我在导航堆栈上推送一个viewController，当我到达下一个视图并返回然后重新启动视图时它以崩溃结束......这是代码..

SampleViewController *obj=[[SampleViewController alloc]initWithNibName:nil bundle:nil];
    obj.delegate=self; 
    self.title=@"TESTT";
    [self.navigationController pushViewController:obj animated:YES];
    [obj release];

但如果我将objas 设为全局，则不会发生崩溃......我知道它很常见，但我无法弄清楚。

崩溃日志..

如果您不能使用 NSZombies，我们需要进行一些推测才能找到问题所在……

让我们首先将堆栈跟踪颠倒过来。

UIView 被释放（很可能self.view）

7   UIKit                           0x0086d1e0 -[UIView dealloc] + 309
6   UIKit                           0x008710d7 -[UIView(Hierarchy) removeFromSuperview] + 70
5   UIKit                           0x0087142f __UIViewWillBeRemovedFromSuperview + 689
4   UIKit                           0x008760f9 -[UIView(Internal) _invalidateSubviewCache] + 44

这个 UIView 释放它的“subviewCache”（一个 NSArray），它被释放并向它包含的对象发送一个释放消息。

3   libobjc.A.dylib                 0x01922e4d _objc_rootRelease + 47
2   CoreFoundation                  0x01c11e94 -[__NSArrayM dealloc] + 180
1   CoreFoundation                  0x01b30435 CFRelease + 117
0   libobjc.A.dylib                 0x0192209f objc_msgSend + 19

然后应用程序崩溃，因为它很可能试图释放一个已经被释放的对象。

看起来您的子视图之一被过度发布。

在您的代码中搜索那些没有创建alloc但由您发布的对象。分析仪将为您提供帮助。

检查错误的代码，如下所示：

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; // <- autoreleased
[self.view addSubview:aButton];
[aButton release];                                                     // <- released again. Wrong!

如果一个方法不包含alloc, new，copy或者retain你不能release返回它返回的对象，因为该方法返回一个自动释放的对象。

你可以像这段代码一样做

if(obj == nil)
    obj=[[SampleViewController alloc]initWithNibName:nil bundle:nil];
obj.delegate=self; 
self.title=@"TESTT";
[self.navigationController pushViewController:obj animated:YES];

并使对象全局，在这里你不需要释放对象，当你遇到解决内存泄漏问题的这条线时，它可以在下次创建时创建。

我确信在某些时候发布的某些内容存在问题以找到此崩溃，您必须在运行应用程序后注释掉 dealloc 函数（在所有视图控制器中）中的所有发布，并检查您不会在应用程序中发现崩溃。

一旦你到达这一点，一一取消注释 dealloc 函数。你发现崩溃...

SampleViewController *obj=[[SampleViewController alloc]init];
    obj.delegate=self; 
    self.title=@"TESTT";
    [self.navigationController pushViewController:obj animated:YES];
    [obj release];
