Instance Method インスタンスメソッド

mutableArrayValueForKey:

Returns a mutable array proxy that provides read-write access to an ordered to-many relationship specified by a given key.

Declaration 宣言

- (NSMutableArray *)mutableArrayValueForKey:(NSString *)key;

Parameters パラメータ

key

The name of an ordered to-many relationship.

Return Value 戻り値

A mutable array proxy that provides read-write access to the ordered to-many relationship specified by key.

Discussion 解説

Objects added to the mutable array become related to the receiver, and objects removed from the mutable array become unrelated. The default implementation recognizes the same simple accessor methods and array accessor methods as valueForKey:, and follows the same direct instance variable access policies, but always returns a mutable collection proxy object instead of the immutable collection that valueForKey: would return.

The search pattern that mutableArrayValueForKey: uses is described in Accessor Search Patterns in Key-Value Coding Programming Guide.
