ios - xcode - 在推送通知授权期间检测用户操作

Question

开发带有推送通知的应用程序，我需要知道用户在推送通知授权期间何时点击两个按钮之一(不允许，允许)。

是否有代表可以这样做？

Answer 1

回调将在调用 -[UIApplication registerUserNotificationSettings:] 时进行。用户授予应用程序的设置将作为第二个参数传入。

如果您想查看用户是否拒绝了该选项，您可以检查 !notification.types 是否这样:

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    // Make sure we check for user permission for location
    UIUserNotificationSettings *notificationTypes = [[UIApplication sharedApplication] currentUserNotificationSettings];
    if (!notificationTypes.types) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"You need to enable notifications for this functionality to work." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
    }
}
