Question

我需要在带有10.2.1的iOS设备上发送带有使用Corona SDK构建的应用附件的电子邮件。我曾经一度构建了一个能够发送带附件的电子邮件的Corona应用程序，它运行得很好。现在，从iOS 10.2.1开始，它似乎无法工作，我无法判断它是否因为我编写的代码错误或native.showPopup与iOS 10.2.1不兼容。

我正在使用Corona build 2017.3059。

此外，我已使用native.canShowPopup( "mail" )检查了我的设备（iPhone 6），并指出该设备上提供了邮件弹出功能。

以下是我正在使用的代码。

local widget = require( "widget" )

-- Function to handle button event
local function sendMail( event )
   if ( "ended" == event.phase ) then
      if ( native.canShowPopup( "mail" ) ) then
         native.showAlert( "Alert!", "Mail IS available on this device", { "OK" } )
         local options =
         {
            to = { "john.doe@somewhere.com", "jane.doe@somewhere.com" },
            cc = { "john.smith@somewhere.com", "jane.smith@somewhere.com" },
            subject = "My High Score",
            isBodyHtml = true,
            body = "<html><body>I scored over <b>9000</b>!!! Can you do better?</body></html>"
         }
         native.showPopup( "mail", options )
      else
         native.showAlert( "Alert!", "Mail NOT available on this device", { "OK" } )
      end
   end
end

-- Create the widget
local mailButton = widget.newButton(
{
   label = "Mail",
   fontSize = 64,
   onRelease = sendMail, -- this is my function to send mail
   labelColor = { default={ 1, 1, 1 } },
   labelAlign = "center",
   emboss = false,
   shape = "roundedRect",
   width = 200,
   height = 100,
   cornerRadius = 13,
   fillColor = { default={1,0,0}, over={0,1,1} },
   strokeColor = { default={1,1,1}, over={1,1,1} },
   strokeWidth = 4
}
)

mailButton.x = display.contentCenterX
mailButton.y = display.contentCenterY

Answer 1

我能够让这个工作。实际上有两个问题：

1）由于某些原因，我的设备上的电子邮件帐户存在问题。

出于某种原因，我不确定为什么，我不得不删除我的电子邮件帐户并恢复它们，这似乎解决了问题。我觉得这是一种非常常见的配置，我在Apple iOS Mail应用程序上安装了两个Gmail帐户。但是删除它们并恢复它们就可以了。

2）您无法在触发电子邮件之前触发警告框

在我的代码正常工作之前，我不得不摆脱：

native.showAlert( "Alert!", "Mail IS available on this device", { "OK" } )

所以工作代码是：

local widget = require( "widget" )

-- Function to handle button event
local function sendMail( event )
   if ( "ended" == event.phase ) then
      if ( native.canShowPopup( "mail" ) ) then
         local options =
         {
            to = { "john.doe@somewhere.com", "jane.doe@somewhere.com" },
            cc = { "john.smith@somewhere.com", "jane.smith@somewhere.com" },
            subject = "My High Score",
            isBodyHtml = true,
            body = "<html><body>I scored over <b>9000</b>!!! Can you do better?</body></html>"
         }
         native.showPopup( "mail", options )
      else
         native.showAlert( "Alert!", "Mail NOT available on this device", { "OK" } )
      end
   end
end

-- Create the widget
local mailButton = widget.newButton(
{
   label = "Mail",
   fontSize = 64,
   onRelease = sendMail, -- this is my function to send mail
   labelColor = { default={ 1, 1, 1 } },
   labelAlign = "center",
   emboss = false,
   shape = "roundedRect",
   width = 200,
   height = 100,
   cornerRadius = 13,
   fillColor = { default={1,0,0}, over={0,1,1} },
   strokeColor = { default={1,1,1}, over={1,1,1} },
   strokeWidth = 4
}
)

mailButton.x = display.contentCenterX
mailButton.y = display.contentCenterY
