如何在查看后删除通知中心中的推送通知

Question

有没有办法在点击后处理通知中心的推送通知,并在我的应用程序启动后将其删除？

我知道这是破解和削减,但您可以通过更改应用程序上的徽章编号来清除所有通知.

- (void)application:(UIApplication*)application didReceiveRemoteNotification (NSDictionary*)payload
{
    NSLog(@"Received notification: %@", payload);
    //swapping between two badge numbers to clear notifications
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
    ...
}

如果你已经有一个你不想丢失的徽章编号(上面的例子只是简单地清楚徽章编号)你可以做类似的事情

- (void)application:(UIApplication*)application didReceiveRemoteNotification (NSDictionary*)payload
{
    NSLog(@"Received notification: %@", payload);
    /*
     storing current badge number then swapping between 2 values to make sure we 
     clear the badge number. Once this is done set badge number back to original 
     value.
    */
    int badgeNum = [[UIApplication sharedApplication] applicationIconBadgeNumber]
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeNum];
    ...
}

这可能不是最佳做法,但它完成了工作,客户不会知道差异.我喜欢称之为临时.直到我偶然发现一个更好的解决方案.希望这有助于某人!
