objective-c - didActivateNotification 没有响应 NSUserNotification

Question

我正在努力让 osx native 通知正常工作。我可以创建通知，但无法使 didActivateNotification 正常工作。我希望 didActivateNotification 允许我聚焦窗口并从通知中心删除通知。

这是我的代码:notice.m

#import "Notice.h"

@implementation Notice

- (void) notify:(NSDictionary *)message {

    NSLog(@"Notification - Show it");

    NSUserNotification *notification = [[NSUserNotification alloc] init];
    [notification setTitle:[message valueForKey:@"title"]];
    [notification setInformativeText:[message valueForKey:@"content"]];
    [notification setDeliveryDate:[NSDate dateWithTimeInterval:0 sinceDate:[NSDate date]]];
    [notification setSoundName:NSUserNotificationDefaultSoundName];
    NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
    [center scheduleNotification:notification];
}

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

    NSLog(@"Notification - Clicked");

    notification=nil;
    [center removeDeliveredNotification: notification];
}

这是正确触发的:

NSLog(@"Notification - Show it");

但这不是:

NSLog(@"Notification - Clicked");

有什么建议吗？谢谢

您可能必须为 NSUserNotificationCenter 设置委托(delegate):

NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
center.delegate = self;

您还应该确保您的 Notice 类实现 NSUserNotificationCenterDelegate 协议(protocol)。
