    <p>I want to delete a cell in one of my 2 tableViews (1 is the main one, 2 the Favorites one).</p> <p>To delete a cell, i should set a specific value to "NO", in order to be NO in the plist (the Favorite table shows only cells with "isFav" value set to YES). </p> <p>Check this question for further details: <a href="https://stackoverflow.com/questions/11157692/uitableview-not-showing-the-right-cells">UITableView not showing the right cells</a></p> <p>Back to my question, i tried to do</p> <pre><code>- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { NSArray *plist = [self readPlist]; NSMutableDictionary *theItem = [[[plist objectAtIndex:indexPath.section] valueForKey:@"Rows"] objectAtIndex:indexPath.row]; NSLog(@"%@",theItem); if (editingStyle == UITableViewCellEditingStyleDelete) { [theItem setValue:[NSNumber numberWithBool:NO] forKey:@"isFav"]; [self.tableView deleteRowsAtIndexPaths:[[[NSArray arrayWithObject:[plist objectAtIndex:indexPath.section]]valueForKey:@"Rows"]objectAtIndex:indexPath.row] withRowAnimation:UITableViewRowAnimationNone]; [self writePlist:plist]; [self.tableView reloadData]; } } - (void)writePlist:(NSArray*)arr { NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *plistPath = [[documentPaths lastObject] stringByAppendingPathComponent:@"tipsList.plist"]; NSFileManager *fMgr = [NSFileManager defaultManager]; if ([fMgr fileExistsAtPath:plistPath]) [fMgr removeItemAtPath:plistPath error:nil]; [arr writeToFile:plistPath atomically:YES]; } - (NSArray*)readPlist { NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *plistPath = [[documentPaths lastObject] stringByAppendingPathComponent:@"tipsList.plist"]; NSFileManager *fMgr = [NSFileManager defaultManager]; if (![fMgr fileExistsAtPath:plistPath]) { plistPath = [[NSBundle mainBundle] pathForResource:@"tipsList" ofType:@"plist"]; } NSMutableArray *returnArr = [NSMutableArray arrayWithContentsOfFile:plistPath]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"isFav == YES"]; for (NSDictionary *sect in returnArr) { NSArray *arr = [sect objectForKey:@"Rows"]; [sect setValue:[arr filteredArrayUsingPredicate:predicate] forKey:@"Rows"]; [self.tableView reloadData]; } return returnArr; } </code></pre> <p>but with no success. What was i trying to do: trying to get to the current item in the table, then set its "isFav" value to NO and then delete the cell from the table, but i'm failing, getting</p> <pre><code> *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary row]: unrecognized selector sent to instance 0x7fd4ab0' </code></pre> <p>I tried to do <code>[NSArray arrayWithObject:indexPath]</code> but i get </p> <pre><code>Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0.

    1. COIt looks like you're trying to reference the property `row` on your dictionary. Since it doesn't have this property you get an error.

Guidance
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.

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