iOS 8推送通知操作在后台激活模式下不起作用

Question

I am experiencing a problem with the following lines of code :

    UIMutableUserNotificationAction *cancelAction = [[UIMutableUserNotificationAction alloc] init];
    cancelAction.identifier = kCancelIdentifier;
    cancelAction.title = @"Cancel";
    cancelAction.activationMode = UIUserNotificationActivationModeBackground;
    cancelAction.destructive = YES;
    cancelAction.authenticationRequired = YES;

When responding to this action of the push notification, it will always open up the application rather than performing task in the background.

Answer 1

您可以设置activationMode为acceptAction不cancelAction 。
