How to insert new cell into UITableView in Swift

Question

I m working on a project where I have two UITableViews and two UITextFields  when the user presses the button the data in the first textField should go into the tableView and the second go into the second tableView  My problem is that I don t know how to put data in the tableView each time the user pushes the button  I know how to insert data with tableView cellForRowAtIndexPath  but that works for one time as far as I know  So what method can I use to update the tableView each time the user hits the button

Use beginUpdates and endUpdates to insert a new cell when the button clicked   As  vadian said in comment  begin endUpdates has no effect for a single insert delete move operation  First of all  append data in your tableview array Yourarray append  labeltext      Then update your table and insert a new row    Update Table Data tblname beginUpdates   tblname insertRowsAtIndexPaths   NSIndexPath forRow  Yourarray count-1  inSection  0    withRowAnimation   Automatic  tblname endUpdates    This inserts cell and doesn t need to reload the whole table but if you get any problem with this  you can also use tableview reloadData    Swift 3 0 tableView beginUpdates   tableView insertRows at   IndexPath row  yourArray count-1  section  0    with   automatic  tableView endUpdates     Objective-C  self tblname beginUpdates   NSArray  arr    NSArray arrayWithObject  NSIndexPath indexPathForRow Yourarray count-1 inSection 0     self tblname insertRowsAtIndexPaths arr withRowAnimation UITableViewRowAnimationAutomatic    self tblname endUpdates
