如何在瀏覽後刪除通知中心的推送通知

Question

點擊後有沒有辦法處理來自通知中心的推送通知，並在我的應用程序啓動後將其刪除？

我知道這是黑客和斜槓，但您可以通過更改您的應用程序上的徽章號碼來清除所有通知。

- (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]; 
    ... 
} 

如果你已經有了你不想失去徽章數量，你可以這樣做

- (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]; 
    ... 
} 

（例如將最終只是明確徽章號以上），這可能不是最佳實踐，但它完成了工作，客戶不會知道其中的差異。我喜歡稱它爲臨時。修復，直到我偶然找到更好的解決方案。希望這可以幫助別人！
