应用加载时iOS内存泄漏

Question

I'm trying to find a memory leak i have on my app. When the application loads i instantly get a memory leak that looks like that in instuments

how can i debug that ? it doesn't reproduce it self no matter how long i run my app or what i do, only when the applications loads.

and here is my code in the delegate

- (void)applicationDidFinishLaunching:(UIApplication *)application 
{   

    tabBarController = [[UITabBarController alloc] init];

    search = [[iPhoneView alloc] initWithNibName:@"iPhoneView" bundle:nil];
    homeNavigationController = [[UINavigationController alloc] initWithRootViewController:search];

    favouritesNavigationController = [[UINavigationController alloc] init];
    favoritesViewController = [[FavoritesViewController alloc]init];
    [favouritesNavigationController pushViewController:favoritesViewController animated:NO];

    aboutUsViewController =[[AboutUsViewController alloc] init];

    UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"toolbox" image:[UIImage imageNamed:@"aboutus"] tag:0];
    aboutUsViewController.tabBarItem = item;
    [item release];

    UITabBarItem *item2 = [[UITabBarItem alloc] initWithTitle:@"αγαπημένα" image:[UIImage imageNamed:@"favorites"] tag:0];
    favouritesNavigationController.tabBarItem = item2;
    [item2 release];

    NSArray *tabBarControllerCollection = [NSArray arrayWithObjects:homeNavigationController,favouritesNavigationController,aboutUsViewController,nil];
    [tabBarController setViewControllers:tabBarControllerCollection animated:NO];

    [window setRootViewController:tabBarController];
    [tabBarControllerCollection release];   //added that for the leaks

    //[window addSubview:tabBarController.view]; for the warning thing about window and root view controller
    [window makeKeyAndVisible];
}



- (void)dealloc {
    [tabBarController release];
    [search release];
    [favoritesViewController release];
    [favouritesNavigationController release];
    [aboutUsViewController release];
    [window release];
    [super dealloc];
}

Answer 1

Please use the Call Tree view of your Leaks, that will show where the problem happened and will help you troubleshoot. Also try with a real device as the simulator might show false-positives.

Answer 2

释放未释放的homeNavigationController ，并检查是否缺少其他地方。
