iPhone: Crash When Deleting UITableView Rows
- by Ajeet Kumar Yadav
Hi,
I am new in iPhone development. I am developing an application that fetches a value from a database and displays it in a table view. I want to delete table rows one by one but the rows do not delete and the application crashes.
Here is my row deletion code:
- (void)tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{
if(editingStyle == UITableViewCellEditingStyleDelete) {
SanjeevKapoorAppDelegate *appDelegate =(SanjeevKapoorAppDelegate *)[[UIApplication sharedApplication] delegate];
list *animal =[appDelegate.list1 objectAtIndex:indexPath.row];
[appDelegate deleteCoffee];
[self.tableView reloadData];
//Delete the object from the table.
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
I also delete all rows with this action:
-(IBAction)deletebtn:(id)sender{
SanjeevKapoorAppDelegate *appDelegate =(SanjeevKapoorAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate deleteCoffee];
[self.tableView reloadData];
}
How do I properly implement delete in an UITableView?
