Change/Update current open photo caption

[VivekVithlani]

Hello,

I need to change the caption "description string" to a current open photo.

My scenario is, while user tap on edit caption then open alert controller with a text field, and user input caption of the current open photo caption and save it.

I try with reloadData(), and reloadInputViews() but not updated caption.

Note: I am not using custom caption view only pass a string in each caption.

Please let me know how to fix it.
