    <p>Alright so I am a little new to the NSMutableArray class and I think I am missing something obvious. I have an object pass a NSMutable Array to my window controller like so in my.m:</p> <pre><code>summaryWindow = [[SummaryWindowController alloc] init]; [summaryWindow setGlobalStatusArray:globalStatusArray]; </code></pre> <p>I have the receiver method in the summaryWindow object as so:</p> <pre><code>-(void)setGlobalStatusArray:(NSMutableArray *)myArray { if ([myArray count] &gt;0) { if (globalStatusArray) { [globalStatusArray release]; } globalStatusArray = [[NSMutableArray alloc] initWithArray:myArray]; NSLog(@"Summary Window Init with new array: %@",globalStatusArray); </code></pre> <p>I see the NSLog no problem, and in that same object (summaryWindow) I have the following method:</p> <pre><code>- (NSMutableArray *)getGlobalStatusArray { return globalStatusArray; } </code></pre> <p>Now I have globalStatusArray declared in my .h file as</p> <pre><code>NSMutableArray *globalStatusArray; </code></pre> <p>So shouldn't This be retained because I am using: initWithArray?</p> <p>When I try to access this value in an another IBAction method:</p> <pre><code>- (IBAction)refreshButtonClicked:(id)sender { NSLog(@"The user has clicked the update button"); [ aBuffer addObjectsFromArray: globalStatusArray]; NSLog(@"Buffer is currently:%@",aBuffer); [tableView reloadData]; } </code></pre> <p>The NSMutable array is null</p> <pre><code>2011-08-18 10:40:35.599 App Name[65677:1307] The user has clicked the update button 2011-08-18 10:40:35.600 App Name[65677:1307] Buffer is currently:( ) </code></pre> <p>I have tried using my own method to get the value i.e. [ self getGlobalStatusArray] to but I am missing something huge. FYI aBuffer is also declared in my .h ,</p>

    1. CORather than `nil`, it looks like your array is empty. If it was `nil`, it would log `(null)`

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.
