Answer 1

It seems you are not defining all your variables.
Check where value is defined and what its value is.
Also, perhaps you should first resign the responder of the text field and then reload the table view. Depending on your code, the text field whose first responder you resign might not exist any more after a table view reload.

Answer 2

enable zombie objects and it will tell you what error occured.
go to product>edit schems> enabl zombi objects

Answer 3

You are getting BAD_EXCESS in this line...
For more explanation post code of IntelligentPillBoxAppDelegate class
appdelegate.strip1_detail = [pillboxDb get_detail_for_din:value];
