【TechWeb】12月10日消息，苹果公司今日正式向iPhone用户发出升级邀请，呼吁用户更新至iOS 26系统，并重点介绍了三项高频使用的新功能，以提升用户体验。此次更新标志着苹果在系统设计上的重大革新，旨在加速新系统的普及。
iOS 26引入了全新的“Liquid Glass”界面设计，这是自iOS 7扁平化风格以来最大的视觉变革。用户只需从相册中选择照片，系统即可通过“空间场景”技术自动处理景深信息，生成动态视差效果，轻微摇动设备便能感受到画面主体跃然屏上的沉浸感，显著增强锁屏界面的趣味性。
除视觉创新外，苹果还强调了三大实用功能：
一是“未知来电筛选”服务，系统可代接未保存号码来电，实时转录对方说明事由，帮助用户判断是否接通，有效减少骚扰电话干扰。
二是AirPods遥控拍摄功能，用户通过双击或长按耳机即可控制iPhone相机快门，便于独自拍摄照片或录制Vlog，操作更加便捷流畅。
三是音乐播放体验升级，新增曲目间“自动过渡”淡入淡出效果，以及实时歌词翻译功能，支持外文歌曲歌词即时转换为用户所选语言，提升跨语种音乐欣赏体验。
苹果在宣传中热情呼吁：“现在就更新起来，早一步成为点亮iOS26神技能的人。”目前，iOS 26已面向兼容机型全面推送，涵盖近年主流iPhone设备。此次更新不可逆，用户无法降级回旧版本，且苹果未来可能逐步缩减对iOS 18的安全支持。
需要注意的是，从iOS 18升级到iOS 26是不可逆的，苹果官方也不提供降级回旧版本的方法。目前，苹果仍在为选择继续使用iOS 18的用户提供安全更新，但这种支持可能在未来几个月内逐步缩减。（宜月）
