Ios 更新图标的徽章并在单击图标时获得通知消息

每次推送通知到达时，我都会尝试更新图标徽章，当我单击图标时，我希望获得通知消息

对于badge，我尝试在“ApplicationIDReceivereMoteNotifications”中使用本地通知：

那

[UIApplication sharedApplication].ApplicationOnBadgeNumber+=1

它们都不起作用

要通过点击图标来获取通知信息就更难了

提前感谢

这在我的项目中效果很好：

- (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;
}

你在什么地方放了一个“addObserver”？

- (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;
}
