandler handler: (Int -> Void)?=nil) {
...

The problem with the library is that Swift struct cannot be bridged to Objective-C, so you cannot create the PeekViewAction array. I have updated the code with Obj-C support so now you can use another static method to show the PeekView. The usage is as below:
NSArray *options = #[#{#"Option 1": #(PeekViewActionStyleDefault)},
#{#"Option 2": #(PeekViewActionStyleDestructive)}];
UIViewController *contentViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"previewVC"];
[PeekView viewForControllerWithParentViewController:self
contentViewController:contentViewController
expectedContentViewFrame:CGRectMake(0, 0, 280, 400)
fromGesture:gesture
shouldHideStatusBar:YES
withOptions:options
completionHandler:nil];
Make sure you download the latest version of the library. Thanks for using PeekView and please report back if there's any other issue coming up :)
