Select First Row as default in UITableView

Question

I have an application that is viewbased and I am adding a tableview as a subview to the main view. I have taken UITableViewDelegate to respond the table methods.

Answer 1

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.detailViewController = (DetailViewController *)[[self.splitViewController.viewControllers lastObject] topViewController];

    if([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){
        NSIndexPath* indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
        [self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionTop];
        [self tableView:self.tableView didSelectRowAtIndexPath:indexPath];
    }
}

Answer 2

- (void)viewWillAppear:(BOOL)animated
    {

       [super viewWillAppear:animated];

     // assuming you had the table view wired to IBOutlet myTableView

        // and that you wanted to select the first item in the first section

        [myTableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:0];
    }

Answer 3

Swit 3.0 updated Solution

let indexPath = IndexPath(row: 0, section: 0)
tblView.selectRow(at: indexPath, animated: true, scrollPosition: .bottom)

Answer 4

We use custom background images for the cell based on whether or not it is the first cell... a middle cell or the last cell. That way we get a nice rounded corner look to the whole table. When the row is selected, it swaps out a nice 'highlighted' cell to give the user feed back that they have selected a cell.

UIImage *rowBackground;
UIImage *selectionBackground;
NSInteger sectionRows = [tableView numberOfRowsInSection:[indexPath section]];
NSInteger row = [indexPath row];

if (row == 0 && row == sectionRows - 1)
{
    rowBackground = [UIImage imageNamed:@"topAndBottomRow.png"];
    selectionBackground = [UIImage imageNamed:@"topAndBottomRowSelected.png"];
}
else if (row == 0)
{
    rowBackground = [UIImage imageNamed:@"topRow.png"];
    selectionBackground = [UIImage imageNamed:@"topRowSelected.png"];
}
else if (row == sectionRows - 1)
{
    rowBackground = [UIImage imageNamed:@"bottomRow.png"];
    selectionBackground = [UIImage imageNamed:@"bottomRowSelected.png"];
}
else
{
    rowBackground = [UIImage imageNamed:@"middleRow.png"];
    selectionBackground = [UIImage imageNamed:@"middleRowSelected.png"];
}


((UIImageView *)cell.backgroundView).image = rowBackground;
((UIImageView *)cell.selectedBackgroundView).image = selectionBackground;

If you wish just make the first cell, that which is at indexPath.row == 0, to use a custom background.

This is derived from Matt Gallagher's excellent site

Swift 5.x Update:

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    let indexPath = IndexPath(row: 0, section: 0)
    tableView.selectRow(at: indexPath, animated: true, scrollPosition: .bottom)
    tableView.delegate?.tableView?(tableView, didSelectRowAt: indexPath)
}

This is working for me and hope this will helps you.

Happy Coding :)
