如何调用“关闭飞机模式”通知 [英] How to invoke "Turn Off Airplane Mode" notification
问题描述
在许多应用程序(例如邮件应用程序)中,如果设备处于飞行模式,则会弹出一条通知,说关闭飞行模式或使用Wi-Fi访问数据。
In many applications, such as the Mail app, if the device is in airplane mode a notification will pop up that says "Turn Off Airplane Mode or Use Wi-Fi to Access Data."
我认为如果我的应用程序尝试访问互联网,这将自动调用,但它不是。是否有特殊的方法来执行此操作,或者如果没有,如何检查设备是否处于飞行模式,并提供指向设置的链接以禁用它?
I thought that this would automatically be invoked if my app tries to access the internet, but it is not. Is there a special method to do this, or if not how can I check if the device is in airplane mode and provide a link to Settings to disable it?
推荐答案
如果您将 UIRequiresPersistentWifi
键添加到您的 Info.plist
code> YES ,那么如果您处于飞行模式,您将在启动时看到标准的关闭飞行模式...弹出窗口。
If you add the UIRequiresPersistentWifi
key to your Info.plist
and set it to YES
, then if you're in Airplane mode, you'll get the standard "Turn Off Airplane Mode..." popup on launch.
