'NSInternalInconsistencyException'，原因：'无法在包中加载 NIB：'Xcode 中的 NSBundle

Question

我正在编写一个实现 Google Cloud Messaging 的 iOS 应用。

我想接收授权令牌并将其打印在屏幕上。

我安装了所有必要的东西，并按照 YouTube 上的教程编写了代码。

这是我的代码：

AppDelegate.h

#import <UIKit/UIKit.h>

@class ViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>;

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;

@property (nonatomic) NSString *getton;

@end

AppDelegate.m

#import "AppDelegate.h"
#import "ViewController.h"
#import "GoogleCloudMessaging.h"

@implementation AppDelegate

@synthesize window = _window;
@synthesize viewController = _viewController;
@synthesize getton;

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

- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]] autorelease];
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    self.viewController = [[[ViewController alloc] initWithNibName:@"LaunchScreen.storyboard" bundle:nil] autorelease];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [self registerDeviceToken: deviceToken];
}

- (void) registerDeviceToken:(NSData *)deviceToken {
    NSLog(@"Device Token: %@", deviceToken);
    NSMutableString *string=[[NSMutableString alloc] init];
    int length=[deviceToken length];
    char const *bytes=[deviceToken bytes];
    for (int i=0; i<length; i++) {
        [string appendString:[NSString stringWithFormat:@"%02.2hhx",bytes[i]]];
    }
    NSLog(@"%@",string);
    [self performSelectorInBackground:@selector(connectionWebRegister:)withObject:string];
    [string release];
}

-(void) connectionWebRegister:(NSString *) deviceTokenString {
    NSAutoreleasePool *pool = [NSAutoreleasePool new];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://serviceProvider/registerTokenId?tokenId=%@&app=",deviceTokenString]];
    NSLog(@"APNS URL : %@",url);
    NSData * res = [NSData dataWithContentsOfURL:url];
    getton=deviceTokenString;
    if (res!=nil) {
        NSString *response = [[NSString alloc] initWithBytes: [res bytes] lenght:[res length] encoding: NSUTF8StringEncoding];
        NSLog(@"%@", response);
        [response release];
    }
    [pool drain];
}

- (void)application:(UIApplication *)app didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    NSLog(@"test");
    NSMutableDictionary * test = [userInfo objectForKey:@"aps"];
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"MESSAGE"
                                                     message:[test objectForKey:@"alert"]
                                                    delegate:nil
                                           cancelButtonTitle:@"OK"
                                           otherButtonTitles:nil];
    [alert show];
    [alert release];
}    
@end

ViewController.h 和 ViewController.m 都是空的。

但是当模拟器启动时，它会因以下错误而崩溃：

带有 错误 主.m.

我在互联网上搜索了很多来解决这个问题，但我无法解决它。

那么，有人可以帮助我吗？谢谢！

如果您提到的故事板存在问题，那么

你应该使用，

  UIStoryboard *storyboardobj=[UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil];

self.viewController = [storyboardobj instantiateInitialViewController];

而不是

   self.viewController = [[[ViewController alloc] initWithNibName:@"LaunchScreen.storyboard" bundle:nil] autorelease];
