Searching dictionary in array using predicate

Question

I have an array of dictionaries and I want to find the dictionary with desired value for key "guid". Can not get it with this code:

NSPredicate *filter = [NSPredicate predicateWithFormat:@"guid = %@", key];
NSArray *filteredContacts = [selectedValue filteredArrayUsingPredicate:filter];

Answer 1

Try this.

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Name CONTAINS[cd] %@",searchBar.text];

filterdArray = [[hospitalArray filteredArrayUsingPredicate:predicate] mutableCopy];

Where Name is the key contained in the dictionary under the array.

Answer 2

I think you forgot "=" sign.

 NSPredicate *filter = [NSPredicate predicateWithFormat:@"guid == %@", key];
 NSArray *filteredContacts = [selectedValue filteredArrayUsingPredicate:filter];
