Загрузить KML-файл на сервер

Question

В моем приложении iOS я использовал фреймворк под названием "iOS KML Framework". Я добавил все виды KML файлы к моей карте, и теперь я создал простой KML файл с этим фрагментом кода:

- (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; 

} 

и было интересно, смогу ли я каким-то образом загрузить этот файл на сервер. Возможно ли это, и если да, то как мне начать?
