I have An Array With Dictionaries example :
(
{
Email = "[email protected]";
Name = "Kate Bell";
Number = "(555) 564-8583";
},
{
Email = "[email protected]";
Name = "Daniel Higgins";
Number = "555-478-7672";
}
)
And i want to filter this dictionary according to 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 am always getting empty array in result from above swift code. Please help me to resolve this issue. Thanks
I suggest using Swift's filter
instead:
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
let filteredArray = arrContact.filter { $0["Name"] == searchText }
print(filteredArray)
if filteredArray.isEmpty {
searchActive = false
} else {
searchActive = true
}
tblData.reloadData()
}
And as mentioned by @LeoDabus in his comment, you can even simplify further:
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
let filteredArray = arrContact.filter { $0["Name"] == searchText }
print(filteredArray)
searchActive = !filteredArray.isEmpty
tblData.reloadData()
}
