Namaste!
Is there a way to programmatically access the Display Name attribute
of the search field for a given predicate?
I've got a number of predicates set up via IB and several of them I
need to be able to change the display name at run time.
If you create your searchField bindings manually rather than in IB
then you can recreate them as and when you require with specific
display names:
NSString *search1 = @"(unitName CONTAINS[cd] $value OR
unitPluralName CONTAINS[cd] $value)";
NSString *search2 = @"(messageStringValue CONTAINS[cd] $value)";
// search all
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
NSLocalizedString(@"All", @"Search field placeholder"),
NSDisplayNameBindingOption,
search1,
NSPredicateFormatBindingOption,
nil];
[self.searchField bind:NSPredicateBinding
toObject:entryController
withKeyPath:@"filterPredicate"
options: options];
Note that searchField exposes additional bindings every time you bind
a predicate. so the next binding requires a suffix to
NSPredicateBinding.
// search entry
options = [NSDictionary dictionaryWithObjectsAndKeys:
NSLocalizedString(@"Entry", @"Search field placeholder"),
NSDisplayNameBindingOption,
search2,
NSPredicateFormatBindingOption,
nil];
[self.searchField bind:[NSPredicateBinding
stringByAppendingString:@"2"]
toObject:entryController
withKeyPath:@"filterPredicate"
options: options];
Thanks!
