iOS - 检查应用程序中的推送通知支持 [英] iOS - Check for push notification support in the app

问题描述

我在应用程序中添加了推送通知。
我的应用程序基于推送通知工作。
当应用程序第一次运行时，它会显示用户是否想要接收推送通知的警报。
是否可以强制接受推送通知？
或者，如果这不可能，我们可以检查是否为此应用设置了推送通知，并以警报终止应用程序？

I added Push notifications to my application. And my application works based on push notifications. When the app runs for the first time, it is showing alert whether user wants to receive push notifications or not. Is it possible to make it mandatory to accept push notifications? Or if this is not possible, can we check whether push notifications are set for this app or not and terminate the application with alert?

推荐答案

您只能检查用户是否已选择接收推送通知：

You can only check whether user have selected to receive push-notifications:

UIRemoteNotificationType status = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (status == UIRemoteNotificationTypeNone)
{
    NSLog(@"User doesn't want to receive push-notifications");
}
