注册后更新解析deviceToken

Question

目前，我坐在一些空的deviceToken字段中。我发现这是因为在创建安装对象之前添加组存在问题 - 它会阻止后续的创建工作。

我现在要做的是再次获取deviceToken并在Parse中更新它，但问题是，didRegisterForRemoteNotificationsWithDeviceToken在第一次之后永远不会再次运行...

在初次调用didRegisterForRemoteNotificationsWithDeviceToken之后获取设备令牌的任何方法？

Answer 1

这适用于iOS 8：

Enum.reduce/3

Answer 2

可以重复调用

didRegisterForRemoteNotificationsWithDeviceToken。只需在方法AppDelegate.m中调用didFinishLaunchingWithOptions中的推送注册码即可。

以下是我使用的内容：

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

就是这样 - 如果你每次调用它，你将在每次加载时获得didRegisterForRemoteNotificationsWithDeviceToken的委托回调。
