# takeStoredValue(_:forKey:)

Sets the value of the property identified by a given key.

## Declaration

```swift
func takeStoredValue(_ value: Any?, forKey key: String)
```

## Discussion

Discussion This method is used to initialize the receiver with values from an object store (generally, this storage is ultimately from a database) or to restore a value from a snapshot. The default implementation is similar to the implementation of takeValue(_:forKey:), but it resolves key with a different method/instance variable search order: Searches for a private accessor method based on key (a method preceded by an underbar). For example, with a key of “lastName”, takeStoredValue(_:forKey:) looks for a method named _setLastName:. If a private accessor is not found, searches for an instance variable based on key and sets its value directly. For example, with a key of “lastName”, takeStoredValue(_:forKey:) looks for an instance variable named _lastName or lastName. If neither a private accessor nor an instance variable is found, takeStoredValue(_:forKey:) searches for a public accessor method based on key. For the key “lastName”, this would be setLastName:. If key is unknown, takeStoredValue(_:forKey:) calls handleTakeValue(_:forUnboundKey:). This different search order allows an object to bypass processing that is performed before setting a value through a public API. However, if you always want to use the search order in takeValue(_:forKey:), you can implement the class method useStoredAccessor() to return NO. And as with value(forKey:), you can prevent direct access of an instance variable with the class method accessInstanceVariablesDirectly.
