Ios 推送通知：DidFailtRegister和didRegister委托均未调用

我正在创建一个支持推送通知的应用程序
我正在遵循所有步骤

在模拟器上给出了误差

Failed to get token, error: Error Domain=NSCocoaErrorDomain Code=3010 "remote notifications are not supported in the simulator" UserInfo=0x5813d20 {NSLocalizedDescription=remote notifications are not supported in the simulator}

但在设备上，它不调用委托方法

didFailToRegisterForRemoteNotificationsWithError  
didRegisterForRemoteNotificationsWithDeviceToken  

我的代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

    NSLog(@"application didFinishLaunchingWithOptions");
    // Override point for customization after application launch.

    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    NSLog(@"My Token is %@",deviceToken);
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
    NSLog(@"Failed to get token, error: %@", error);
}

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
    NSLog(@"Received Notification %@", userInfo);
}

为我解决：

在设备中，转到：

`Settings->Notifications->YourApp->Enable_Notifications`

推送通知

在

iPhone模拟器中不起作用

尝试使用设备进行检查。

正如@kalyan所说，推送通知在模拟器中不起作用 但是，如果你想得到警告，这里是代码的工作 同时使用模拟器和设备（检查目标IPHONE模拟器） 以及iOS7和iOS8（检查注册表通知设置）

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

    #if !TARGET_IPHONE_SIMULATOR
         // New User Notification Settings for iOS8 support
        if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
            UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
            UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types
                                                                                     categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        } else { // for iOS 7
            UIRemoteNotificationType remoteNotificationType = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound;
            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
             remoteNotificationType];
        }

    #endif
}
