When I enter any value in the textfield of uiviewcontroller and get back using the navigation bar button item that value must be saved in the detailtextlabel of my previous tableviewcontroller.

Answer 1

Make property in appDelegate class

appDelegateview.h

    NSString *text;

    @property (nonatomic,retain) NSString *text;


AppDelegateview.h.m 

    @synthesize text

in viewWillDisappear of view.m

  yourAppDelegateClass *obj=(yourAppDelegateClass *)[[UIApplication sharedApplication] delegate];

  obj.text=@"your value";

in tableViewController.m


in cellForRowAtIndexPath:

yourAppDelegateClass *obj=(yourAppDelegateClass *)[[UIApplication sharedApplication] delegate];
cell.detailTextLabel.text=obj.text;
