When deleting a row from Uitableview using commitEditingStyle, my app crashes with this error.
Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-1912.3/UITableView.m:1046 .Terminating app due to uncaught exception NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).
This is my code:
- (void)tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
// If row is deleted, remove it from the list.
if (editingStyle == UITableViewCellEditingStyleDelete) {
order *OrderObj= [appDelegate.orderArray objectAtIndex:[indexPath row]];
[appDelegate removeitem:OrderObj];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
} }
Try to change these lines:
ReplyDeleteorder *OrderObj= [appDelegate.orderArray objectAtIndex:[indexPath row]];
[appDelegate removeitem:OrderObj];
to:
[appDelegate.orderArray removeObjectAtIndex:[indexPath row]]; // assuming orderArray is NSMutableArray
Your tableView:numberOfRowsInSection: is returning bad value after the update. Check the value returned before delete and after delete. It must be decreased by 1.
