Select the newly added dynamic row in UITableView - ios

Question

I am working with a MasterDetail View using SplitViewController in iPad, My Master View has a tableView where I add rows dynamically. So the newly added row sits at zero postion. So what I want to achieve is that, I want to select the newly added row as soon as it is added to the Master table. Later when the user adds a new row, that row should be selected and the previously added row should be deselected.
For this I have written the code below
- (void)selectNewlyAddedRow
{
NSIndexPath* selectedCellIndexPath= [NSIndexPath indexPathForRow:0 inSection:0];
[m_tableView selectRowAtIndexPath:selectedCellIndexPath animated:TRUE scrollPosition:UITableViewScrollPositionNone];
[self tableView:m_tableView didSelectRowAtIndexPath:selectedCellIndexPath];
}
This code works if I write it in function ViewDidAppear, but if I write it in cellForRowAtIndexPath it doesnt work..
Please provide me correct understanding where I am going wrong.

Answer 1

viewDidAppear wont get call when you add new row so you just register for table reloaded notification and in method for that notification call select first row I hope it will help you....
- (void)selectFirstRow{
if ([self.tableView numberOfSections] > 0 && [self.tableView numberOfRowsInSection:0] > 0) {
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionTop];
[self tableView:self.tableView didSelectRowAtIndexPath:indexPath];
}
}

Implement this delegate -
-(void)tableView:(UITableView )tableView didEndDisplayingCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath)indexPath{
[NSNotificationCenter defaultCenter];
[notificationCenter postNotificationName:#"Table Reloaded" object:nil];
}
In your view controller add this line in viewdidload
-(void)viewDidLoad{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(tableReloaded:) name:#"Table Reloaded" object:nil];
}
-(void) tableReloaded:(NSNotification*)notification{
[self selectFirstRow];
}
