i have created a controller class named TAddAlarmController which has a tableview which consists of 6 rows .When i click on the second row it navigates to a page which is a new controller name TAlarmNewController which is a tableviewcontroller and in which i have created a nsmutablearray and populated that array with 7 static values so when the second controller is displayed the tableview is displayed with 7 static values in it.I want that when i click on any row of second controller the value that is present inside the cell of the paticular row should be set to detailtextlabel of the previouscontroller i.e TAddAlarmController .Please help me in solving this problem.this is my code:
this is AddAlarmcontroller.h
