UITableView doesn't keep row selected upon return

Question

i have several table views in my app. I am familiar with the usual behaviour of tables, that when you select a row and progress to a pushed view, it turnes blue, then when y

Answer 1

apparently viewWillAppear: of the class UITableView does deselect all cells, even without reloading the cells. The trick described worked for me:

code from my UITablViewController:

- (void)viewWillAppear:(BOOL)animated
{
    NSIndexPath *selectedIndex = [self.tableView indexPathForSelectedRow];

    [super viewWillAppear:animated];

    //Re select cell
    [self.tableView selectRowAtIndexPath:selectedIndex animated:NO scrollPosition:UITableViewScrollPositionNone];
};

Answer 2

NSIndexPath *_selectedIndex ;

use the above global variable to store in selected in the table view delegate method

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
 _selectedIndex = [self.tableView indexPathForSelectedRow];
}

and in the following delegate of UINavigationController delegate method

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[self.tableView selectRowAtIndexPath:_selectedIndex animated:NO scrollPosition:UITableViewScrollPositionNone];

}

Answer 3

Use this piece of code in the end of didSelectRowAtIndexPath delegate method of table view,

[tableView deselectRowAtIndexPath:indexPath animated:NO];

Answer 4

Try

[tableView deselectRowAtIndexPath:indexPath animated:NO];

for deselecting a row and

[tableView selectRowAtIndexPath:indexPath animated:NO];

for highlighting the selected row.

Answer 5

Its a feature you can turn off.

In the UITableViewController you can call

[ self setClearsSelectionOnViewWillAppear:NO ];

This is directly from the file "UITableViewController.h". This feature is documented there.

   @property(nonatomic) BOOL clearsSelectionOnViewWillAppear __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_3_2); 
// defaults to YES. If YES, any selection is cleared in viewWillAppear:

Answer 6

I am not sure if this is relevant but there is a flag in UITableViewController I just noticed called

@property(nonatomic) BOOL clearsSelectionOnViewWillAppear NS_AVAILABLE_IOS(3_2); // defaults to YES. If YES, any selection is cleared in viewWillAppear:

I think this should solve some of the problems people are describing here.
