User · Answer

if you want to select some row this will help you

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[someTableView selectRowAtIndexPath:indexPath 
                           animated:NO 
                     scrollPosition:UITableViewScrollPositionNone];

This will also Highlighted the row. Then delegate

 [someTableView.delegate someTableView didSelectRowAtIndexPath:indexPath];

Use this category to select a table row and execute a given segue after a delay  Call this within your viewDidAppear method    tableViewController delayedSelection withSegueIdentifier      implementation UITableViewController  TLUtils   - void delayedSelection  NSIndexPath   idxPath withSegueIdentifier  NSString   segueID       if   idxPath  idxPath    NSIndexPath indexPathForRow 0 inSection 0                                                                                                                                                                         self performSelector  selector selectIndexPath   withObject     NSIndexPath   idxPath    UIStoryboardSegue   segueID   afterDelay 0                                                                                                     - void selectIndexPath  NSDictionary   args       NSIndexPath  idxPath   args   NSIndexPath                                                                                                                                                                                                  self tableView selectRowAtIndexPath idxPath animated NO scrollPosition UITableViewScrollPositionMiddle                                                                                                                                    if   self tableView delegate respondsToSelector  selector tableView didSelectRowAtIndexPath              self tableView delegate tableView self tableView didSelectRowAtIndexPath idxPath                                                                                                                                                       self performSegueWithIdentifier args   UIStoryboardSegue   sender self                                                                                                                                                                   end

UITableView s selectRowAtIndexPath animated scrollPosition  should do the trick   Just pass UITableViewScrollPositionNone for scrollPosition and the user won t see any movement     You should also be able to manually run the action    theTableView delegate tableView theTableView didSelectRowAtIndexPath indexPath    after you selectRowAtIndexPath animated scrollPosition  so the highlight happens as well as any associated logic

Like Jaanus told      Calling this  -selectRowAtIndexPath animated scrollPosition   method   does not cause the delegate to receive a   tableView willSelectRowAtIndexPath  or   tableView didSelectRowAtIndexPath  message  nor will it send   UITableViewSelectionDidChangeNotification notifications to observers    So you just have to call the delegate method yourself   For example   Swift 3 version   let indexPath   IndexPath row  0  section  0   self tableView selectRow at  indexPath  animated  false  scrollPosition  UITableViewScrollPosition none  self tableView self tableView  didSelectRowAt  indexPath    ObjectiveC version   NSIndexPath  indexPath    NSIndexPath indexPathForRow 0 inSection 0    self tableView selectRowAtIndexPath indexPath                              animated YES                        scrollPosition UITableViewScrollPositionNone    self tableView self tableView didSelectRowAtIndexPath indexPath     Swift 2 3 version    let indexPath   NSIndexPath forRow  0  inSection  0    self tableView selectRowAtIndexPath indexPath  animated  false  scrollPosition  UITableViewScrollPosition None   self tableView self tableView  didSelectRowAtIndexPath  indexPath

From reference documentation      Calling this method does not cause the delegate to receive a tableView willSelectRowAtIndexPath  or tableView didSelectRowAtIndexPath  message  nor does it send UITableViewSelectionDidChangeNotification notifications to observers    What I would do is   -  void tableView  UITableView   tableView didSelectRowAtIndexPath  NSIndexPath   indexPath        self doSomethingWithRowAtIndexPath indexPath       And then  from where you wanted to call selectRowAtIndexPath  you instead call doSomethingWithRowAtIndexPath  On top of that  you can additionally also call selectRowAtIndexPath if you want the UI feedback to happen

There are two different methods for iPad and iPhone platforms  so you need to implement both    selection handler and segue   NSIndexPath  indexPath    NSIndexPath indexPathForRow 0 inSection 0    self tableView selectRowAtIndexPath indexPath animated NO scrollPosition UITableViewScrollPositionNone       Selection handler  for horizontal iPad   self tableView self tableView didSelectRowAtIndexPath indexPath       Segue  for iPhone and vertical iPad   self performSegueWithIdentifier  showDetail  sender self
