    text
    copied!<p>In my app I have a folder-file (one-to-many relationship).So when I open my app, my firstViewController contains all files and when clicked on each folder, it opens a tableViewController displaying files in that folder.</p> <p>Now here whenever I swipe any row, it is moved to bottom row and the table is update accordingly, the next swiped row will go and sit above the first swiped row.</p> <p>Eg, at present if my table contains </p> <pre><code>0 1 2 3 A B C D </code></pre> <p>After swiping A</p> <pre><code>0 1 2 3 B C D **A** </code></pre> <p>after swiping B</p> <pre><code>0 1 2 3 C D **B A** </code></pre> <p>and so on, </p> <p>To do this functionality, I should update the NSOrderedSet also which is shown below</p> <pre><code>for (int i = 0; i &lt; [self.folder.file count]; i++) { File *file = [self.folder.file objectAtIndex:i]; if(file.completedStatus == false) { m_position = i; m_finalIndexPath = [NSIndexPath indexPathForRow:i inSection:0]; } } file.completedStatus = YES; id obj = [self.folder. file objectAtIndex:row]; NSMutableOrderedSet *files = [self.folder.file mutableCopy]; [files removeObjectAtIndex:row]; [files insertObject:obj atIndex:m_position]; NSIndexPath *currentIndexPath = [NSIndexPath indexPathForRow:row inSection:0]; [m_tableView moveRowAtIndexPath:currentIndexPath toIndexPath:m_finalIndexPath]; self.folder.file = files; } [self.managedObjectContext save:nil]; [m_tableView reloadData]; </code></pre> <p>This works fine in this View, and here self.folder, is particular folder on which the user clicks</p> <p>Now I have another ViewController called TestViewController where I have some of the file objects irrespective of in which ever folder they are present . I have populated the table of this TestViewController with these files, Now here also, when I swipe the cells, they will change the color but not move their position as above</p> <p>Eg </p> <pre><code>0 1 2 3 A C B D after swiping A and B 0 1 2 3 **A** C **B** D </code></pre> <p>Now here A can belong to folder 1 and B can belong to folder 2,</p> <p>when I close(dismiss) this TestViewController, What should happen is that</p> <p>a) it shows me the fileViewController by default b) the color of file A should change and it should move to a position by checking whether there are any swiped cells already. If yes, it should be placed above it or else at the bottom.</p> <p>c) similarly for color B.</p> <p>Regards Ranjit. </p>
