Question

如何在iOS 8中获取设备令牌以进行远程通知？我在iOS＆lt; {1}}中使用了didRegisterForRemoteNotificationsWithDeviceToken方法。 8，它返回了设备令牌。但是在iOS 8中，它没有。

Answer 1

阅读UIApplication.h中的代码。

你会知道怎么做。

首先：

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

像这样添加代码

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
#ifdef __IPHONE_8_0
  UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert 
      | UIUserNotificationTypeBadge 
      | UIUserNotificationTypeSound) categories:nil];
  [application registerUserNotificationSettings:settings];
#endif
} else {
  UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
  [application registerForRemoteNotificationTypes:myTypes];
}

如果您不同时使用Xcode 5和Xcode 6 ，请尝试此代码

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

（感谢@zeiteisen @dmur的提醒）

第二

添加此功能

#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

你可以在

中获得deviceToken

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

如果仍然不起作用，请使用此功能并NSLog 错误

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error

Answer 2

注册iOS 8并继续支持旧版本的方式

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];
}

并在app delegate中添加

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    [application registerForRemoteNotifications];
}

iOS8可以在未经许可的情况下收到无声通知。呼叫 - (void)registerForRemoteNotifications。在此application:didRegisterForRemoteNotificationsWithDeviceToken:之后将被调用

注意：仅当应用程序已成功注册具有以下功能的用户通知或启用了后台应用程序刷新时，才会调用带有令牌的回调。

如果启用了任何通知类型，请检查您的应用设置。如果没有，您将无法获得设备令牌。

您现在可以使用

获取静音通知

aps {
content-available: 1
}

通知有效载荷中的

但是出现的通知仍然需要获得许可。致电

UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert;
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[application registerUserNotificationSettings:notificationSettings];

此代码应该请求许可。

您现在应该准备好获得推送通知

Answer 3

在我的情况下，我已经进行了必要的更新以请求iOS 7和iOS 8的推送通知访问，但是当iOS 8用户授予访问权限时，我还没有实现新的回调。我需要将此方法添加到我的应用代理中。

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    [application registerForRemoteNotifications];
}

Answer 4

如果您使用Xamarin.iOS构建移动应用程序，则可以使用此代码段来请求推送通知注册

if (UIDevice.CurrentDevice.CheckSystemVersion(8,0))
{
    UIUserNotificationType userNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound;
    UIUserNotificationSettings settings = UIUserNotificationSettings.GetSettingsForTypes(userNotificationTypes, null);
    UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);
}
else
{
    UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
    UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
}

此外，您需要覆盖DidRegisterUserNotificationSettings方法以获取从APNS服务器返回的设备令牌：

public override void DidRegisterUserNotificationSettings(UIApplication application, UIUserNotificationSettings notificationSettings)
{
    application.RegisterForRemoteNotifications();
}

Answer 5

Madao（https://stackoverflow.com/a/24488562/859742）的回答是对的，但......

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge

应该更多＆＃34;正确＆＃34;

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil];

这些标志具有相同的位掩码值，这就是为什么两者都可以工作但UIUserNotificationSettings需要UIUserNotificationType而不是UIRemoteNotificationType。

除此之外，我会打电话给

[application registerUserNotificationSettings:settings];

在AppDelegate方法中（取决于授予的权限），

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings

Answer 6

我认为保持向后兼容性的更好方法我们可以采用这种方法，它适用于我的案例希望为你工作。也很容易理解。

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

Answer 7

UIUserNotificationType types = UIUserNotificationTypeBadge |
    UIUserNotificationTypeSound | UIUserNotificationTypeAlert;

    UIUserNotificationSettings *mySettings =
    [UIUserNotificationSettings settingsForTypes:types categories:nil];

    [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];

    [application registerForRemoteNotifications];
