通知提醒 MiniApp - PythonIDE Docs

演示 notification 请求权限与 schedule，并用 storage 持久化表单偏好。

#预期效果

运行后会出现通知提醒表单，权限、延迟分钟、本地提醒和取消操作都有可见反馈。

#完整示例

python

import appui
import notification
import storage

STORE_KEY = "reminder_demo_settings"

state = appui.State(
    title="喝水提醒",

def body():

                            .button_style("bordered_prominent"),
                        appui.Button("取消提醒", action=cancel_reminder)
                            .button_style("bordered"),
                        appui.LabeledContent("状态", value=state.status),

                    header="操作",
                ),
            ]
        ).navigation_title("通知提醒")
    ).on_appear(load_saved_settings)


appui.run(body, state=state, presentation="fullscreen_with_close")

#关键技巧

先 request_permission()，再用稳定 identifier 调用 schedule / remove_pending 便于覆盖或取消。
request_permission() 返回 dict，无需 json.loads。
用户偏好用 storage.get_json / set_json 在 on_appear 与 on_change 中同步。
