【问题描述】:

我需要将 BLUETOOTH LOW ENERGY (ble) 添加到我的 xamarin.ios 应用程序中,该应用程序是在与我的 Macbook 配对的 Windows Visual Studio 上构建的。 xamarin.ios 上的 BLE 需要 info.plist 中的 NSBluetoothPeripheralUsageDescription。

但是,我不知道如何在 Visual Studio 中使用 info.plist GUI。

    【解决方案1】:

    要添加它,我用记事本(或任何文本编辑器)打开 info.plist 并插入行... NSBluetoothPeripheralUsageDescription
    测试我们的设备是否支持 BLE
    ...接近尾声。

    示例...

      【解决方案2】:

      但是,我不知道如何在 Visual Studio 中使用 info.plist GUI。

      有两种方法可以在 Visual Studio 中为info.plist 添加NSBluetoothPeripheralUsageDescription

      一个XML(Text)Editor

      打开

      然后在&lt;dict&gt;&lt;/dict&gt;下面添加如下:

      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
      <plist version="1.0">
      <dict>
          ...
          <key>NSBluetoothPeripheralUsageDescription</key>
          <string>Allow NSBluetoothPeripheralUsageDescription </string>
      </dict>
      </plist>
      

      另一种方式是用Generic Plist Editor打开的:

      然后可以点击+按钮选择Privacy - Bluetooth Peripheral Usage Description并输入Value。
