    <p>There are several places where this error could be arising. I would do the following to start searching for the problem:</p> <ol> <li>Search the project folder with finder and see if anywhere else the file "iContactsGridCell.h" exists. Or if any two files exist somewhere.</li> <li>Make sure that you don't have two Objects that are of Class iContactsGridCell that share the same name for example:</li> </ol> <p>iContactsGridCell *myObj; iContactsGridCell *myObj;</p> <ol> <li><p>Make sure your not doing anything like this: #import "iContactsGridCell <strong>.m</strong>"</p></li> <li><p>Or like this: #import "iContactsGridCell.h" #import "iContactsGridCell.h"</p></li> <li>Make sure your not re-declaring a class (including ones that Apple has provided in their frameworks)</li> </ol> <p><strong>Main Point:</strong> That's all I can think of off the top of my head. But the thing to remember is that somewhere in your project resides two objects, class declarations etc. That are the same. And the compiler is complaining because of it.</p> <p><strong>Why the Compiler would complain (more info):</strong> While this information is really "unnecessary" it's good practice as a programmer to understand what's going on under the hood and will often help debug, so here's a little info on compilers:</p> <p>Remember that a Compiler (while much more complex) is a program just like the ones that you create using it. One of the steps in most (if not all) compilers go through at one point or another reading code is creating "Symbols or Keys" for each variable, class, struct ect. So, at some point the compiler reached a line of code that "repeats / duplicates" somewhere else. So the "Key/Symbol" creation process done routine by the compiler fails.</p>

    1. COthank you for taking the time to answer. Unfortunately I have taken all the precautions you have suggested. Funnily enough, another class which also inherits from Cell, does not produce the same error. I think that the project has been somehow messed up, corrupted, etc.

    2. COwell, you lead me to the right place. I feel silly to say this, but the same class was both in the framework and the project. Once I removed it, problem solved. Kudos+++ If you would like to make an edit for redeclaration of a framework class, I will give you the answer :)

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.
