我正在开发一个类似于PageControlApple 提供的示例的应用程序。我的应用程序从服务器获取数据并将其存储在NSMutableArray本地。然后通过加载单元格nib以网格格式显示该数组。

我的应用程序在擦除过程中在模拟器上运行，但当我尝试在设备上运行它时，我的应用程序崩溃了。

此外，当我在使用它的设备上运行它时，Instruments它执行得很好。

已启用僵尸并出现以下错误。

*** -[__NSArrayM release]: message sent to deallocated instance 0x18aef0

这就是我正在做的事情：

  1. 在didFinishLaunchingWithOptions我调用两个网络服务时，获取数据并将其存储在本地数组中
  2. 推送生成页面的视图控制器

试图解决同样的问题。

这是我的代码。



    //**AppDelegate.h**
    @interface TumBhiAppDelegate : UIResponder  {
    NSMutableArray *arrDetailsByCategory;
    }
    @property (nonatomic, retain) IBOutlet NSMutableArray *arrDetailsByCategory;    
    -(IBAction)doneProcessing:(id)sender;
    @end

    //**AppDelegate.m**
    #import "AppDelegate.h"
    #import "Server.h"

    @implementation AppDelegate
    @synthesize arrDetailsByCategory;
    //Once processing is done push the view
    -(IBAction)doneProcessing:(id)sender
    {    
    BaseContentViewController *baseController = [[BaseContentViewController alloc] initWithNibName:@"BaseContentViewController" bundle:nil];    
    [self.navigationController pushViewController:baseController animated:YES];    
    [baseController release];
    }

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
    arrDetailsByCategory  = [[NSMutableArray alloc] init];
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    self.viewController = [[TumBhiViewController alloc] initWithNibName:@"TumBhiViewController" bundle:nil];

    self.navigationController = [[UINavigationController alloc]initWithRootViewController:self.viewController];
    [self.navigationController setNavigationBarHidden:YES];

    self.window.rootViewController = self.navigationController;
    [self.window makeKeyAndVisible];
    //getDetails is called 5-6 time
    //arrDetailsByCategory is populated accordingly 
    [Server getDetails:@"ABC"];
    [self doneProcessing:nil];
    return YES;
    }
    @end

    //**Server.h**
    @interface ServerCommunication : NSObject{
    }
    -(BOOL)getDetails:(NSString *)str
    @end

    //**Server.m**
    #import "Server.h"
    #import "AppDelegate.h"
    @implementation ServerCommunication

    -(BOOL)getDetails:(NSString *)str
    {
    NSMutableArray *arrFinal = [NSMutableArray array];
    //call web-service populate arrFinal
    [[[AppDelegate GetAppDelegate] arrDetailsByCategory] addObjectsFromArray:arrFinal];
    }
   @end

可能是在将发布消息发送给它之前，您的数据数组可能会因任何逻辑错误而被解除分配

使用断点检查它在哪里被释放
