为什么没有调用RegisterForRemoteNotificationsWithDeviceToken

Question

我正在制作一个应用程序,我想在其中实现apple推送通知服务.我按照本教程中给出的分步说明进行操作.

但仍然没有调用这些方法.我不知道造成这个问题的原因.谁能帮我？

    - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
        //NSString * token = [[NSString alloc] initWithData:deviceTokenencoding:NSUTF8StringEncoding];
        NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
        NSLog(@"Device Token:%@",str);

        //NSLog(@"Device token is called");
        //const void *devTokenBytes = [deviceToken bytes];
        //NSLog(@"Device Token");
    }

    - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
        NSString *str = [NSString stringWithFormat: @"Error: %@", err];
        NSLog(@"Error:%@",str);    
    }

Answer 1

我有同样的问题:registerForRemoteNotificationTypes:调用既不调用application:didRegisterForRemoteNotificationsWithDeviceToken:也不调用application:didFailToRegisterForRemoteNotificationsWithError:

我最终在Apple的技术说明TN2265的帮助下解决了这个问题.

这就是我做的:

首先,我仔细检查了我确实正确注册了Push Notifications,包括验证我的"aps-environment"密钥的配置文件以及.app文件本身的代码签名.我把它全部设置正确.

然后,我必须在控制台中调试推送通知状态消息(您需要在设备上安装PersistentConnectionLogging.mobileconfig配置文件并重新启动它.请参阅"观察推送状态消息"下的TN2265).我注意到apns进程启动了一个计时器并计算了一个最小的开火日期,这让我怀疑APNS正在通过此时推出的推送通知注册确认消息,如TN2265所示:

重置iOS上的推送通知权限警报

第一次启用推送的应用程序注册推送通知时,iOS会询问用户是否希望接收该应用程序的通知.一旦用户响应此警报,除非设备已恢复或应用程序已卸载至少一天,否则不会再次显示该警报.

如果您想模拟首次运行的应用,可以将应用程序卸载一天.通过将系统时钟向前设置一天或更长时间,完全关闭设备,然后重新打开设备,您可以实现后者而无需实际等待一天.

因此,我从设备中删除了应用程序,然后在"设置"中手动更改了iPhone的日期,重新启动了设备,并重新安装了应用程序.

下次我的代码调用时registerForRemoteNotificationTypes,它会按预期收到回调.

这解决了我的问题.希望能帮助到你.

在iOS 8中,不推荐使用某些方法.请按照以下步骤兼容iOS 8

1.注册通知

if([[UIDevice currentDevice] systemVersion].floatValue >= 8.0)
{
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];    
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge)];
}

2.添加新的2种方法

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
}

//For interactive notification only
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
    //handle the actions
    if ([identifier isEqualToString:@"declineAction"]){
    }
    else if ([identifier isEqualToString:@"answerAction"]){
    }
}

注意:除了didRegisterForRemoteNotificationsWithDeviceToken和之外,iOS 8中还需要以上两种新方法didReceiveRemoteNotification.否则将不会调用委托方法.

Answer 3

在iOS 8中,除了以不同方式请求推送通知访问之外,您还需要以不同方式注册.

申请进入:

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // iOS 8
    UIUserNotificationSettings* settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
} else {
    // iOS 7 or iOS 6
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}

处理注册设备:

// New in iOS 8
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    [application registerForRemoteNotifications];
}

// iOS 7 or iOS 6
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    // Send token to server
}

Answer 4

确保调用代码(根据支持的通知类型进行更新)

[[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];

并且配置文件已启用APNS.启用APNS后,您可能需要重新下载配置文件.如果您遇到麻烦并且出现错误,那么您可能应该创建一个Entitlements.plist并添加具有值"development"或"production"的密钥"aps-environment",具体取决于构建的类型(通常这个键值对是包含在配置文件中,但有时Xcode会乱用它们).

Answer 5

请记住,模拟器中不支持远程通知.因此,如果您在模拟器中运行您的应用程序,didRegisterForRemoteNotificationsWithDeviceToken则不会被调用.

Answer 6

如果在启用和配置Apple推送通知服务之前使用配置文件,则需要再次重新下载配置文件.

从Xcode Organizer和iPhone/iPad删除配置文件.去吧Settings -> General -> Profiles -> [Your provisioning] -> Remove.

安装新下载的配置文件.然后从XCode清理并运行项目.现在didRegisterForRemoteNotificationsWithDeviceToken应该被召唤.

Answer 7

试试这个对我有用，

第一步

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

在上面的方法中添加下面的代码

 UIApplication *application = [UIApplication sharedApplication];
 if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge
                                                                                     |UIUserNotificationTypeSound
                                                                                     |UIUserNotificationTypeAlert) categories:nil];
[application registerUserNotificationSettings:settings];
 } 
 else {
      UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[application registerForRemoteNotificationTypes:myTypes];
     }

第二步

添加下面的代码功能

 #ifdef __IPHONE_8_0
   - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
   {
  //register to receive notifications
  [application registerForRemoteNotifications];
  }

 - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
  {
    //handle the actions
    if ([identifier isEqualToString:@"declineAction"]){
    }
   else if ([identifier isEqualToString:@"answerAction"]){
   }
}
 #endif

您将在以下功能中获得设备令牌

 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
