display.loadRemoteImage(" http://developer.anscamobile.com/demo/hello.png"," GET",networkListener," helloCopy.png",system.TemporaryDirectory,50,50 )

您好,我想通过以下方式从我的服务器获取ARRAY图像:

data [i] .image = display.loadRemoteImage(URLlimpia," GET",networkListener," LOGO" .. i .." .png", system.TemporaryDirectory)

但是图像总是出现在模拟器屏幕上,我想保存在任何地方以便稍后在列表中显示。

我该怎么做?

* 如何在屏幕上显示时清除图像?

感谢

试试这个:

local function networkListener( event )
        if ( event.isError ) then
                print ( "Network error - download failed" )
        else
                event.target.isVisible = false
        end

        print ( "RESPONSE: " .. event.response )
end

display.loadRemoteImage( "http://www.coronalabs.com/demo/hello.png", "GET", networkListener, "helloCopy.png", system.TemporaryDirectory, 50, 50 )

如果您不想立即显示图像,则应使用 network.download()而不是display.loadRemoteImage()

在你的例子中:

local params = {}
params.progress = true
for i=1,n do
    network.download(
        URLlimpia,
        "GET",
        networkListener,
        params,
        LOGO" .. i .. ".png",
        system.TemporaryDirectory
        )
end
