Parse.com和ios的安装和徽章问题

我在ios应用程序上使用安装,推送和徽章(parse.com sdk 1.7.2.2) 几天前我注意到了一些事情, 如博客文章(旧版http://blog.parse.com/announcements/badge-management-for-ios/

中所述,将徽章重置为0的代码
// Clear badge if needed
PFInstallation *currentInstallation = [PFInstallation currentInstallation];

if (currentInstallation.badge != 0) {
    currentInstallation.badge = 0;
    [currentInstallation saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (!succeeded) [ErrorHandler handle:@"save installation failed" forError:error];
    }];
}

不再有用了, 一切都很好(没有解析错误),但徽章计数保持在数据库中的旧值

我第二次尝试了一下,似乎在一段时间内效果更好:

PFInstallation *currentInstallation = [PFInstallation currentInstallation];

if (UIApplication.sharedApplication.applicationIconBadgeNumber > 0 || currentInstallation.badge > 0) {
    UIApplication.sharedApplication.applicationIconBadgeNumber = 0;
    currentInstallation.badge = 0;
    [currentInstallation saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
    {
        if (!succeeded) [ErrorHandler handle:@"save installation failed" forError:error];
    }];
}

但这不起作用,
任何想法?

这是我的快速代码,它有效:

    // Resets badge number in parse
    var installation = PFInstallation.currentInstallation()
    if installation.badge != 0 {
        installation.badge = 0
        installation.saveInBackgroundWithBlock(nil)
    }

    // Resets badge number in app
    if application.applicationIconBadgeNumber > 0 {
        application.applicationIconBadgeNumber = 0
    }

install.badge和application.applicationIconBadgeNumber setter之间似乎存在依赖关系。确保始终设置安装似乎可以缓解这个问题。

let pcur = PFInstallation.currentInstallation()
        print("current badge = \(pcur.badge)")
        if (pcur.badge != 0){
            pcur.badge = 0
            pcur.saveInBackgroundWithBlock({
                (succeeded,error) in
                print("badge save success = \(succeeded)")
                application.applicationIconBadgeNumber = 0
            })
        }

使用Parse(1.14.2),Xcode 8和ios 10,添加:

    UIApplication.shared.applicationIconBadgeNumber = 0
AppDelegate 类中的 applicationDidBecomeActive 方法内的

也会将解析服务器上的徽章重置为零。
