预期应用程序在应用程序启动结束时将具有一个根视图控制器。wait_fences：无法收到答复：10004003 [英] Applications are expected to have a root view controller at the end of application launch wait_fences: failed to receive reply: 10004003

问题描述

当我在iPhone模拟器中启动我的应用程序时，它没有任何问题。如果我在设备上启动，它将在打开时仍然崩溃。但是，当我启动模拟器时，它会出现以下问题：

when i launch my application in iphone emulator, it goes without any problem. If i launch on device it will crash as still as i open it. But when i launch emulator it says that problem:

Applications are expected to have a root view controller at the end of application launch
wait_fences: failed to receive reply: 10004003

我该怎么办？
这是我的应用程序委托：

What can i do? This is my application delegate:

.h：

#import <UIKit/UIKit.h>

@class TrovaChiaviViewController;

@interface TrovaChiaviAppDelegate : NSObject <UIApplicationDelegate>
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet TrovaChiaviViewController *viewController;
@end

这是.m

#import "TrovaChiaviAppDelegate.h"
#import "TrovaChiaviViewController.h"

@implementation TrovaChiaviAppDelegate
@synthesize window = _window;
@synthesize viewController = _viewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application
{

}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    [application release];
}

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

}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
}
- (void)applicationWillTerminate:(UIApplication *)application
{

}
- (void)dealloc
{
    [_window release];
    [_viewController release];
    [super dealloc];
}

@end

推荐答案

我看不到您在哪里设置 viewController 属性，添加

I don't see where you are setting your viewController property, add

self.viewController = [[[TrovaChiaviViewController alloc] initWithNibName:@"TrovaChiaviViewController" bundle:nil] autorelease];

在

self.window.rootViewController = self.viewController;
