I have an example of an array with a dictionary:
(
{
Email = " [email protected]";
Name = "Kate Bell";
Number = "(555) 564-8583";
},
{
Email = "[email protected]";
Name = "Daniel Higgins";
Number = "555-478-7672";
}
)
I want to filter this dictionary based on the key “name”
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
let predicate = NSPredicate (format:"Name == %@", searchText)
let filteredArray = (arrContact as NSMutableArray).filteredArrayUsingPredicate(predicate)
print(filteredArray)
if(filteredArray.count == 0 ){
searchActive = false;
} else {
searchActive = true;
}
tblData.reloadData()
}
I always get empty array from above swift code. Please help me to solve this problem. Thank you
Try this swift 3
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
// Put your key in predicate that is "Name"
let searchPredicate = NSPredicate(format: "Name CONTAINS[C] %@", searchText)
let array = (arrContact as NSArray).filtered(using: searchPredicate )
print ("array = \(array)")
if(array.count == 0){
searchActive = false;
} else {
searchActive = true;
}
self.aTable.reloadData()
}
