View Pushed many times from didSelectRowAtIndexPath master detail VC ios - ios

Question

I have a problem where same view is pushed many times on selection of a row and if user keeps on clicking on the same row it crashes.
MasterDetailVC.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
LAClaimReport *record = [_claimReports objectAtIndex:indexPath.row];
if ([record.submitted isEqualToNumber:#1])
{ // if i click on clicking here VC is getting pushed and pushed.
[self.detailViewController showReadonlyViewForClaimReport:record];
}
else
{
[self.detailViewController showEditViewForClaimReport:record];
}
}
LADetailViewController.m
#interface LADetailViewController()
{
LAClaimReport *_claimRecord;
}
-(void) showEditViewForClaimReport:(LAClaimReport *) claimReport
{
_claimRecord = claimReport;
[self performSegueWithIdentifier:#"toEditView" sender:self];
// calls LAClaimReportViewController
}
-(void) showReadonlyViewForClaimReport:(LAClaimReport *) claimReport
{
_claimRecord = claimReport;
[self performSegueWithIdentifier:#"toReadonlyView" sender:self];
// calls LACreateReportViewController.
}
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"toEditView"])
{
LAClaimReportViewController *viewController = segue.destinationViewController;
viewController.claimReport = _claimRecord;
}
else if ([[segue identifier] isEqualToString:#"toReadonlyView"])
{
LACreateReportViewController *viewController = segue.destinationViewController;
viewController.claimReport = _claimRecord;
}
}
LAClaimReportViewController & LACreateReportViewController are two diff. VC having segues from LADetailViewController. I want that the VC (LACreateReportViewController or LAClaimReportViewController) should not be pushed many times on multiple click of the same row of the masterDetailVC. pls help.

You can just check if the View is already pushed. If it is then don't push it again. If its not pushed then push it.
For this you can make a instance variable may be a bool. Lets call it isPushed. Make isPushed = true; when you push the view. When you pop it then make isPushed = false;.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
LAClaimReport *record = [_claimReports objectAtIndex:indexPath.row];
if ([record.submitted isEqualToNumber:#1] && !isPushed)
{ // if i click on clicking here VC is getting pushed and pushed.
isPushed = true;
[self.detailViewController showReadonlyViewForClaimReport:record];
}
else
{
[self.detailViewController showEditViewForClaimReport:record];
}
}
The above is just an way. One thing is this: [record.submitted isEqualToNumber:#1] always false? If it is then you would like to check that I think.
Hope this will Help.
