ios - FireMonkey iOS RAD Studio XE2-在从URL加载的表单上显示图像

是否可以在iOS的FMX表单上放置TImage并将URL中的图像(jpg)加载到要在iOS应用中显示的TImage中？

我尝试没有成功。任何提示或指向正确方向的方法都值得赞赏。

最佳答案

将TButton，TIm​​ageControl和TIdHttp拖放到Firemonkey表单上，此代码将从网络上提取图像:

procedure TForm1.btnReadWebImgClick(Sender: TObject);
begin
  ReadWebImage('http://www.gravatar.com/avatar/5af5f8c5f88c6c237745e9472a31410f?s=32&d=identicon&r=PG');
end;
procedure TForm1.ReadWebImage(imgAddress: string);
var
  memStream: TMemoryStream;
begin
  memStream := TMemoryStream.Create;
  try
    idhttp1.Get (imgAddress,memStream);
  except
    ShowMessage('Image not found at:'+imgAddress);
    memStream.Free;
    exit;
  end;
  try
    memStream.Position := 0;
    ImageControl1.Bitmap.LoadFromStream(memStream);
  finally
    memStream.Free;
  end;
end;
