我已经搜索了互联网，并且在收到推送通知时找不到激活徽章计数的方法。我正在使用目标C，并将在下面添加appdelegate.m。
以前，我们曾经使用过硬编码方式发送徽章计数，该徽章计数从内部通知选项中获取徽章计数并在应用程序上显示出来，但这不是正确的方法，因为甚至会显示未读的通知。应用程序打开后，徽章会重置，并且在收到通知时会继续从以前的计数而不是从1开始计数。
我通过添加来解决
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
to
- (void)applicationDidBecomeActive:(UIApplication *)application
此问题已解决并正确重置了计数。

仅在接收推送通知时需要显示徽章计数，并且应相应增加计数，而无需使用硬编码方法。请帮忙。
