更新图标徽章，并在单击图标时获取通知消息

Question

每次推送通知到达时，我都会尝试更新图标徽章，当我点击图标时我想收到通知消息。

对于徽章，我尝试在＆＃34; applicationDidReceiveRemoteNotifications＆＃34;中使用本地通知：

UILocalNotification * setBadge = [[UILocalNotification alloc] init];

    UIApplication * app = [UIApplication sharedApplication];

    setBadge.timeZone = [NSTimeZone defaultTimeZone];

    // Update the badge of app when a notif appears
    setBadge.applicationIconBadgeNumber += 1;

    setBadge.fireDate = [NSDate dateWithTimeIntervalSinceNow:2];

    [app scheduleLocalNotification:setBadge];

那个

[UIApplication sharedApplication] .applicationIconBadgeNumber + = 1;

它们都不起作用。

通过点击图标来获取通知消息更难

提前致谢

这在我的项目中运作良好：

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    self.isBackground = NO;
    [[NSNotificationCenter defaultCenter] postNotificationName:AppChangeState object:@(self.isBackground)];
    [[NSNotificationCenter defaultCenter] postNotification:[NSNotification notificationWithName:DID_BECOME_ACTIVE
                                                                                         object:nil
                                                                                       userInfo:nil]];

    [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
}
