我正在尝试从Main.storyboard获得一个导航控制器，而不再使用rootviewcontroller的代码，我也使用segues而不是xib文件。请注意，我已设置视图插座，因此不是导致错误的问题。但是，当我运行应用程序时出现错误：
更新1：请仔细查看代码并指出我需要做出的任何更改。在我的Main.storyboard中，有一个NavigationController根视图连接到一个视图控制器，然后从那里连接到另一个视图控制器。

以下是我在某些特定领域的代码：
AppDelegate.h（之前我忽略了rootviewcontroller的代码，一旦我这样做，就会出现错误。如果我不忽略它，我会收到另一个错误，＆＃34;应用程序窗口是期望在应用程序启动结束时有一个根视图控制器＆＃34;：
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
if ([prefs objectForKey:@"PuzzlePicture"] == nil) {
[prefs setBool:FALSE forKey:@"Refresh"];
[prefs setInteger:0 forKey:@"PuzzlePicture"];
[prefs setBool:TRUE forKey:@"CountMoves"];
//[prefs setBool:TRUE forKey:@"Timer"];
[prefs setInteger:1 forKey:@"PuzzleLayoutX"];
[prefs setInteger:1 forKey:@"PuzzleLayoutY"];
}
/*self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
SliderGaloreViewController *sliderGaloreViewController =
(SliderGaloreViewController *)[storyboard
instantiateViewControllerWithIdentifier:@"SliderGaloreViewController"];
self.window.rootViewController = sliderGaloreViewController;
[self.window makeKeyAndVisible];*/
return YES;
ViewController.m：
- (IBAction)showInfo:(id)sender
{
[self performSegueWithIdentifier:@"showInfo" sender:self];
}
/*- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Make sure your segue name in storyboard is the same as this line
if ([[segue identifier] isEqualToString:@"showInfo"])
{
// Get reference to the destination view controller
SliderGaloreFlipsideViewController *vc = [segue destinationViewController];
NSInteger tagIndex = [(UIButton *)sender tag];
// Pass the information to your destination view
[vc setSelectedButton:tagIndex];
}
}*/
答案 0 :(得分：0)
视图控制器具有view属性，运行时在加载控制器时尝试连接该属性。错误表明您的控制器没有定义其中一个。
尝试将view属性与故事板内的UIView相关联，以使加载逻辑感到满意。
