Whatsapp for iOS has been updated to give users the ability to backup and restore via iCloud. The new update also includes a lot of other bug fixes.
If you’re to backup Whatsapp messages to iCloud, just navigate to Settings > Chat Settings > Chat Backup and then just set the frequency at which your backup should happen (Daily, Weekly or Monthly) and choose Backup Now.
This is the feature I’ve been waiting for, since I keep switching between my iPhone at work and at home. Now, hit the source link to Download Whatsapp from App Store.
The update also brings URL Schma support to Whatsapp, enabling third party developers to access or send data to Whatsapp directly from their apps.
