我的iPhone应用程序需要持久的网络连接...如何指定UIRequiredDeviceCapabilities？ [英] My iPhone app needs a persistent network connection...how to specify UIRequiredDeviceCapabilities?

问题描述

我正在尝试在Info.plist文件中设置UIRequiredDeviceCapabilities属性。我的应用需要持久的网络连接。如果我查看wifi键的定义，它会说：

I'm trying to set the UIRequiredDeviceCapabilities properties in my Info.plist file. My app requires a persistent network connection. If I look at the definition for the "wifi" key, it says:

如果您的应用程序
需要访问权限，请包含此密钥设备的网络
功能。

Include this key if your application requires access to the networking features of the device.

所以：wifi键表示我需要WiFi，如关键名称会建议吗？或者这是否意味着我只需要网络访问，因为密钥定义会建议？

So: does the "wifi" key indicate that I need WiFi, as the key name would suggest? Or does it mean that I simply need network access, as the key definition would suggest?

推荐答案

如果没有此密钥，iPhone将会在一定量的不活动后禁用wifi。使用此键，可以为您的应用永久启用wifi。

Without this key, the iPhone will disable wifi after a certain amount of inactivity. With this key, the wifi is kept permanently enabled for your app.
