Dictionary object won't predicate - objective-c

Question

I have a json object coming in as
{
"c_id": "261",
"customer_id": "178729",
"name": "Three, Test"
},
{
"c_id": "261",
"customer_id": "178727",
"name": "Two, Test"
},
{
"c_id": "261",
"customer_id": "178728",
"name": "Two, Test"
},
{
"c_id": "261",
"customer_id": "185186",
"name": "Valid, Another"
},
{
"c_id": "261",
"customer_id": "183889",
"name": "White, Betty"
}
However when this code processes
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableArray *tempCustomers = [[NSMutableArray alloc] init];
for (NSDictionary *dict in [json objectForKey:#"data"]) {
NSLog(#"dict: %#", dict);
NSLog(#"name: %#", [dict objectForKey:#"name"]);
[tempCustomers addObject:dict];
}
self.customers = tempCustomers;
NSLog(#"Customers: %#",customers);
self.customerData = [self partitionObjects:[self customers] collationStringSelector:#selector(self)];
NSLog(#"CustomerData: %#",customerData);
-(NSArray *)partitionObjects:(NSArray *)array collationStringSelector:(SEL)selector
{
UILocalizedIndexedCollation *collation = [UILocalizedIndexedCollation currentCollation];
NSInteger sectionCount = [[collation sectionTitles] count];
NSMutableArray *unsortedSections = [NSMutableArray arrayWithCapacity:sectionCount];
for (int i = 0; i < sectionCount; i++) {
[unsortedSections addObject:[NSMutableArray array]];
}
for (id object in array) {
NSInteger index = [collation sectionForObject:[object objectForKey:#"name"] collationStringSelector:selector];
[[unsortedSections objectAtIndex:index] addObject:object];
}
NSMutableArray *sections = [NSMutableArray arrayWithCapacity:sectionCount];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:#"name" ascending:YES];
NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
for (NSMutableArray *section in unsortedSections) {
NSArray *sortedArray = [section sortedArrayUsingDescriptors:sortDescriptors];
//NSLog(#"Sort: %#",sortedArray);
//[sections addObject:[collation sortedArrayFromArray:section collationStringSelector:selector]];
[sections addObject:sortedArray];
}
return sections;
}
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
NSLog(#"Search Display Controller: %#", self.customerData);
//NSString *predicateString = [NSString stringWithFormat:#"name CONTAINS[cd] '%#'",searchString];
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"name CONTAINS[cd] '%#'",searchString];
self.filteredCustomers = [[self.customerData filteredArrayUsingPredicate:predicate] mutableCopy];
NSLog(#"Filtered Customers %#", self.filteredCustomers);
return YES;
}
It shows

Notice the " " around the name key are missing. I believe this is why my NSPredicate in my searchDisplayController isn't working. Why are the quotes being removed and how would I fix my searchDisplayController to work?

Answer 1

I just noticed, in your predicate, you have single quotes around the %# -- they shouldn't be there. Putting the single quotes around %# turns it into a literal.
