【问题描述】：
我正在开发一个类似于 Apple 提供的 PageControl 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本地的 NSMutableArray 中。
然后通过加载单元格 nib 以网格格式显示该数组。
我的应用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，我的应用崩溃了。
当我在设备上使用Instruments 运行它时，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：
- 在
didFinishLaunchingWithOptions我调用两个webservices，获取数据 并将其存储在本地数组中 - 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

【问题讨论】：
-
显示你的代码，没有它我们帮不了你
-
也请给我们一个堆栈跟踪。
-
提供堆栈跟踪和调试器消息。谢谢。
-
错误代码不断变化。我今天执行它并在调试器中出错： *** -[__NSArrayM release]: message sent to deallocated instance 0x7ab64f0
