内存不会减less释放对象时

（^。^）“嗨，再次抱歉我的英文不好，如果有人喜欢纠正我的编辑，我会感激这个”

你是对的。 但是：首先当我点击创buildbutton时，创build新的视图控制器与分配，并保留计数+1自动，当我按下杀死button保留计数-1和等于0这意味着理论上创build的视图控制器，它被删除forms内存我纠正了这样的代码：

- (IBAction)create:(id)sender{ if(vc == nil){ //if is not nil this mean vc have some space of memory reference and vc is not created //if == nil this mean vc does not have space of memory reference so create. vc = [[VC alloc] initWithNibName:@"VC" bundle:[NSBundle mainBundle]];// retain count + 1 [_VW addSubview:vc.view]; } 

和

  - (IBAction)kill:(id)sender{ [vc.view removeFromSuperview]; //When view removeFromSuperview is called also dealloc is called of the vc view [vc release];// retain count - 1 the curren count is equal 0 this mean vc does not have space of memory vc = nil; // remove the reference of memory. } 

* 但是，当我做了专家的configuration文件，我点击button创build和杀死内存不要只减less增长*

对不起，但我不能粘贴图像，因为我是新手张贴，但是当我初始化分配初始化与生活字节584,19kbconfiguration文件和在1分钟生活字节在1,08 MB不要释放只有增长。

我现在不为什么如果我创build和释放正确，请帮助。

您可以使用以下两种方式 – 1.分配一次并释放dealloc –

 - (IBAction)create:(id)sender{ if(vc == nil){ vc = [[VC alloc] initWithNibName:@"VC" bundle:[NSBundle mainBundle]]; [_VW addSubview:vc.view]; } } - (IBAction)kill:(id)sender{ [vc.view removeFromSuperview]; } - (void)dealloc { [vc release]; [super dealloc]; } 

2.每次分配和释放 –

 - (IBAction)create:(id)sender{ if(vc == nil){ vc = [[[VC alloc] initWithNibName:@"VC" bundle:[NSBundle mainBundle]] autorealease]; [_VW addSubview:vc.view]; } } - (IBAction)kill:(id)sender{ [vc.view removeFromSuperview]; } 

现在您可以尝试使用其中任何一种，然后检查内存占用情况。
