removeObject是否在NSMutableArray对象中释放对象？

问题描述

我想知道什么时候使用removeObject在数组中删除对象，如果删除的对象正确处理。

I was wondering when you remove an object using removeObject in an array if that removed object is handled properly. Would the object being removed be released?

推荐答案

NSMutableArray会释放它。如果这是它的最后一个retain，它将被释放。从文档：

The NSMutableArray will release it. If that's the last retain on it, it will be deallocated. From the documentation:

请参见。它们的例子实际上指的是 removeObjectAtIndex：：

See the NSMutableArray documentation. Their example, in fact, refers to removeObjectAtIndex::

id anObject = [[anArray objectAtIndex:0] retain];
[anArray removeObjectAtIndex:0];
[anObject someMessage];
