我在iOS9中收到两次相同的推送通知,虽然它在iOS8中工作正常.

我使用以下代码注册推送通知:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    // use registerUserNotificationSettings
    UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:( UIUserNotificationTypeSound | UIUserNotificationTypeAlert|UIUserNotificationTypeBadge) categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    // use registerForRemoteNotifications
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert |UIRemoteNotificationTypeBadge)];
}

#else

// use registerForRemoteNotifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

#endif
