遵守?NSSecureCoding協議
importFoundation
class ZHFilterIndexPath: NSObject,NSSecureCoding {
? ? static var supportsSecureCoding: Bool { return true } // 需要添加這個靜態(tài)屬性
? ? varcolumn:Int?
? ? varrow:Int?
? ? varitem:Int?
? ? varselected:Bool=true
? ? vartitle:String=""
?//? fileprivate convenience
?? init(_title:String="",_selected:Bool,_column:Int,_row:Int?,_item:Int? =nil) {

}
存儲方式直接存儲自定義對象
?? ? ? let manager = FileManager.default
? ? ? ? var url = manager.urls(for: .documentDirectory, in: .userDomainMask).first
? ? ? ? url?.appendPathComponent("path.txt")
? ? ? ? let datawrite =? NSKeyedArchiver.archivedData(withRootObject:index)
? ? ? ? try? datawrite.write(to: url!)
? ? ? ? if let dataread? = try? Data(contentsOf: url!){
? ? ? ? ? ? let array = NSKeyedUnarchiver.unarchiveObject(with: dataread) as! ZHFilterIndexPath
?? ? ? ? ? ? ? print("********\(array)******\(selectedCollectionViewIndexPaths)")
? ? ? ? }
自定義對象加入數組后存儲
? ? ? ? ? ? UserDefaults.standard.setValue(NSKeyedArchiver.archivedData(withRootObject: selectedCollectionViewIndexPaths), forKey:"personssub")
? ? ? ? ? ? UserDefaults.standard.synchronize()
? ? ? ? //unarchiveObjectWithData(userDefaults.objectForKey("persons")
? ? ? ? ? ? letarray = NSKeyedUnarchiver.unarchiveObject(with: UserDefaults.standard.object(forKey:"personssub")as!Data)as! [ZHFilterIndexPath]
? ? ? ? ? ? print("^^^^^^^^^^^^^^^^^^^^^^^^^^\(array)")
