我的应用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
以下是来自我的AppDelegate实施文件.m applicationdidfinishlaunchingwithoptions
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
return YES;
}
最佳答案
将此添加到您的应用程序委托中:
self.window.rootViewController = navigationController;
关于ios - 在应用程序启动结束时,应用程序窗口应具有根 View Controller ,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19819730/
