捕获对“应用程序想要向您发送推送通知"的回答；警报 [英] Capture answer to "App would like to send you push notifications" alert

问题描述

第一次在 UIApplication 对象上调用 registerForRemoteNotificationTypes: 时，a UIAlertView 会弹出说[app] 想要发送给你推送通知".

The first time you call registerForRemoteNotificationTypes: on your UIApplication object, a UIAlertView pops up saying "[app] would like to send you push notifications".

有什么方法可以知道在此 AlertView 中何时点击了确定"或不允许"?

Is there any way to know when "OK" or "Don't allow" is tapped in this AlertView?

目前 application:didRegisterForRemoteNotificationsWithDeviceToken: 在我的 AppDelegate 上被调用，甚至在用户做出决定之前.

Currently application:didRegisterForRemoteNotificationsWithDeviceToken: is called on my AppDelegate, even before a user makes a decision.

我问的原因是因为在第一次启动时，我想推送一个带有 Notification 选项的 ViewController，但前提是用户表示他们想要接收通知.

The reason I ask is because on first launch, I want to push a ViewController with Notification options, but only if the user indicated that they want to receive notifications.

推荐答案

你可以使用UIApplication的next方法:

You can use next method of UIApplication:

返回应用程序接受的通知类型.

- (UIRemoteNotificationType)enabledRemoteNotificationTypes

例如

UIRemoteNotificationType status = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (status == UIRemoteNotificationTypeNone)
{
     NSLog(@"user is not subscribed to receive push notifications");
}
