    <p>This question is based off of the same app/source from my previous question which can be found here:</p> <p><a href="https://stackoverflow.com/questions/4552783/how-to-manage-memory-using-classes-in-objective-c">How to manage memory using classes in Objective-C?</a></p> <p>I have a nested array which looks something like this when printed out (I only copied and pasted a brief part of it).</p> <pre><code>( ( &lt;Term: 0x4256420&gt;, &lt;Term: 0x420fa40&gt;, &lt;Term: 0x4257bd0&gt;, &lt;Term: 0x4257cf0&gt;, &lt;Term: 0x4257d90&gt;, &lt;Term: 0x4257e30&gt; ), ( &lt;Term: 0x4257e50&gt;, &lt;Term: 0x4257f90&gt;, &lt;Term: 0x4257fb0&gt;, &lt;Term: 0x42580e0&gt;, &lt;Term: 0x4258170&gt;, &lt;Term: 0x4258210&gt;, &lt;Term: 0x4258230&gt;, &lt;Term: 0x4258360&gt;, &lt;Term: 0x4258400&gt;, &lt;Term: 0x42584a0&gt;, &lt;Term: 0x4258540&gt;, &lt;Term: 0x42585e0&gt;, &lt;Term: 0x4258670&gt;, &lt;Term: 0x4258710&gt; ), </code></pre> <p>And here is my code for the search part of my table:</p> <pre><code>- (NSInteger)tableView:(UITableView *)aTableView numberOfRowsInSection:(NSInteger)section { // Normal table if (aTableView == self.tableView) return [[self.sectionArray objectAtIndex:section] count]; // Search table //NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name contains[cd] %@", self.searchBar.text]; //self.filteredArray = [self.crayonColors filteredArrayUsingPredicate:predicate]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name contains[cd] %@", self.searchBar.text]; self.filteredArray = [[self.sectionArray objectAtIndex:section] filteredArrayUsingPredicate:predicate]; return self.filteredArray.count; } </code></pre> <p>I am getting the error that I cannot allocate enough room which means that I must be doing something wrong, I just cannot figure out what.</p> <p>The commented out portion of the search part in the above method works but crayonColors is just a simple NSMutableDictionary of NSStrings and does not have arrays nested inside of it.</p> <p>Thanks in advance!</p>

    1. COPresumably, a `Term` object has a `name` property. My question is "what are you trying to achieve?" You have an array of arrays of objects, but what are you trying to get out of it? (ie, what objects are you wanting to end up with?)

    2. COSo sectionArray has that nested array of Term objects. Using NSPredicate I am trying to search for whatever the person typed in the search bar. So that means like if they type in 'A' I want whatever contains an 'A' in it. I am trying to get those Term objects into the filteredArray.

    3. CObut do you want them in a single array, or do you want an array of filtered arrays? Or something else?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
