Why do I need variables? Because upon 2 different long presses in the cell, there are 2 images that need to be called in func contextMenuInteraction
Below is my code, where I assign a variable to each long press interaction. I get error Thread 1: Swift runtime failure: Unexpectedly found nil while implicitly unwrapping an Optional value
//In scope
var dd : UIInteraction!
var cc : UIInteraction!
@IBOutlet weak var immy: UIImageView!
//In override func awakeFromNib() and an objC long press function respectively
immy.addInteraction(dd) // (this is in the override nib)
self.like.addInteraction(self.cc) //(this is in the @objc func didLongPress())
Below is the func ContextMenuInteraction where the 2 interactions get called
func contextMenuInteraction(_ interaction: UIContextMenuInteraction, configurationForMenuAtLocation location: CGPoint) -> UIContextMenuConfiguration? {
UIContextMenuConfiguration(identifier: nil, previewProvider: {
if self.dd as! NSObject == interaction {
if let unwrappedImage = self.immy.image {
return ImagePreviewController(image:unwrappedImage)
}
else {
return nil
}
// put dd stuff here
} else if self.cc as! NSObject == interaction {
// put cc stuff here
let image3 = UIImage(named:"ring-309550-2.png")
if let unwrappedImage1 = image3 {
return ImagePreviewController(image:unwrappedImage1)
}
else {
return nil
}
}
else {
return nil
}
})
}
Where does the error unexpected found nil occur - In this line:
immy.addInteraction(dd)
Update this has been solved (not by me - someone on reddit)
// scope
var dd: UIContextMenuInteraction
var cc: UIContextMenuInteraction
// inside init()
self.dd = UIContextMenuInteraction(delegate: self)
self.cc = UIContextMenuInteraction(delegate: self)
// downstream
image1.addInteraction(dd)
image2.addinteraction(cc)
// inside contextMenuInteraction()
if self.dd == interaction {
...
} else if self.cc == interaction {
...
}
