iOS如何显示桌面应用图标上的推送消息数（大神勿进）

    //获取用户授权

    if (version >= 8.0) {

        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge categories:nil];

        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

    }

    //注册消息推送

    if (version >= 8.0) {

        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge categories:nil];

        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

        [application registerForRemoteNotifications];

    }

    //设置推送消息个数

    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:10];
