The dictionary coming from server is
{
data = ({
email = "a123@gmail.com";
phone = 9804504884;
"user_id" = 11;
username = abcd;
});
}
var dataArray:NSArray = dict.objectForKey("data") as! NSArray
println("names = ,\(dataArray)");
var pre:NSPredicate = NSPredicate(format: "username CONTAINS[c] a")
var result:NSArray = dataArray.filteredArrayUsingPredicate(pre)
println("names = ,\(result)");
I am always getting result blank result array from this swift code. Please help me to resolve this issue. Thanks
Do it like this,
let json = try! NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments) as! NSDictionary
let predicate = NSPredicate(format: "username CONTAINS[C] 'a'")
if let filteredArray = json["data"]?.filteredArrayUsingPredicate(predicate) {
// do something with array
}
