在我的 iOS 应用程序中，我一直在使用名为"iOS KML Framework"的框架。我已将各种 kml 文件添加到我的地图中，现在我使用以下代码创建了一个简单的 KML 文件：

- (void)createCustomKML {
    KMLRoot *root = [KMLRoot new];

    KMLDocument *doc = [KMLDocument new];
    doc.name = @"Custom Route";
    doc.descriptionValue = @"A user created route";
    root.feature = doc;

    KMLPlacemark *placemark = [KMLPlacemark new];
    placemark.name = @"Custom Route";
    placemark.descriptionValue = @"A user created route";
    [doc addFeature:placemark];


    KMLLineStyle *lineStyle = [KMLLineStyle new];
    [lineStyle setColor:@"FF0000FF"];
    [lineStyle setWidth:2.0];

    KMLStyle *style = [KMLStyle new];
    style.lineStyle = lineStyle;
    [placemark addStyleSelector:style];


    KMLLineString *lineString = [KMLLineString new];
    lineString.tessellate = 1;

    KMLCoordinate *coordinate = [KMLCoordinate new];
    [coordinate setLatitude:52.342155];
    [coordinate setLongitude:4.835847];

    KMLCoordinate *coordinate1 = [KMLCoordinate new];
    [coordinate1 setLatitude:52.345301];
    [coordinate1 setLongitude:4.823659];

    [lineString addCoordinate:coordinate];
    [lineString addCoordinate:coordinate1];
    placemark.geometry = lineString;

}

并且想知道我是否可以以某种方式将此文件上传到服务器。这可能吗？如果可以，我应该如何开始？
