They are many months waiting for an update like this, and although it is not yet available officially, and only those who have installed WhatsApp Beta for iOS can use this feature, the fact that it is already activated in the last Beta, along with the video call, suggests that the next update WhatsApp for iOS may finally include send animated images (GIFs) without having to resort to tricks Jailbreak or anything like that. We explain in the video how can be done in detail.
This feature is present since long ago in the Betas of WhatsApp, but disabled by default but can be used unless you modificaras the application code. It seems that WhatsApp development team already has the feature to point and already seems in the latest available Beta. How can I send a GIF from your iPhone? It will be a fairly simple process, and you can even use other GIF different sources which brings the application itself.
Send a GIF using the function integrated in the app

It will be as simple as sending a photo from the reel. Click on the camera icon to share a photo as we usually do, access the spool and we look down on the left, where it appears a small magnifying glass along with the GIF text. There will access to the library GIF, can perform a search or select those GIFs that have kept as featured to have them always hand. Then we will be shown a screen of Edition where can modify the file if want, and by pressing in send will arrive to our recipient.
Send a GIF using another source

But we can not only send GIF within the integrated in WhatsApp, search engine really any link to a GIF will be detected as such and can send it without the slightest problem. If we use a keyboard that incorporates a search of GIF, as GBoard, the keyboard of Google, can comfortably perform searches and paste them images animated in our conversation.
Next update: GIF and video calls
WhatsApp already has available video calls and GIFs in the latest Beta for iOS flush several versions with this hidden function in your code. When will it be available? Because it logical would be that in the next update official these functions already were fully functional for all, but never is knows what can decide to last time. We will keep you informed.
