Question

我的目标是活着，我不确定为什么。我确定原因是显而易见的，但我也是绿色看到它们。我正在观看乐器中的分配，内存永远不会被释放..

我的头文件已附加。我应该如何在这里照顾生意？感谢您的建议/意见。

仅供参考 - 这是使用xcode 4.3开发的ios5。 ARC已启用。

**编辑/补充**

即使我切换到一个完全不同的View Controller（通过storyboard segue），这个UIView仍然存活。我怀疑它是一个强大的参考或参考不能放弃？
据我所知，这种观点从未发布过。
我正在使用intruments new跟踪分配 - ＆gt; allocations =＆gt;选择target-＆gt; ios 5.1 device =＆gt;记录。只是在我触摸时观看图表。

即使在切换到完全不同的View Controller（通过故事板segue）之后，这个UIView仍然存活。我怀疑它是一个强大的参考或参考不能放弃？

我在这里假设你的意思是你将它作为推送到导航控制器堆栈上，或者你是以模态或其他方式呈现：

当您转到新的视图控制器时，不一定要取消分配。原始视图控制器，因此它的视图，因此你的自定义视图仍将保持活着，直到UIKit决定杀死它，因为内存越来越低。此时，您的视图控制器对象仍将保持活动状态，但其视图将被卸载，您将获得viewDidUnload。只有当您从任何导航控制器/选项卡控制器中完全删除该视图控制器时，如果它是模态的，则将其解除，它是否会被完全销毁。

ios为什么我的物品还活着？
