我的应用程序使用两种语言并具有三个选项卡。我的应用程序中有一个语言更改按钮，每当更改所有选项卡的标题时，都必须根据语言更改。这是我使用的代码，它在 iPad 中运行良好，但相同的代码在 iPhone 中崩溃。这两个设备都是在 iOS5 中。
viewController1 = [[MapFirstViewController alloc] initWithNibName:@"MapFirstViewController_iPad" bundle:nil];
viewController1.tabBarItem = [[UITabBarItem alloc] initWithTitle:[self languageSelectedStringForKey:@"about"] image:[UIImage imageNamed:@"about_tabbar_icon.png"] tag:8];
viewController2 = [[MapSecondViewController alloc] initWithNibName:@"MapSecondViewController_iPad" bundle:nil];
viewController2.tabBarItem= [[UITabBarItem alloc] initWithTitle:[self languageSelectedStringForKey:@"Map"] image:[UIImage imageNamed:@"maps_tabbar_icon.png"] tag:9];
viewController3 = [[ViewListIpad alloc] initWithNibName:@"ViewListIpad" bundle:nil];
viewController3.tabBarItem= [[UITabBarItem alloc] initWithTitle:[self languageSelectedStringForKey:@"eKiosks & eSC List"] image:[UIImage imageNamed:@"esc&kiosk_tabbar_icon.png"] tag:10];
MapAppDelegate *appDelegate = (MapAppDelegate *)[[UIApplication sharedApplication] delegate];
NSMutableArray *viewControllersArray = [NSMutableArray arrayWithArray:[[appDelegate tabBarController] viewControllers]];
[viewControllersArray replaceObjectAtIndex:0 withObject:viewController1];
[viewControllersArray replaceObjectAtIndex:1 withObject:viewController2];
[[appDelegate tabBarController] setViewControllers:viewControllersArray animated:NO];
崩溃日志：
