我的retainCount正在增加？
Yah*_*hia 2 memory iphone dealloc retaincount popviewcontrolleranimated
我正在尝试构建rss阅读器,当用户完成阅读artical并按回dealloc时不会调用的问题
我得到了retainCount 6和7次!
我有很多自定义面板
当按下后退按钮时,视图是poped并且没有dealloc被称为？!

增加:
当我调用我使用过的Artical时
avc=[[ArticalViewController alloc]initWithNibName:@"ArticalViewController" bundle:nil];
avc.artical=[self.feeds objectAtIndex:indexPath.row];
[self.navCon pushViewController:avc animated:YES];
[avc release];

我发现追踪保留计数和缺少保留 - 释放对的最佳方法是使用Instruments.点击个人资料(Cmd ⌘+ I)并选择泄漏模板.即使不会自动发现泄漏,也会记录保留更改,因此您可以手动跟踪其他保留.为此,请在选择分配工具时在" 对象摘要"中查找您的类名.如果找不到,则表示所有实例都已取消分配.否则,单击选择类名时出现的箭头:
您将看到您班级的所有生活实例:
如果您认为某些实例应该已经解除分配,请选择一个并单击对象地址旁边的箭头.现在,您应该看到使用执行此操作的方法名称在此对象上调用的任何保留或释放:
RefCt列显示调用操作后的retainCount,当您双击任何保留/释放时,乐器将显示执行此操作的代码行:
如您所见,对象被添加到数组中,并且永远不会从中删除.
根据我的经验,这是找到泄漏仪器不会自动检测到的内存泄漏的最快速,最简单的方法.我认为另一个好的做法是在对象摘要中查看#Living以确保生存实例的数量完全符合您的预期.
