放弃,对自动释放功能有麻烦。 谁可以向我解释一下何时应该使用? 这与释放有何不同。 另外,我还需要重新建立汽车库? 如何? 以及何时?
电话autorelease 页: 1 当集合收到<代码>drain的电文时,该电文将release/code>发送至其加入的所有物体。
<代码>autorelease/code>在下述情况下使用:一种方法或功能需要放弃对物体的所有权,但需要将其暂时从dealloc上删除,以便其打电话者能够做些什么。 它还有助于创建“方便”方法,使分配物体的代码更加简单。
当你向物体发送<代码>-autorelease时,在一份清单(自动取款池)中添加,当集合被排放或耗尽时,名单上的每一物体均获得<代码>-release。
自动释放只是一种延迟的信息机制。
