Question

I want to pass an “human” that was selected in a tableView to a detailViewController. I connected them in Interface Builder via Storyboards and set up an own segue identifier. The NSLog is called but it returns (null). Also, the in the detailView, nothing is shown but the default content…

My tableViewController:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{ 
if ([[segue identifier] isEqualToString:@"didSelectRow"]) {
    DetailViewController *detailViewController = (DetailViewController *)[segue destinationViewController];
    Human *employee = [[Human alloc] init];
    employee = [people objectAtIndex:[[self.tableView indexPathForSelectedRow] row]]; 
    [detailViewController setHuman:employee];

}
}

And the detailViewController

-(void)setHuman:(Human *)human
{
NSLog(@"%@",employee.name);
employee = human;
nameLab.text = employee.name;
descriptionLab.text = employee.description;
imageViewBig.image = [employee imageForName];
}

Thanks in advance!

Answer 1

Your variable human in setHuman contains employee. Thus you should assign the variable human to the @property human of the DetailViewController in your function. Or better still, just assign the property from outside: detailViewController.human = employee.

Your NSLog returns null because you call it before assigning human to employee.

Maybe choosing less repetitive ivar names would help.
