Save Array in NSUserDefaults:

NSUserDefaults.standardUserDefaults().setObject(selection, forKey: "genderFiltersSelection")

Save information of Array in NSUserdefaults with key.

"Retrieve this information(Array) anywhere in the project with same key"

NSArray *arrayList = [[NSUserDefaults standardUserDefaults] valueForKey:@"arrayListing"];
