试图让我的 iPhone 应用程序变得通用。导航控制器一直显示呼叫不平衡

Question

我已经尝试了几个小时来让我的 iPhone 应用程序变得通用。任务很成功，但遇到了一个奇怪的问题。导航控制器不断推动东西，甚至不推动任何东西。该应用程序不会崩溃，但它在控制台中给我一条消息

嵌套推送动画可能会导致导航栏损坏 2012-02-06 10:52:07.701 @#$%^^$[54755:207] 在意外状态下完成导航转换。导航栏子视图树可能会损坏。 2012-02-06 10:52:07.704 !@#$%^$%#[54755:207] 对的开始/结束外观转换的调用不平衡。

这是我如何设置应用程序的整个过程：

这是我在 AppDelegate_iphone.h 中的代码

#import <UIKit/UIKit.h>
#import "iPhoneView.h"
#import "AboutUsViewController.h"
#import "FavoritesViewController.h"

@class iPhoneView;

@interface AppDelegate_iPhone : NSObject <UIApplicationDelegate> {

    UITabBarController *tabBarController;
    UINavigationController *homeNavigationController;
    UINavigationController *favouritesNavigationController;
    AboutUsViewController *aboutUsViewController;

    iPhoneView * search;
    FavoritesViewController *favoritesViewController;
    UIWindow *window;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet iPhoneView *search;
@property (nonatomic, retain) FavoritesViewController *favoritesViewController;

@end

，这是我的 AppDelegate.m 文件中的代码

#import "AppDelegate_iPhone.h"
#import "iPhoneView.h"

@implementation AppDelegate_iPhone

@synthesize window,search,favoritesViewController;

    [homeNavigationController pushViewController:search animated:NO];

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

    aboutUsViewController =[[AboutUsViewController alloc] init];

    UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"επικοινωνία" 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 addSubview:tabBarController.view];
    [window makeKeyAndVisible];
}

OK，解决了在 IB 中使用相同操作连接按钮 2 次的问题。我花了48个小时才弄清楚！
