uitabbarcontroller在启动时崩溃

我有一个iPhone应用程序，它具有一个根视图，并带有一个按钮，该按钮可导致标签栏视图。当你在根视图中点击UIbutton时，它会触发一个执行下面代码的IBAction方法。从某种原因，它崩溃到最后。有任何想法吗？会很高兴得到任何帮助...谢谢！uitabbarcontroller在启动时崩溃

rootview.h

@interface RootView : UIViewController 

@property (strong, nonatomic) UIWindow *window; 

@property (strong, nonatomic) UITabBarController *tabBarController; 

@end

rootview.m

-(IBAction)GoToTabBarView:(id)sender { 

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
UIViewController *viewController1 = [[FirstView alloc] initWithNibName:@"FirstView" bundle:nil]; 
UIViewController *viewController2 = [[SecondView alloc] initWithNibName:@"SecondView" bundle:nil]; 
self.tabBarController = [[UITabBarController alloc] init]; 
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil]; 
self.window.rootViewController = self.tabBarController; 
[self.window makeKeyAndVisible]; 


}

应用崩溃的位置：

self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];

我在做什么错？谢谢！！

是否有崩溃记录？尝试使用NSLog（@“％@％@”，viewController1，viewController2）;' –

记录要添加到数组中的值是否为'nil'，否则它们不是零。日志： – TommyG

似乎是'NIB'中的错误。你有没有检查他们的“视图”属性？错误明确提到。 –

很难，而无需任何错误信息的话。但你有没有试过

NSMutableArray *listOfViewControllers = [[NSMutableArray alloc] init]; 
UIViewController *vc; 

vc = [[FirstView alloc] initWithNibName:@"FirstView" bundle:nil]; 
[listOfViewControllers addObject:vc]; 
[vc release]; 
vc = [[SecondView alloc] initWithNibName:@"SecondView" bundle:nil]; 
[listOfViewControllers addObject:vc]; 
[vc release]; 

[self.tabBarController.viewControllers setViewControllers:listOfViewControllers];

另外，你确定你的笔尖存在吗？您应该使用该软件包：

[[FirstView alloc] initWithNibName:@"FirstView" bundle:NSBundle.mainBundle];

+1查看上面更新的日志。您建议的修复程序没有帮助，但是谢谢:) – TommyG

因此，您必须连接界面构建器中的视图。您可以通过按住Ctrl键并单击文件所有者来完成此操作，然后将视图拖到FirstView –
