pass data from selected row to view controller - ios

Question

I have a UITableView in a popover. When a user selects a row in the popover I am wanting it to close the popover and save some data in the cell to a variable in the parent view controller. What is the most efficient way to do this?

Answer 1

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
In this method you handle the user selection. For passing variables between view controllers from a UITableView to another ViewController read this great tutorial from ray wenderlich : http://www.raywenderlich.com/1797/how-to-create-a-simple-iphone-app-tutorial-part-1

Answer 2

Create a delegate in popover's table view controller and pass the variable to it as cell data
In .h of the popover's table view controller
#protocol PopoverTableViewControllerDelegate <NSObject>
- (void)didSelectRow:(NSString *)cellDataString;
#end
#interface PopoverTableViewController : UITableViewController
#property (strong, nonatomic) id<PopoverTableViewControllerDelegate> delegate;
#end
In the .m's didSelectRowAtIndexPath call the delegate and pass the cell data variable as
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.delegate didSelectRow:cellDataString];
}
- (void)dealloc
{
[super dealloc];
[_delegate release];
}
Implement it in parent view controller in .h implement the PopoverTableViewControllerDelegate as
#interface ParentViewController : UIViewController <PopoverTableViewControllerDelegate>
#property (strong, nonatomic) NSString *cellDataString;
#end
and in .m implement the delegate as
- (void)dealloc
{
[super dealloc];
[_cellDataString release];
}
PopoverTableViewController *popoverTableViewController = [[[PopoverTableViewController alloc] init] autorelease];
popoverTableViewController.delegate = self;
- (void)didSelectRow:(NSString *)cellDataString
{
self.cellDataString = cellDataString;
[popOverController dismissPopoverAnimated:YES];
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ParentViewController *parent = [[ParentViewController alloc] initWithNibName:#"ParentViewController" bundle:nil];
parent.variable = //do something you want
[self.navigationcontroller pushViewController:parent animated:YES];
}
Something like this... Hope this helps...
