cocoa - NSUserNotification 不显示操作按钮

Question

我正在使用此代码:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Insert code here to initialize your application
    NSUserNotification *notification = [[NSUserNotification alloc] init];
    [notification setTitle: @"Title"];
    [notification setSubtitle: @"Subtitle"];
    [notification setInformativeText: @"Informative Text"];

    [notification setHasActionButton: YES];
    [notification setActionButtonTitle: @"Action Button"];
    [notification setOtherButtonTitle: @"Other Button"];

    [notification setSoundName: NSUserNotificationDefaultSoundName];

    [notification setDeliveryDate: [NSDate dateWithTimeIntervalSinceNow: 10]];
    [[NSUserNotificationCenter defaultUserNotificationCenter] scheduleNotification: notification];
}

而且我毫无疑问地得到了，

没有操作按钮或其他按钮。

正如之前的回答中所述，需要将通知类型设置为提醒要显示的操作按钮。如果您想将应用程序的默认通知样式设置为提醒，则需要在 info.plist 中定义键 NSUserNotificationAlertStyle ，并将值设置为 alert。

请参阅 Apple 的 info.plist keys reference了解更多详情:

NSUserNotificationAlertStyle Specifies whether the notification style should be banners, alerts, or none. The default value is banners, which is the recommended style.
