OpenCCman 2.2 brings large-file conversion to iPhone and iPad, and a workspace that follows the window on iPhone.
What's new
- iPhone/iPad Pro large TXT files: convert one UTF-8 TXT file larger than 10 MiB and up to 100 MiB directly to a file saved where you choose. Progress and cancellation are shown; the current draft and result stay in place, and homepage conversions are not used. A finished result is kept until you save or delete it, even after an app restart.
- Foreground and safe: conversion runs while the app is open and stops safely if the app moves to the background or the device locks.
- Workspace follows the window on iPhone: wide windows can show source and result side by side. Main actions, Back and Close now use the system navigation bar.
- Clearer Pro prompt: iPhone and iPad use a system alert, and a pending file error is shown after the prompt or Pro page closes instead of being lost.
- Mac menu bar icon by default: the icon is shown unless you turned it off before; an earlier on/off choice is kept. Settings switches use an updated style.
- Fixes: ⌘, and ⌘P open Settings and Pro on Mac even when More is in the toolbar overflow menu, keeping your reading position. Long import hints wrap in narrow Mac windows. Workspace panes keep their height after you return from Settings or Pro. Each new window starts at the home screen, and a finished file result can still be saved after the exporting window closes.
Compatibility
The app still requires iOS/iPadOS 15+ or macOS 12+, and the homepage allowance remains 12 conversions per day. The iPhone/iPad file workflow is Pro only, single-file and UTF-8. Drag and drop and ordinary editor imports remain limited to 10 MiB on every device. Mac Pro direct file conversion remains up to 1 GiB. Batch conversion and Big5/GBK decoding are not supported. Experimental capacities above 100 MiB on iPhone/iPad and above 1 GiB on Mac are not enabled.
简体中文
2.2 让 iPhone 和 iPad 上的 Pro 用户可将单个大于 10 MiB、最多 100 MiB 的 UTF-8 TXT 直接转换为新文件，并保存到自选位置。转换过程显示进度、可随时取消，当前稿件和结果保持原样，也不计入主页次数。转换在应用打开时进行，切到后台或锁屏会安全中止。已完成的结果在保存或删除前一直保留，重启应用也不丢失。
iPhone 的工作区改为按窗口大小排列，宽窗口可左右对照原文和结果，主要操作、返回和关闭按钮移入系统导航栏。Pro 提示改用系统提醒。Mac 菜单栏图标默认显示，之前手动设置过的选择保持不变。「更多」收进 Mac 工具栏溢出菜单时，⌘, 和 ⌘P 仍可使用。
编辑区导入和拖放仍以 10 MiB 为上限；Mac Pro 文件转换仍最大 1 GiB。最低系统仍为 iOS/iPadOS 15 和 macOS 12。
