copied!<p>this error occurs because the <code>dataSource</code> count isn't the same like the actual data. When you delete an item the <code>tableView</code> cells will go down eg. from 10 to 9. But you didn't delete the data from your <code>dataSource</code> so you end up with different <code>count</code> and Xcode poke you a little.</p> <p>As talked (extensively) in chat we got the problem solved with this code:</p> <pre><code>- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [tableView beginUpdates]; NSIndexPath *realIndex = [self realIndexPathForIndex:indexPath]; NSArray *plist = [self readFullPlist]; NSMutableDictionary *theItem = [[[plist objectAtIndex:realIndex.section] valueForKey:@"Rows"] objectAtIndex:realIndex.row]; [theItem setValue:[NSNumber numberWithBool:NO] forKey:@"isFav"]; [self writePlist:plist]; [self refreshTable]; [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView endUpdates]; } } - (NSArray*)readFullPlist { NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *plistPath = [[documentPaths lastObject] stringByAppendingPathComponent:@"tipsList.plist"]; NSFileManager *fMgr = [NSFileManager defaultManager]; if (![fMgr fileExistsAtPath:plistPath]) { NSString *bundlePlistPath = [[NSBundle mainBundle] pathForResource:@"tipsList" ofType:@"plist"]; [self writePlist:[NSArray arrayWithContentsOfFile:bundlePlistPath]]; } return [NSArray arrayWithContentsOfFile:plistPath]; } - (NSIndexPath*)realIndexPathForIndex:(NSIndexPath*)idxPath { NSArray *fullList = [self readFullPlist]; NSArray *subArr = [[fullList objectAtIndex:idxPath.section] objectForKey:@"Rows"]; int row = idxPath.row; int newRow = 0; for (NSDictionary *dic in subArr) { if ([[dic valueForKey:@"isFav"] boolValue]) { if (row == 0) { return [NSIndexPath indexPathForRow:newRow inSection:idxPath.section]; } row--; } newRow++; } return idxPath; } </code></pre>
