I am new in ios and I am facing problem regarding to UISearchbar. I have done code like this
.h

recipes = [NSArray arrayWithObjects:#"Egg Benedict", #"Mushroom Risotto", #"Full Breakfast", #"Hamburger", #"Ham and Egg Sandwich", #"Creme Brelee", #"White Chocolate Donut", #"Starbucks Coffee", #"Vegetable Curry", #"Instant Noodle with Egg", #"Noodle with BBQ Pork", #"Japanese Noodle with Pork", #"Green Tea", #"Thai Shrimp Cake", #"Angry Birds Cake", #"Ham and Cheese Panini", nil];

}

}

cell.textLabel.text = [searchResults objectAtIndex:indexPath.row];
} else {

}
return cell;
}

{

}
But it shows me search bar on navigation bar
But I need to show it on the UItableView itself. Like this in Image
Thanks in advance

You should remove
[myTableView selectRowAtIndexPath:0 animated:YES scrollPosition:
UITableViewScrollPositionNone];
and use this to select the first row (this should be called once outside this method or you want to set this row selected everytime each cell is render)
[myTableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionNone];
And I don't know why you called this in this method
[myTableView.delegate tableView:myTableView didSelectRowAtIndexPath:0];
but if you want to call it you should change to this too
[myTableView.delegate tableView:myTableView didSelectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
ps. You should set the cell's selectionStyle correctly to see the cell is selected.
Update::
Try to replace all codes in the method with this
Report_SelectGroupTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Report_SelectGroupTableViewCell"];
if (!cell){
cell = [[[NSBundle mainBundle] loadNibNamed:#"Report_SelectGroupTableViewCell" owner:self options:nil] objectAtIndex:0];
}
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
[tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionNone];
return cell;
Please tell me if the first row is not selected and highlighted.
I have a tableview that displays a list of "favorited" items. Users favorite items in another tableview, and favorited items are listed in this tableview (FavoritesTableView.m).

In your .h take one NSMutableDictionary and do property to it.
In your .m synthesize it,and in viewdidLoad alloc the Dictionary.
Now put this below code in CellForRowAtIndex
if([idDictonary objectForKey:[NSString stringWithFormat:#"%d",[indexPath row]]])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
and put this below code in DidSelectRowAtIndex
UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
if (thisCell.accessoryType == UITableViewCellAccessoryNone)
{
thisCell.accessoryType = UITableViewCellAccessoryCheckmark;
[idDictonary setValue:[dataArray objectAtIndex:indexPath.row] forKey:[NSString stringWithFormat:#"%d",[indexPath row]]];
}
else
{
if([idDictonary objectForKey:[NSString stringWithFormat:#"%d",[indexPath row]]])
{
[idDictonary removeObjectForKey:[NSString stringWithFormat:#"%d",[indexPath row]]];
thisCell.accessoryType = UITableViewCellAccessoryNone;
}
}
[myTableView reloadData];

i hope this will helps u Brittany...
Every time -tableView:cellForRowAtIndexPath: runs, you create a new button, set it to the desired properties and … throw it away. (Seems to be the running joke this week.) You have to use the existing button.
I am making a small app. And having a trouble right now. Trouble by deleting a table customized cell.
it keep removing the top cell instead of the right selected cell. I delete cell number 20, it still delete the cell number 1. I don't know why. please help me out. Really appreciate.

The only objects you should be releasing or setting to nil in viewDidUnload are like buttons, labels, textBoxes etc.
When you do self.selectedSession = nil, for example, it is calling the release for that method; that is the point of properties, they handle the allocs and releases.
You posted a tableView:didSelectRowAtIndexPath:, but I don't think you told us which class that was in.
In any case, that method seems to have a bug:
selectedSession = (Session *)[__fetchedResultsController objectAtIndexPath:indexPath];
sessionViewController.selectedSession = self.selectedSession;
I think on the first line, you meant to say self.selectedSession, assuming you go on to release selectedSession in this class' dealloc. (This may not be your only issue)
EDIT:
You should set properties to nil in viewDidUnload if and only if those properties were set as a result of the loading of the view from your nib, or were set in loadView, or in viewDidLoad. The reason you're doing this is because viewDidLoad or loadView may be called more than once during the lifetime of the view controller.
EDIT:
Check that you are using the property when setting fetchedResultsController and make sure you aren't setting that to nil on viewDidUnload.
Dont set selectedSession and exerciseArray to nil in viewDidUnload.
Since you're doing that, it will crash in the dealloc as you're trying to release nil objects.
Also, before you release arrays, it's always a good idea to call [array removeAllObjects].
in your viewDidLoad method you are setting self.selectedSession and self.exerciseArray to nil. You should only set interface outlets to nil in viewDidLoad. But this isn't the cause of your crash because by the time you get to dealloc, you are just sending release to nil.
you might want to look into the contents of the selectedSession Object. you might be over releasing an NSString in one of it's members
