我正在使用 Tab Bar View App，并且正在使用情节提要，我的 Xcode 版本是 4.3.3。基本上我的应用程序过去加载正常，但后来我添加了第三个视图和第三个视图控制器，它无法正确加载，所以我删除了它们，现在它无法正确加载：/它加载了启动屏幕，但它没有再往前走。

这是我的 AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UIViewController *FirstViewController;

@end

还有我的 AppDelegate.m

#import "AppDelegate.h"

@implementation AppDelegate

@synthesize window = _window;
@synthesize FirstViewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    return YES;
}

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

    // Override point for customization after app launch    
    [_window addSubview:FirstViewController.view];
    [_window makeKeyAndVisible];
}

@end

您是否忘记在情节提要的身份检查器中为视图控制器设置自定义类？
