I have 4 text fields. by default, keypad cursor is on the first text field. when the user enters any key, entered text will show on first field and cursor will go on the second screen. Now the user is taping on keypad back button. now cursor will be on the first field but any delegate methods are not calling when the user tapped on keypad back button. – Vikash Dummy Apr 24 '17 at 12:27

I think you need to add a custom back button and define its action.
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton setFrame:CGRectMake(0,0,30,30)];
backButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
[backButton addTarget:self action:@selector(backBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barBackButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
navitem.hidesBackButton = YES;
navitem.leftBarButtonItems = @[barBackButtonItem];
