NSUserNotification关闭调用didActivateNotification

Question

自从MacOS 10.13每次我点击NSUserNotification上的关闭按钮时，它都会调用：

- (void) userNotificationCenter:(NSUserNotificationCenter *)center didActivateNotification:(NSUserNotification *)notification

如何阻止此操作或处理close与action按钮

要创建通知，我会这样做：

NSUserNotification *notification = [[NSUserNotification alloc] init];
...
[notification setHasActionButton:false];
[[NSUserNotificationCenter defaultUserNotificationCenter] deliverNotification:notification];
[[NSUserNotificationCenter defaultUserNotificationCenter] setDelegate:(id)self];

且NSUserNotificationAlertStyle中的.plist设置为“alert”

但现在基本上关闭按钮的反应方式与actionButton的反应相同吗？

Answer 1

NSUserNotification具有可以管理通知标识符或hasActionButton值的属性，因此您可以使用if else在同一委托方法中处理关闭与操作按钮

- (void) userNotificationCenter:(NSUserNotificationCenter *)center didActivateNotification:(NSUserNotification *)notification{    
}

Answer 2

这对我有用..

您可以在didActivateNotification:方法

中删除通知

- (void) userNotificationCenter:(NSUserNotificationCenter *)center didActivateNotification:(NSUserNotification *)notification
{
    NSLog(@"Notification - Clicked");
    [center removeDeliveredNotification: notification];
    notification=nil;
}

其中center是......

NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
    [center scheduleNotification:notification];
