How To Use Storyboard?

Question

I'm trying to use storyboards segue instead of didSelectRowAtIndex.

This is what I have, but this method does not recognize indexPath.row. Is there an alternative I can use to do the same thing?

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{
    SpecificExerciseTableViewController *upcomingViewController = segue.destinationViewController;
    if ([segue.identifier isEqualToString:@"Web"]) 
    {
        upcomingViewController.exerciseArray = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"exercises"];
        upcomingViewController.muscleName = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"muscleName"];
    }
}

Answer 1

This trick works fine,heres an example of how I used it to pull parsed elements into a web view

.h file

@property (strong, nonatomic) NSString *url;
@property (strong, nonatomic) UIWebView *webView;

.m file

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
    if ([segue.identifier isEqualToString:@"WebViewSegue"]) {

        WebViewController *webViewController = segue.destinationViewController;
        webViewController.url = (self.parseResults)[indexPath.row][@"link"];
        webViewController.title = (self.parseResults)[indexPath.row][@"title"];

    }
}

Unless you have that indexPath as an ivar, no such variable exists in the scope.

If you would like to get the indexPath for the selected row in a UITableView use:

- (NSIndexPath *)indexPathForSelectedRow

The adjusted code for above:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];

    SpecificExerciseTableViewController *upcomingViewController = segue.destinationViewController;
    if ([segue.identifier isEqualToString:@"Web"]) 
    {
        upcomingViewController.exerciseArray = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"exercises"];
        upcomingViewController.muscleName = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"muscleName"];
    }
}
