I'm getting a crash report from Crashlytics that is always in the same place but I'm unable to replicate the crash.
It seems to be only users on iOS 9 and only very occasionally. I'm not sure if it's a code issue or something else. The last line mentions libdispatch.dylib
as being missing, again, not sure if relevant.
Crashlytics indicates that the crash occurs at MMDetailTableVC.m
line 1407, which is the reloadData
line.
Here's what is reported:

And here's my code for saveItemEntry
that always seems to be the place where the crash occurs.
- (void)saveItemEntry:(MMitem *)item{
if (item)
{
NSString *resultStr = [self.meetingModel saveItem:item];
if ([resultStr isEqualToString:@"OK"])
{
// all good so close form and refresh data
[_itemViewController dismissViewControllerAnimated:NO completion:nil];
[self.tableView reloadData];
// or if there is an error result then display message
}
else if ([resultStr isEqualToString:@"DescriptionNotesMissing"])
{
[self showAlert:@"Missing Description or Notes" :@"An Item Description or Notes is required" :0];
[self.itemViewController.itemDescription becomeFirstResponder];
}
// for any other error do nothing
}
}
