iOS users express dissatisfaction with the restricted inter-app sharing capabilities. When viewing a document, photo, or website, you will see a "share" option, however this is normally limited to system and partner applications. under the significant iOS 8 release, Apple added the so-called "Share extensions" — a new element of the app sandbox that allows developers to include their own applications under the "Share with..." menu, but most have yet to do so.
For example, Instagram certainly took its sweet time. However, iPhone users will be pleased to learn that after installing the new update, they will be able to send photographs to Instagram directly from the Photos app. Just open up your gallery, tap on “Share with...” and find Instagram. Previously, you could only post photographs to Instagram directly from the proprietary app, which is inconvenient if you prefer to browse with the default photographs app.
