Instance Method インスタンスメソッド

release

Decrements the receiver’s reference count.

Required. 必須。

Declaration 宣言 

- (oneway void)release;

Discussion 解説

The receiver is sent a dealloc message when its reference count reaches 0.

You would only implement this method to define your own reference-counting scheme. Such implementations should not invoke the inherited method; that is, they should not include a release message to super.

For more information on the reference counting mechanism, see Advanced Memory Management Programming Guide.

Special Considerations 特別な注意事項

Instead of using manual reference counting, you should adopt ARC—see Transitioning to ARC Release Notes.
