Image duplication in iOS 13b3 [BUG] about uiimageviewalignedswift HOT 10 CLOSED

Im not sure if its a bug, I would have thought that setting the layers contents to nil should in theory remove the image however setting the layers contents to a CALayer works fine. e.g.

if #available(iOS 13, *) {
   self.layer.contents = CALayer()
} else if #available(iOS 11, *) {
   super.image = nil
} else {
   layer.contents = nil
}

from uiimageviewalignedswift.

Fixed removing
if #available(iOS 11, *) { super.image = nil }

everywhere (didMoveToSuperview,didMoveToWindow,updatelayout, etc)

This fix also for iOS11.

You need only to invalidate layer:
layer.contents = nil

Instead of complaining, try to fix it yourself ;)

I tried, it didn’t work. I don’t have one problem, please solve this problem as soon as possible.

@yuriandryu I forked the repo, then replaced the superclass to UIView. Removed the override-s and the calls for super.image and basically fixed the errors in the class. Yes, I lost the ability to attach Kingfisher to that UIImageView, or the RxCocoa .rx.image property, but still, it works now.

I respect. did as you said, everything works now! Thanks bro

Rather than remove kf etc UIImageView support I worked around this by ensuring the super image wasn't one that can be seen.
So I updated updateLayout to set the super image to a transparent image like so; works fine for now.

if #available(iOS 11, *) { super.image = UIImage(named: "transparent_image") }

@neilkachu Tried your solution unsuccessfully 😢. Is transparent_image just a place holder, or it is an actual existing transparent image? this is suppose to replace the = nil.

@neilkachu Your solution doesn't work for me unfortunately. I have a transparent asset but still double images.

Yes, just a 1px transparent image in the Assets lib so not sure why it's not working your end, that was the only change I ended up with.,
@christoff-1992 's solution looks cleaner, I'd re-try with that.
