【问题描述】：

我有这段代码可以在 ios7 中运行。它使我能够关闭声音、警报和徽章。如果showMessage,showBadge or show sound 设置为零，则相应的 UIremote 类型也会关闭。众所周知，iOS8 远程通知已经改变。有人可以指导我如何使其适用于 iOS 8 吗？

    UIRemoteNotificationType notificationType = UIRemoteNotificationTypeNone;
    if (showMessage == 1 )
        notificationType |= UIRemoteNotificationTypeAlert;
    if (showBadge == 1 )
        notificationType |= UIRemoteNotificationTypeBadge;
    if (showSound == 1 )
        notificationType |= UIRemoteNotificationTypeSound;
 [[UIApplication sharedApplication] registerForRemoteNotificationTypes:notificationType];

这是我尝试过的，但我收到错误 No visible @interface 'UIApplication' declares selector 'registerForUserNotificationSettings:'

     UIUserNotificationType  userNotificationType = UIUserNotificationTypeNone;
    if (showMessage == 1 )
        userNotificationType |= UIUserNotificationTypeAlert;
    if (showBadge == 1 )
        userNotificationType |= UIUserNotificationTypeBadge;
    if (showSound == 1 )
        userNotificationType |= UIUserNotificationTypeSound;
    [[UIApplication sharedApplication] registerForUserNotificationSettings:userNotificationType];

【参考方案1】：

在您的代码中，您传递的是 UIUserNotificationType 对象，但您需要传递 UIUserNotificationSettings 对象。

UIUserNotificationType notificarionType = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:notificarionType categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
