Question

This is the error I am reciving when I select a value from my UITableView

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Can't do regex matching, reason: Can't open pattern U_ILLEGAL_ARGUMENT_ERROR (string Motron, pattern 
libc++abi.dylib: terminate called throwing an exception
(lldb) 

This is the first time I have had an error like this.. I am receiving it in my tableview method didSelectRowAtIndexPath on the second line of code shown below

// This predicate restricts the filterDataArray to the related values of the selected index
            NSPredicate *predicate = [NSPredicate predicateWithFormat:@"%K like %@",@"MASTER",cell.textLabel.text];
            filterDataArray = [dataArrayOfDictionaries filteredArrayUsingPredicate:predicate];

I have logged out the array of dictionaries and this is what one of the dictionary values looks like.

{
        HASM = 1;
        ISM = 0;
        ISV = 0;
        MASTER = Merc;
        MANURE = 96;
    }

There are about 60 or 17 of these dictionaries in the array.
any help would be greatly appreciated.

I think you are not correctly using predicate in this case, try this

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"MASTER CONTAINS [c]%@", cell.textLabel.text];
filterDataArray = [dataArrayOfDictionaries filteredArrayUsingPredicate:predicate];
