应用程序窗口应在应用程序启动结束时具有根视图控制器

Question

我的应用程序启动时出现上述错误.以下代码来自我的AppDelegate .h文件

#import <UIKit/UIKit.h>

@interface TableViewAppDelegate : NSObject <UIApplicationDelegate> {

UIWindow *window;
UINavigationController *navigationController;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UINavigationController *navigationController;

@end

以下内容来自我的AppDelegate实现文件.m applicationdidfinishlaunchingwithoptions

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

//Configure and show the window
[window addSubview:[navigationController view]];

[window makeKeyAndVisible];

return YES;
}

在您的应用委托中添加此内容:

self.window.rootViewController = navigationController;
