    <p>I have been trying to find out the problem to this for a day now, and can't seem to find the fix. </p> <pre><code>int person; -(IBAction)personOne:(id)sender{ [twoPerson stopAnimating]; [fourPerson stopAnimating]; [threePerson stopAnimating]; [onePerson startAnimating]; person = 1; } -(IBAction)personTwo:(id)sender{ [threePerson stopAnimating]; [fourPerson stopAnimating]; [onePerson startAnimating]; [twoPerson startAnimating]; person = 2; } -(IBAction)personThree:(id)sender{ [fourPerson stopAnimating]; [onePerson startAnimating]; [twoPerson startAnimating]; [threePerson startAnimating]; person = 3; } -(IBAction)personFour:(id)sender{ [onePerson startAnimating]; [twoPerson startAnimating]; [threePerson startAnimating]; [fourPerson startAnimating]; person = 4; } </code></pre> <p>What I'm trying to do is if this button is clicked then Person is equal to an integer value. </p> <p>I don't see a problem with this code at all. </p> <p>I then have another button that's using if statements.</p> <pre><code>-(IBAction)go:(id)sender{ ammountDueFloat = ([ammountDue.text floatValue]); tipPercent1; findAmmount = tipPercent1 * ammountDueFloat; NSString *showAmmountText = [[NSString alloc]initWithFormat:@"$%.2f", findAmmount]; showammount.text = showAmmountText; if (person = 1) { showPerPerson = findAmmount / 1; perPersonLabel.text = [[NSString alloc]initWithFormat:@"$%.2f", showPerPerson]; } if (person = 2) { showPerPerson = findAmmount / 2; perPersonLabel.text = [[NSString alloc]initWithFormat:@"$%.2f", showPerPerson]; } if (person = 3) { showPerPerson = findAmmount / 3; perPersonLabel.text = [[NSString alloc]initWithFormat:@"$%.2f", showPerPerson]; } if (person = 4) { showPerPerson = findAmmount / 4; perPersonLabel.text = [[NSString alloc]initWithFormat:@"$%.2f", showPerPerson]; } else { showPerPerson = findAmmount / 1; perPersonLabel.text = [[NSString alloc]initWithFormat:@"$%.2f", showPerPerson]; } } </code></pre> <p>Whenever I click the button 'go' it always assumes the value of person is the last if statement. </p> <p>Any ideas?</p>

    1. COXcode4 gives you a warning when you use '=' operator in a if() condition. You should heed the warnings.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
