In iOS 8 programs can interact so much closely, as never before. Besides possibility of data transfer (text, photo, file and so forth) through sharing menu, the system allows to open parts of programs in the interface of other programs. Now we can examine this innovative function on the example of system photoeditor.
There is a new button in editor of the Photo program in iOS 8 – a circle with ellipsis. Pressing this button opens a menu with a list of programs supporting pictures editing. Camera +, Afterlight and Fragment installed on my smartphone belong to the supported software. You can use tools of these programs for graphics processing without launching them, and then return to system Photo editor. It is very convenient.
