关闭推送通知 ios

Question

我对推送通知有疑问。

我有一个包含所有令牌设备的数据库。这是table.

的结构

ID (number)

APP_NAME (varchar)

APP_TOKEN (varchar)

ENABLE (bool)

如果用户进入设备设置并关闭我的应用程序通知，是否可以将字段启用更改为假？我的意思是，我在 wordpress 中有一个插件向我的数据库中注册的所有设备发送通知，我想知道用户是否 s 关闭通知以将字段 "enable" 到false 然后不发通知给他。

Answer 1

不幸的是，当从“设置”应用程序启用或禁用推送通知时，iOS 没有通知应用程序的委托回调。应用程序需要查询 UIApplication 属性 enabledRemoteNotificationTypes 例如在 applicationDidBecomeActive: 中，然后调用服务器以保存设置，就像您的情况 ENABLE = NO.

然而，即使服务器在用户选择不收听时发送通知，iOS 也会忽略该通知。

Answer 2

您必须在应用程序启动时检查启用的通知标志。然后通过服务器调用相应地设置启用标志

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types == UIRemoteNotificationTypeNone) {
     //set your flag to disabled
}

Answer 3

您可以查看所有类型的通知cf this question：

BOOL remoteNotificationsEnabled, noneEnabled,alertsEnabled, badgesEnabled, soundsEnabled = NO;

// iOS8+
if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {

     remoteNotificationsEnabled = [UIApplication sharedApplication].isRegisteredForRemoteNotifications;

     UIUserNotificationSettings *userNotificationSettings = [UIApplication sharedApplication].currentUserNotificationSettings;

     noneEnabled = userNotificationSettings.types == UIUserNotificationTypeNone;
     alertsEnabled = userNotificationSettings.types & UIUserNotificationTypeAlert;
     badgesEnabled = userNotificationSettings.types & UIUserNotificationTypeBadge;
     soundsEnabled = userNotificationSettings.types & UIUserNotificationTypeSound;
}
else {  // iOS 7 and below
      UIRemoteNotificationType enabledRemoteNotificationTypes = [UIApplication sharedApplication].enabledRemoteNotificationTypes;

      noneEnabled = enabledRemoteNotificationTypes == UIRemoteNotificationTypeNone;
      alertsEnabled = enabledRemoteNotificationTypes & UIRemoteNotificationTypeAlert;
      badgesEnabled = enabledRemoteNotificationTypes & UIRemoteNotificationTypeBadge;
      soundsEnabled = enabledRemoteNotificationTypes & UIRemoteNotificationTypeSound;
}

然后根据结果，通过调用 API.
