清除通知欄所有通知

//只要設定角標不相同時，再設定為0就可以清除
[UIApplication sharedApplication].applicationIconBadgeNumber = 1;
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;

推送通知進入後臺處理通知訊息

1.後臺推送訊息設定，要再推送訊息中加入鍵值對__"content-available" = 1__。這種方式為靜默推送 例如：

aps =     {
        alert = "一條新的訊息";
        "content-available" = 1;
        sound = default;
    };
 

2.App端的需要遠端通知後臺模式，在plist新增如下key

<key>UIBackgroundModes</key>
<array>
    <string>fetch</string>
    <string>remote-notification</string>
</array>

訊息處理在如下方法回撥中

- (void)application:(UIApplication *)application
    didReceiveRemoteNotification:(NSDictionary *)userInfo
          fetchCompletionHandler:
              (void (^)(UIBackgroundFetchResult))completionHandler {
              NSLog(@"收到推送通知:%@", userInfo);
  completionHandler(UIBackgroundFetchResultNewData);
}
