    <p>First off, I'd like to apologize in advance for not knowing this. I've been trying to get my head around the best way of dealing with memory management in this instance.</p> <p>I have a short method for determining if a file should be added to a list. One of the checks requires a NSFileManager be instantiated. Because some checks could potentially take a long time I want to jump out as soon as any of my conditions fail. However, if I return early my NSFileManager instance will never receive it's release message.</p> <p>I've thought about using an AutoReleasePool but since objects added to autoreleasepools don't get released until the end of the current run loop and my program looks over many thousands of files per run loop I don't like leaving them all allocated until the end of the loop.</p> <p>How can I ensure that each instance of my NSFileManager gets release appropriately. Any suggestions appreciated.</p> <p>Thanks!</p> <pre> - (BOOL) fileShouldBeAdded:(NSString *)filePath { BOOL fileShouldBeAdded = TRUE; NSFileManager *fileManager = [[NSFileManager alloc] init]; if ([[filePath lastPathComponent] containsString:@"test.txt"]) { fileShouldBeAdded = FALSE; return fileShouldBeAdded; } if (![fileManager xAttrFileAtPathShouldBeAdded:filePath]) { fileShouldBeAdded = FALSE; return fileShouldBeAdded; } if ([[BackupManager sharedInstance] isExcludedByUser:filePath]) { fileShouldBeAdded = FALSE; return fileShouldBeAdded; } if (![fileManager backupRequiredForPath:filePath]) { fileShouldBeAdded = FALSE; return fileShouldBeAdded; } [fileManager release]; return fileShouldBeAdded; } </pre>

    1. COYou're keeping the instance of FileManager in memory the entire time anyway, so it makes no difference whether you use an autoreleased instance or not. The autoreleased instance is really what you want here.

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.
