GifView | Gif image custom display

This code is not tested, I'm just following the document you posted. Seems like you don't need to check if countdownLabel.isFinished(), because there is a delegate method for that which will be called as soon as it is finished.

Set up the delegate in func setupCountdown():

As mentioned in comments, you seem to be instantiating the popup controller 2 times, so try it like this in your showPopOver code:

Make use of Glide and get gifs from assets like this:

You need to do

sudo apt-get install autoconf

Before you run npm install as that seems to be an error in autoconf in linux.

In your file one.GIF, the extension is all uppercase. However, you can see in the source code that it's looking for lowercase .gif.

You need to rename one.GIF to one.gif.

From Getting References to Bundle Resources: The Bundle Search Pattern:

Important: The bundle interfaces consider case when searching for resource files in the bundle directory. This case-sensitive search occurs even on file systems (such as HFS+) that are not case sensitive when it comes to file names.

OK this is a very silly error. The solution deploys fine and works on an Android phone. I guess the Design feature of Visual Studio is bugged and is displaying an incorrect error.

Tried to recreate your project with provided code and everything worked as expected until I noticed that your image view is constrained to cell content view margins. Then it started to throw those layout errors and the cells became unreasonably high. So my guess is that you need to make sure your image view constraints are not relative to cell margins.

Also make sure that you do not have heightForRowAt override in your view controller.

To completely get rid of the autolayout errors you can set the bottom constraint priority to 999 (blog post with explanation about why priority helps)

I would recommend you to go through the library before you start using them. You're using ImageView instead of GifImageView in your code.

Rather then using the default ImageView you should be using GifImageView provided by the library as mentioned in sample example here.

You can try this , it would be a matter of milli seconds [ depending in validation time ] even if you add the subview out of the if statement , but it will prevent any user event
